other nomad peoples of this zone. From the moment of the strengthening of
Slavic settlement on the Danube, the second stage of expansion of the Slavs to
the south began. The first signs of this can be observed in the middle of the
sixth century. Settlement increases in intensity at the end of the century and
ends about the middle of the seventh century, when considerable areas of the
Balkans were already occupied by the Slavs. The colonisation was preceded in
the first decades of the sixth century and maybe even at the end of the fifth
century by raids by Slavs from beyond the Danube, organised either by the
Slavs themselves, or with the help of other peoples, mainly Bulgars from Little
Scythia (Scythia Minor)inthe region of the delta of the Danube.
The Slavic raids of the first half of the sixth century had a destructive charac-
ter, being carried out mainly for the purposes of looting. They increased in the
reign of Justinian (527–565), when the Byzantine armies were involved in long
campaigns to restore the frontiers of the Roman Empire.

Justinian attempted
to strengthen the north-eastern frontiers, rebuilding many destroyed Danubian
fortresses, and also refortifying existing and building new forts in the interior
of the Balkan peninsula, for example near important passes through the Balkan
mountains. The fortresses themselves could not hold back the tide of northern
barbarians, and from the time of that emperor come frequent (annual, accord-
ing to Procopius) attacks of the Sclavenoi and Antes who spread destruction
and desertion in the whole of Thrace and Illyria, taking loot and herds of cattle,
seizing numerous prisoners, taking fortresses and being faced with only weak
resistance from the imperial armies. In the years 545–551, especially, the pres-
ence of the Sclavenoi was known even in the furthest Balkan provinces. In 550
a large group of Sclavenoi were preparing for an expedition to Thessalonica,
but with the news of the approach of a great Byzantine army they abandoned
this expedition, and moving instead from the area of Naissus (Ni
ˇ
s), ‘crossing
all the mountains of Illyria’, found themselves in Dalmatia.
18
It is also to this
period that we should date the sporadic settlements of small groups of Slavs
in the deserted areas of Moesia Superior and Inferior. We should note too the
presence of certain groups of Slavs in the Byzantine Empire as soldiers.

The appearance of the Avars in this area of Europe additionally complicated
and hastened further developments. This nomadic people arrived about 558 on
the Black Sea steppes, fleeing from central Asia before the Turks and becoming
involved in political struggles between Byzantium, the steppe peoples of the
Black and Azov Sea coasts, and Persia. In defiance of Byzantium they attacked
the Utrigurs and Sabiri and defeated the Antes between the Dnepr and Dnestr.
They then turned their attention to the west, to the Franks, with whom they
