Some scientists accept that it is settled by Bulgarian boyars who came with their peasants from the most western lands after the brilliant victory of Ivan Assen II at Klokotnitza on 9 Mart 1230 when he takes possession of the Arbanassi land. During the Middle Ages Bulgarians called Arbanassi Arbanashka zemia. Rakovski says that Ivan Assen married the daughter of the captured kir Theodor Komnin and because of her moved some Greek families in Arbanassi.

Granitski makes a translation of the guidance in Veliko Turnovo issued by Hamamdjiev in Tzarigrad. It says:" The village of Arbanassi is located half an hour from Veliko Turnovo, to the east where the Bulgarian boyars and important people lived in old times with 2000 citizens…" This renaissance teacher from Kotel most precisely defines not only the name but also the origin of the population "settled in old times by the Bulgarian boyars". Richer documents (copies and chronicle notes in church books) have remained from XVII - XVIII c. It shows that Arbanassi reaches its economic climax in the second half of the XVII c. and by the end of XVIII c. Then the village had 1000 households and its population consisted of the most eminent trade families. The main occupation of the population was stock-breeding. The occupations connected with them were also developed.
