2: The Slavs and Their Neighbors
<< 1: The Geographical and Ethnographical Background || 3: Toward Political Organization >>
THE SLAVS AND EURASIA
Eastern Europe is sometimes called Western Eurasia. This is correct, however, only with
regard to the frontier region of geographical Europe which was outside the historical
European community. And so far as prehistory is concerned, we may consider as Eurasian
that eastern part of the great European Plain which was inhabited by non-European peoples
whose closest kin were living in Asia. These peoples were the eastern neighbors of the
Slavs, whose own original home, situated in the heart of Europe, could hardly be included
in any Eurasia.
It is possible, however, that the Balto-Slavic homeland in East
Central Europe was at a very early date partly occupied by some of the Finnish tribes
which, having been gradually pushed back, remained the northeastern neighbors of both
Balts and Slavs until the present. These tribes of Mongol race were in general on a lower
level of culture and without any political organization. Such of them as lived nearest to
the Baltic Coast became closely associated with the Indo-European Balts and developed more
successfully than the others. In that region tribes of Baltic and Finnish origin are
sometimes not easy to distinguish. The name Aestii, used by Tacitus, seems to
include both of them, and while the Ests of later centuries—the ancestors of the
present Estonians—definitely belong to the Finnish group, as do the Livs who gave
their name to Livonia where they lived among the Baltic Letts, the question whether the
Curs, after whom Curland was named, were of Finnish or Baltic origin is difficult to
decide.
Larger and more numerous Finnish tribes were living not only in
Finland itself, which does not appear in history before the Swedish conquest in the
twelfth century when it first became and for a long time remained associated with
Scandinavia, but also in the Volga Basin and north of it as far as the geographical limits
of Europe, the Arctic Ocean and the Ural Mountains. The colonization of the Volga region
by tribes belonging to the eastern branch of the Slavs, which was to become so important
from the eleventh century on, certainly did not start before the seventh or eighth
century, and then on a very modest scale. But from the beginning it was a process of
absorption and gradual Slavization of the poorly developed Finnish tribes whose names
appear, however, in those of some of the earliest Slavic settlements.
Different were the relations between the Slavs and the Eurasian
peoples who were living south of the Finns. Those peoples either belonged to the Mongol
race, like the Finns, but to its Turkish group, or to the Iranians, that is, to the
Asiatic branch of the Indo-European race. In contrast to the rather passive Finns, these
peoples of an aggressive character frequently invaded and at least temporarily dominated
their Slavic neighbors, even in the prehistoric period. When such invasions were repeated
in the later course of history, the Slavs and the Asiatic conquerors, exclusively
Turco-Tartars, are easy to distinguish from one another. On the contrary, there is a great
deal of confusion with regard to the names which appear in the steppes north of the Black
Sea from the Cimmerian period (1000—700B.C.) to the establishment of the Bulgar and
Khazar states in the seventh century A.D. The ethnic origin of each of these peoples is
highly controversial, and since they all exercised a strong influence upon the eastern
Slavs, after controlling them politically, the question has been raised whether even
undoubtedly Slavic tribes were not originally under a foreign leadership which would
explain some of their rather enigmatic names.
On the other hand, it seemed equally justifiable to look for
Slavic elements which might have been included among the leading Eurasian peoples. It is
indeed quite possible that when the Cimmerians, of Circassian (Caucasian) or Thracian
origin were replaced (700-200 B.C.) as a ruling “superstructure” by the
Scythians, that name covered various tribes of different ethnic stock, including Slavs in
addition to the leading “Royal Scythians” who were well known to Herodotus and
probably of Iranian origin. The same might be said about the Sarmatians who took the place
of the Scythians from about 200 B.C. to 200 A.D. Again, most of their tribes, including
the Alans, who were the last to come from Asia but who seem to have played a particularly
important role in the first centuries of the Christian era, were certainly of Iranian
origin. But the loose federation of these Sarmatian tribes probably included Slavic
populations also, although later traditions, which saw in the Sarmatians the early
ancestors of the Slavs, particularly of the Poles, are of course purely legendary.
The following invasions of the Germanic Goths and of the Mongol
Huns, both of whom only temporarily occupied the Slavic territories before crossing the
frontiers of the Empire, were of a different character. Better known than their
predecessors, neither of these peoples had anything in common with the Slavs and they left
no traces in Central or Eastern European history. But some Iranian elements seem to have
survived through the Gothic (200—370 A.D.) and Hunnic period (370—454 A.D.).
