The Albanian settlements in southern Italy and Sicily were founded in 1444, 1464 and 1468; minor immigrations followed in the three succeeding centuries.
The large number of Slavonic local names in Albania, even in districts where no trace of a Slavonic population exists, bears witness to the extensive Servian and Bulgarian immigrations in the early middle ages, but the original inhabitants gradually ousted or assimilated the invaders.
However adequate these identifications may seem, the persistence of an independent clan or tribe of Cherethites-Cretans to the close of the 7th century would imply an unbroken chain of nearly six hundred years, unless, as is inherently more probable, later immigrations had occurred within the interval.
Eberian influence in the south-west, Ligurian on the shores of the Mediterranean, Germanic immigrations from east of the Rhine and Scandinavian immigrations in the north-west have tended to produce ethnographical diversities which ease of intercommunication and other modern conditions have failed to obliterate.
Subsequently the Dorian element became greatly strengthened by fresh immigrations from the Peloponnesus, and during the historical period all the principal cities of the island were either Dorian colonies, or had adopted the Dorian dialect and institutions.
