Around 1230 the two main centers of Albanian settlements were around Devoll river in what is now central Albania and the other around the region known as Arbanon. Albanian presence in Croatia can be traced back to the beginning of the Late Middle Ages. In this period, there was a significant Albanian community in Ragusa with a number of families of Albanian origin inclusively the Sorgo family who came from the Cape of Rodon in central Albania, across Kotor in eastern Montenegro, to Dalmatia. By the 13th century, Albanian merchants were trading directly with the peoples of the Republic of Ragusa which increased familiarity between Albanians and Ragusans. The upcoming invasion of Albania by the Ottoman Empire and the death of Skanderbeg caused many Christian Albanians to flee to Dalmatia and surrounding countries.