According to recently expressed opinions, some tribes of the Alans continued to control
the Azov region where they mixed with the eastern tribes of the Slavic Antes. Even the
Croats and Serbs, that is, the leading tribes of the southern branch of the Slavs, as well
as their names, would have been of Iranian origin.
Turning from these highly controversial hypotheses to the
historical facts of the sixth and seventh centuries, the Avar domination of the eastern
and southern Slavs must be stressed as one of the most dangerous of the Asiatic invasions.
Coming from Mongolia under the pressure of their Turkish neighbors, the Avars appeared at
the gates of Europe, north of the Caucasian region, in 558. They soon became a serious
threat to the Eastern Empire, and at the end of the eighth century they were finally
defeated by Charlemagne, restorer of the Western Empire. The Slavs, however, who suffered
cruelly from these conquerors, had to face another twofold pressure coming from the
Eurasian East at the same time.
In the northeast a branch of the Bulgars, a Turco-Ugrian people
who at the beginning of the seventh century had created a “Great Bulgarian”
Empire in the Don region, established a state in the middle Volga area after the fall of
that empire. These Volga Bulgars, who must be distinguished from the main body which moved
in the direction of the Balkans, chiefly conquered Finnish territory but for several
centuries also remained an obstacle to further Slavic expansion.
Much more important for the Slavs was the foundation of the
Khazar “Kaganate” in the southeast. The Khazars were another Asiatic tribe,
probably mixed ethnically, which first appeared north of the Caucasus around 570, when
they were apparently under Turkish control. After breaking up Great Bulgaria, the Khazars
succeeded in creating a large state for themselves. This reached from the Caucasus to the
lower Volga and the lower Don and from the very beginning included some Slavic
populations. Uniting peoples of various races and religions under their
“Khagan,” as their supreme ruler was called, they were eventually converted to
the Jewish faith. The Khazars had to fight the Arabs in the Caucasian region and to face
the rivalry of Byzantium in the Azov region. But almost simultaneously they also started
to advance in the opposite, northwestern, direction. Here they reached the height of their
expansion in the first half of the ninth century when they conquered the Slavic tribes
which had crossed the Dnieper River. They even reached Kiev and demanded tribute from that
area.
The Khazar domination was, however, much milder than any other
which these Slavs had known, and it did not remain unchallenged by other invaders of the
same territory. When the Khazars first met the opposition of Norman vikings is a moot
question which must be studied in connection with the controversial antecedents of the
creation of the Kievan state later in the ninth century. But even before that, the Khazars
clashed in the Kiev region with the Magyars, an Ugrian (Mongolian) people who stopped
there for about three hundred years on their way from the Urals to the Danubian Plain.
This was another tribe, though probably less numerous, which ruled over some eastern Slavs
before penetrating between the western and southern branch of the Slavic peoples, not
without experiencing some Slavic influence.
That Slavic influence proved much stronger in the case of those
Bulgars who, instead of moving up the Volga River to the north, proceeded southward toward
the lower Danube. Long before the Bulgars crossed that river and penetrated into imperial
territory, their clans absorbed so many East Slavic elements that when they settled in the
Balkans—not much later than the southern Slavs, the Serbs and Croats—they were
already Slavized to a large extent. The role which they played in the history of the
eastern Slavs was, however, only temporary and rather limited.
In general, however, it was the eastern branch of the Slavs,
first called Antes in the earliest sources and later known under the enigmatic name
of Rus, which as a natural consequence of their geographical situation had already
had the closest relations with the various Asiatic invaders of eastern Europe in the
prehistoric period. These non-European influences, of whatever kind, hardly affected the
two other branches of the Slavic people, except through the Avars and Magyars. The western
Slavs, especially the descendants of the Venedi, were practically not touched at all.
This basic fact contributed, of course, to the growing
differentiation among the three main Slavic groups. But it also created differences within
the eastern group itself; between those Antes who remained in the original Slavic homeland
in East Central Europe, where they constituted a numerous, native population and easily
absorbed any foreign element which passed through their territory, and on the other hand,
those Slavic pioneers who penetrated beyond the Dnieper Basin into the vast intermediary
region which might be called Eastern Europe or Western Eurasia.
