anthroponomy (including the last name Arbanasin, which literally means Albanian) were recorded. In 1350 the Serbian Tsar had donated a church and a number of serfs to the nobleman Ivanko around the region of Štip, and among the serfs a certain Gin Arbanasi is attested. In a text by Emperor John VI Kantakouzenos there is mention of nomadic Albanians present in the vicinity of Ohrid at around 1328. Andrea Gropa ruled the region and the city of Ohrid as an ally of King of Serbia Vukašin Mrnjavčević until Vukašin's death in 1371, with Andrea beginning a rivalry with his son, Prince Marko. Ruling as an independent ruler since the time of Vukašin, Andrea became de jure independent from Prince Marko in 1371 and was referred to as Župan and Gospodar of Ohrid (Lord of Ochrid). He joined the Albanian ruler and noble Andrea II Muzaka, and managed to take Kostur, Prilep and all Dibër region from Marko by that year. During Andrea's reign, the Gropa family forged their own coins. Albanian noble families controlled swathes of land in North Macedonia during different historical periods within the Middle Ages. The Gropa family ruled the regions between Pogradec, Ohrid and Debar during the 12th — 14th centuries. The presence of Albanians within modern-day North Macedonia is attested to by Serbian kings of the Middle Ages. In 1330, Stefan Dečanski explicitly mentioned the presence of Albanians and the Albanian names of villages in Kosovo, particularly in the district of Prizren, as well as within the district of Skopje. Between 1348 and 1353, Albanians are mentioned by Stefan Dušan as farmers and soldiers in the district of Tetovo and frequenters of the Fair of Saint George held in the vicinity of Skopje. In fact, entire Albanian villages were gifted by Serbian kings, especially by Stefan Dušan, as presents to the Serbian monastery of Tetovo, as well as to the monasteries of Prizren and Deçan. In the Middle Ages, Dibër was part of the Principality of Kastrioti ruled by the royal Kastrioti family with Gjon Kastrioti on the Albanian throne. After the death of Gjon Kastrioti in 1437, the eastern region was annexed by the Ottomans and became seat of the Sanjak of Dibra. Skanderbeg carried out several military actions in the territory of modern-day North Macedonia during his rebellion against the Ottoman Turks, such as the Battle of Oranik and the Battle of Ohrid.