In that region the outposts of the Slavic world were colonists
who were scattered among and mixed with Finno-Ugrian, Turkish, or Iranian populations
whose number increased through continuous migrations and invasions from Asia. With only
the exception of most of the Finnish tribes, all these Eurasian peoples were conquerors,
stronger and better organized than the Slavs and therefore in a position to exercise a
permanent pressure and influence upon them. The question remained open, therefore, whether
that whole area, with its mixed population subject to so many different cultural trends,
would ever become historically a part of Europe.
THE EARLIEST RELATIONS BETWEEN SLAVS AND TEUTONS
The Germanic or Teutonic peoples were originally divided into three groups or branches,
just as were the Slavs, with the difference that, in addition to a western and an eastern,
there was a northern group although no southern. More than any other European peoples, all
of them had close relations with the native inhabitants of East Central Europe, the Slavs
and the Balts. It was the quasi-permanent Germanic pressure exercised upon the Balto-Slavs
from the West which corresponded to the Eurasian pressure from the East. A theory was even
developed, according to which the Slavs would have been from time immemorial under a
twofold foreign domination, either German or Turco-Tartar, with lasting consequences of
that situation in the whole course of history. And even more general among German
scholars is the opinion that a large part of the historical Slavic homeland in East
Central Europe had been originally inhabited in prehistoric times by Germanic tribes which
left that area only during the great migrations, while the Slavs followed them and took
their place.
Without returning to that controversy, it must be admitted that
during the earlier phase of these migrations, before they definitely became a movement
from East to West, some Germanic tribes spread all over East Central Europe but only as
temporary conquerors. For obvious geographical reasons these tribes were those of the East
Germanic group, the group which proved particularly active in the migration period and
which—eventually penetrated farther than any other Teutons in a southwestern
direction, only to disappear completely. In Central Eastern Europe their invasion left
nothing but a tradition of ruthless domination by the Goths, who were the leading tribe
among those East Germanic ones.
This tradition was particularly strong among the Baltic
peoples, but for a short time, under king Ermanaric (about 3 50-370 A.D.), an Ostrogothic
empire seems to have also included most of the Slavic peoples. Defeated in the following
years by Huns and Alans, however, the Ostrogoths crossed the Danube and in the well-known
battle of Adrianople (378) started their invasion of the Roman Empire which led them far
away from Slavic Europe.
At the Baltic shores the Gothic occupation was soon followed by
a long series of raids and invasions, equally dangerous for Balts and Slavs, which came
from another branch of the Germanic peoples, the northern. Long before the Normans played
their famous role in the history of Western Europe, bold expeditions of Scandinavian
vikings not only crossed the Baltic but laid out the first trade routes through Eastern
Europe, as far as the Caspian and Black Sea regions, where they established contacts with
the Asiatic world. Arabic sources seem to indicate that the earliest of these connections
were established along the Volga without touching the original Balto-Slavic territory. The
opinion has also been expressed that Norsemen appeared and even created some kind of state
organization in the Azov region, perhaps under the name of Rus, long before the Rus
of the later ninth century followed the shortest route from Scandinavia to Greece, and
formed the historical Russian state with its centers at Novgorod and Kiev.
But again, these are merely hypotheses, and the historian is on
much more solid ground if before studying that momentous intervention of Scandinavian
elements in the destinies of the Eastern Slavs, he turns, in the chronological order, to
the first recorded contacts between the western group of the Teutonic peoples the Germans
proper and their Slavic neighbors. These were, of course, the Western Slavs and also the
western tribes of the Southern Slavs, the ancestors of the Slovenes of today. And this is
precisely the most important problem of all in the relations between Slavs and Teutons, a
problem which in uninterrupted continuity and increasing significance was to last until
our times.
The whole issue started when the westward movement of the
Germanic tribes, after reaching the extreme limit of the Atlantic Ocean, was replaced by a
return drive in the opposite direction, later known as the Drang nach Osten. Even
if at the beginning it was a re-conquest of territories which Slavic tribes had occupied
during the preceding migrations, it soon turned into a systematic aggression on a long
front from the mouth of the Elbe to the Alpine valleys, soon threatening the Slavs in what
undoubtedly was their original territory. As long as the German tribes which first clashed
with the Slavs and tried to push them back were pagans like their opponents and hardly
better organized politically, the chances were almost even in spite of the more warlike
character of the Germans. But the situation changed completely when, after the conquest
and conversion of the Saxons by Charlemagne and the inclusion of the Duchy of Bavaria in
his empire, that very Christian Empire created by the Franks became the powerful neighbor
of all Slavic tribes on the whole western front.
For the entire further course of Slavic history, that new
situation had far-reaching consequences. Those Slavs who lived near the western limits of
their homeland now came into permanent contact with Western culture, with both Roman
tradition and the Catholic church. But as the first representatives of that world, they
met those Germans who themselves had only recently accepted that culture and now wanted to
use its values, particularly the propagation of the Christian faith, as tools of political
domination. That danger had already appeared under Charlemagne, but it became even greater
when, after the division of his supranational empire in 843 and the following partitions,
the Slavs had the East Frankish kingdom as an immediate neighbor. This purely German
state, the Germany of the future, had its likeliest possibilities of expansion precisely
in the eastern direction through the conquest of Slavic territory and its organization
into German marches.
In that relentless struggle which started at the end of the
eighth century, three sectors of the long German-Slavic frontier must be distinguished.
There was first, in the North, the plain between the sea and the Sudeten Mountains. Here
the Germans had to do with the numerous Polabian and Lusatian tribes which in the past had
even crossed the Elbe-Saale line. As soon as Saxony was organized as one of the largest
German duchies, the Slavs were pushed back from the mouth of the Elbe and the southeastern
corner of the North Sea to the southwestern corner of the Baltic Sea. The series of
marches which were supposed to protect the German territory and serve as stepping stones
of further expansion, started with the Northern march which was created toward the end of
the ninth century at the expense of the Obotrites, the Slavic population of what was later
called Mecklenbnrg. The same method was tried in the whole belt east of the middle Elbe as
far as Lusatia. Already under the Carolingians, in the course of that same ninth century,
that area was something like a German sphere of influence, but in view of the fierce
resistance of the Veletian group of the Slavs and of the Lusatian Serbs (Sorbs), the final
creation of German marches had to wait until the following century, when the pressure
increased under the kings of the new Saxon dynasty.
Of special importance was the next sector of the front, the
central bastion of Bohemia, surrounded by mountains which stopped the German advance or
made it change its usual methods. Fights with Bohemian tribes had already started in the
time of Charlemagne, but on the one hand their land proved difficult to conquer, and on
the other there appeared among their princes a disposition to accept the Christian faith
voluntarily in order to avoid a forcible conquest. As early as 845 some of these princes
came to Regensburg where they were baptized, probably recognizing a certain degree of
German suzerainty. Others, however, turned at about the same time toward a first center of
Slavic power which was being created by their kin, the princes of Moravia, in an area
which still was beyond the reach of German invasions and in direct contact with the
south-Slavic Slovenes in the Danubian Plain, where the memory of Samo’s state had
perhaps not entirely disappeared.
The Slovenes themselves were, however, threatened at least from
the eighth century in their Alpine settlements where Bavarian colonization was in
progress. Acting as overlord of the dukes of Bavaria, Charlemagne there created a first
march on what was later to be the territory of Austria, chiefly as a defense against the
Avars, but also in order to control the Slavic population after the fall of the Avar
power. The missionary activities of the German church, especially of the bishops of
Salzburg and Passau, also contributed to strengthening Bavarian influence as far as the
former Roman province of Pannonia, and under Charlemagne’s son Louis the authority of
the empire was temporarily recognized even by the Croats, particularly after the
suppression of a revolt by the Croat prince Ludevit in 822.
That German advance far into the territory of the Southern
Slavs was only temporary and exceptional, but even so it resulted in a conflict with
faraway Bulgaria and in a contact between Frankish and Byzantine influence. It is,
therefore, against the whole background of these international relations in the Danubian
region and of contemporary developments in the Balkans, that the rise and fall of the
so-called Moravian Empire must be studied. But before approaching that important turning
point in the history of East Central Europe, a more general consequence of the earliest
relations between Slavs and Teutons ought to be emphasized.
Just because the German power was so much stronger, the growing
danger forced the Slavs at last to develop their own political organization and to
cooperate in larger units under native leadership. In many cases they proved quite capable
of doing so in spite of many unfavorable circumstances. In opposition to foreign
aggressors whose language they were unable to understand, they became conscious of their
own particularity. But in contradistinction to the Eastern Slavs who had to face
semibarbarian Asiatic invaders, mostly pagans like themselves, the Western Slavs had to
realize that they could not resist their opponents without themselves entering the realm
of that Roman culture which was the main factor of German superiority, and most important,
without becoming Christians like their neighbors. Those among the Slavs who failed to do
so were doomed in advance. The others had to find ways and means of doing it without an
exclusively German intermediary by safeguarding their independence and by organizing on
their own account the East Central European region. In the critical ninth century, one of
these possible ways seemed to be cooperation with the eastern center of Christian and
Greco-Roman culture, with Byzantium.
THE SLAVS AND THE BYZANTINE EMPIRE
Long before the Croats were touched by the Frankish conquest, that same South-Slavic
people, together with their closest kin, the Serbs, had entered into much more stable
relations with the Eastern Roman Empire and with the Eastern church which was not yet
separated from Rome. These relations were, however, of an entirely different character. In
this case it was the Slavs who were the invaders. After participating, from the end of the
fifth century, in various raids of other “barbarian” tribes into imperial
territory, they threatened Byzantium then the only Christian Empire even during the
brilliant reign of Justinian I, who by some earlier scholars was wrongly considered to
have been of Slavic origin. Through the sixth century the Slavic danger, combined with
that from their Avar overlords, constantly increased. More and more frequently they
penetrated far into the Balkans, until in the first half of the seventh century the
Emperor Heraclius permitted some of their tribes, freed from the Avars, to settle in the
devastated lands south of the Danube.
These Slavs, soon converted to the Christian faith, were under
the leadership of Chrovatos whose name, probably Iranian, was taken by his people, later
known as Croats, while other tribes of the same group received the name of Serbs, which
according to some authorities would be derived from servus (slave). Definitely
established in the area which they occupy today, the Serbo-Croats made the region
practically independent from Byzantium, defending themselves at the same time against the
Avars. Culturally, however, they came under the influence of Byzantium, which never ceased
to consider their territory the old Illyricum part of the Eastern Empire. Greek
influence was, of course, particularly strong among the Serbs, who moved deeper into the
Balkans and remained the immediate neighbors of the Greeks. The Croats, on the other hand,
who established themselves farther to the northwest, were soon exposed to Western
influences. This explains the growing differentiation between the two peoples, which were
of common origin and continued to speak the same language. With the ever stronger
opposition between Eastern and Western Christendom, the separation between Serbs and
Croats was to become much also deeper, a distinctive feature of the history of the
Southern Slavs.
But already in the early days of their settlements in regions
well to the south of their original homeland, another problem proved to be of lasting
importance. The problem of their relations with an entirely different people who
simultaneously invaded the Byzantine Empire and after crossing the lower Danube settled
permanently on imperial territory in the Balkans, but east of the Serbo-Croats, not at the
Adriatic but at the Black Sea coast. These were the Bulgars or Bulgarians.
The southern branch of that Turkish people, who as a whole had
played such an important but rather transitory role in Eurasia and the steppes north of
the Black Sea, had already mixed with the Slavic tribes of the Antes in that region. When,
after participating in earlier invasions of the Eastern Empire by the Avars, as had the
Slavs, they definitely crossed the Danube under their Khan or Khagan, Asparukh, in 679, a
Bulgar state was established in northern Thrace in the region of present-day Bulgaria.
That state, however, which soon extended its boundaries in all
directions, had a predominantly Slavic population. For in addition to the foundation of
new states in the northern part of formerly imperial territory, numerous Slavic tribes had
throughout the sixth and seventh century continued to raid the whole Balkan Peninsula and
even Greece proper. Most of them remained there in larger or smaller groups, creating the
so-called Sclaviniae, that is, permanent settlements which without being organized
as political units changed the ethnic character of the whole empire. Some scholars have
even expressed the opinion that the Greek population was completely Slavized, an obvious
exaggeration, since the Slavs rarely succeeded in taking the more important cities which
they besieged, but which remained Greek as did most of the Mediterranean coast. But while
scattered Slavic settlers came under the influence of Greek culture even more than in
Serbia, they in turn so strongly influenced the Bulgar conquerors that even their language
was adopted by the latter, and already in its pagan period the new state must be
considered Bulgaro-Slavic. And gradually the Turkish element was so completely submerged
that Bulgaria simply became one of the South-Slavic nations.
The Byzantine Empire, which continued to have occasional
troubles with its Slavic subjects and even had to move some of them as far away as
Bithynia in Asia Minor, was seriously concerned with the rise of Bulgar power so near to
Constantinople itself. Emperor Justinian II, after defeating Bulgars and Slavs in 690, had
to ask for their assistance in order to recover his throne from a rival, and in reward he
granted to Asparukh’s successor, Tervel, the title of Caesar when he received him in
the capital in 705. In spite of a treaty which Byzantium concluded with Bulgaria eleven
years later, and which established a new boundary line north of Adrianople, there was a
whole series of Greek-Bulgar wars in the course of the eighth century. In 805 Khan Krum,
after contributing in cooperation with the Franks to the fall of the Avars, created a
strong Bulgarian Empire on both sides of the Danube. The role of the Slavic element was
increased, and until Krum’s death in 814 Byzantium, which suffered a terrible defeat
in 811, was seriously threatened by its northern neighbor. Constantinople itself was
besieged by the Bulgars. The relations improved under the new Khan Omortag, who even
assisted Emperor Michael III against a Slavic uprising and turned against the Franks, with
whom he clashed in Croatia. But it was not before the reign of Boris, from 852, that the
conversion of Bulgaria to the Christian faith was seriously considered. This raised
entirely new issues in her relations with Byzantium.
In contradistinction to the restored Western Empire, the
Eastern Roman Empire had no desire for territorial expansion. It wanted, however, to
control the foreign elements which had penetrated within its boundaries and had even
created their own states on imperial territory. Moreover, it was afraid of new invasions
by other barbarian tribes, the first attack of Norman “Russians” against
Constantinople in 860 being a serious warning. In both respects the missionary activity of
the Greek church, under the authority of the Patriarch of Constantinople, closely
cooperating with the Emperor, seemed to be particularly helpful in bringing under
Byzantine influence the Slavic populations of the Balkans, as well as dangerous neighbors,
Slavic or non-Slavic.
That missionary activity, which in general was less developed
in Eastern than in Western Christendom, was greatly intensified under the famous Patriarch
Photius. Through an arbitrary decision by the imperial power, in 858 he replaced the
legitimate Patriarch Ignatius, and this was the origin of a protracted crisis in the
religious life of Byzantium. But he proved to be one of the most prominent leaders of the
Greek church, one who was particularly anxious to promote the spread of Christianity even
among the faraway Khazars, the neighbors of the last Greek colonies on the northern shores
of the Black Sea. It was there that Constantine and Methodius, the Greek brothers from
Salonika, who were equally distinguished as theologians and as linguists, started their
missions in 860 or 861. They failed to convert the Khagan, who decided in favor of
Judaism, but they were soon to be sent to the Slavs of the Danubian region. And at the
same time it became known that Boris of Bulgaria wanted to become a Christian.
In both cases, however, the question had to be decided as to
whether the converts would be placed under the ecclesiastical authority of the
Patriarchate of Constantinople or directly under Rome, a question which had both a
religious and a political aspect that was to be decisive for the whole future of the
Slavs. As yet there was no definite schism between the Roman and the Greek church, but
already there was a growing tension which was intensified by the fact that Pope Nicholas I
did not recognize the appointment of Photius and excommunicated him in 863. Today we know
that even Photius break with Rome in 867 was by no means final, but the whole
ecclesiastical conflict which lasted until 880 prepared the schism of the future. And even
Ignatius, who again occupied the See of Constantinople from 867 to 877, opposed Rome in
the matter of the new Bulgarian church which he wanted to place under his own authority.
The Emperor, too, though eager to remain in good relations with
the Papacy, was adamant in the Bulgarian problem, and finally Boris, who was baptized in
864, after trying to find out which side would grant the greater autonomy to the new
Bulgarian church, decided in favor of Byzantium, a solution which obviously was also
dictated by geographic conditions and by the whole past history of the territory occupied
by the Bulgars. The situation was entirely different in old Pannonia, that is in the
Danubian Basin north of the Serbo-Croat settlements, where during these same years
Constantine and Methodius undertook their most important mission, entrusted to them by
Photius on the invitation of a new Slavic power, the so-called Moravian Empire. The
outcome of their activity was to be of lasting significance, not only for the relations of
the various Slavic peoples with Byzantium but also for the whole future of East Central
Europe.
