Gjergj Arianiti in the context of "League of Lezhë"

The term Albanian Principalities refers to a number of principalities (although they functioned more like a series of kingdoms) created in the Middle Ages in Albania and the surrounding regions in the western Balkans that were ruled by Albanian nobility. The 12th century marked the first Albanian principality, the Principality of Arbanon. It was later, however, in the 2nd half of the 14th century that these principalities became stronger, especially with the fall of the Serbian Empire after 1355. Some of these principalities were notably united in 1444 under the military alliance called League of Lezhë up to 1480 which defeated the Ottoman Empire in more than 28 battles. They covered modern day Albania, western and central Kosovo, Epirus, areas up to Corinth, western North Macedonia, southern Montenegro. The leaders of these principalities were some of the most noted Balkan figures in the 14th and 15th centuries such as Gjin Bua Shpata, Andrea II Muzaka, Gjon Zenebishi, Karl Topia, Andrea Gropa, Balsha family, Gjergj Arianiti, Gjon Kastrioti, Skanderbeg, Dukagjini family and Lek Dukagjini.

The Albanian–Ottoman Wars (1432–1479) were a series of wars and revolts against the rising Ottoman Empire by Albanian feudal lords. The wars and revolts took place in present-day Albania, Montenegro, Kosovo, North Macedonia and South Serbia. In this period, Albanians under the leadership of Gjergj Arianiti and especially later under Skanderbeg resisted the Ottomans under two Sultans in over 30 battles. Skanderbeg continued this resistance until his death in 1468, and the Albanians persevered for another 11 years before being defeated.

Andronika Arianiti, commonly known as Donika Kastrioti, (1428 – 1506) was an Albanian noblewoman and Lady of Albania from her marriage to Skanderbeg. She was the daughter of Gjergj Arianiti, an earlier leader in the ongoing revolt against the Ottomans, and Maria Muzaka, whose family ruled under the title of despots in the southern part of the country.

Gjon II Kastrioti (Italian: Ioanne Castrioto, Giovanni Castrioto; 1456 – 2 August 1514), was an Albanian prince and the son of Gjergj Kastrioti Skanderbeg, the Albanian national hero, and of Andronika Arianiti, daughter of Gjergj Arianiti. He was for a short time Lord of Krujë after his father's death, then Duke of San Pietro in Galatina (1485), Count of Soleto, Signore of Monte Sant'Angelo and San Giovanni Rotondo. In 1495, Ferdinand I of Naples gave him the title of the Signore of Gagliano del Capo and Oria. While in his early teens, he was forced to leave the country after the death of his father in 1468. He is also known for his role in the Albanian Rebellion of 1481–1484, when, after reaching the Albanian coast from Italy and settling in Himara, he led a rebellion against the Ottoman Empire. In June 1481, he supported forces of Ivan Crnojević to successfully recapture Zeta from the Ottomans. He was unable to re-establish the Kastrioti Principality and liberate Albania from the Ottomans, and he retired in Italy after three years of war in 1484.

The Albanian revolt of 1432–1436 (Albanian: Kryengritja Arbërore) was a series of conflicts between Albanian rebels and the Ottoman Empire during the early period of Ottoman rule in the region. Prompted by the replacement of large parts of the local nobility with Ottoman landowners, centralized governance, and the Ottoman taxation system, the population and the nobles, led principally by Gjergj Arianiti, revolted against the Ottomans.

During the early phases of the revolt, many land (timar) holders were killed or expelled. As it spread, the nobles, whose holdings had been annexed by the Ottomans returned to join the revolt and attempts to form alliances with the Holy Roman Empire were initiated. While the leaders of the revolt were successful in defeating successive Ottoman campaigns, they failed to capture many important towns of the sanjak of Albania. Protracted sieges like that of Gjirokastër, capital of the sanjak, gave the Ottoman army time to assemble large forces from other parts of the empire and to subdue the main revolt by the end of 1436. Ottoman forces conducted a number of massacres in the aftermath of the revolt.

Maria Muzaka was an Albanian princess from the Muzaka family. She was a daughter of Andrea III Muzaka and his wife Chiranna Zenevisi, Lady of Grabossa. From her marriage to Gjergj Arianiti, Maria had eight daughters, most notably of them were Andronika, Queen of Albania, and Saint Angjelina, Empress of Serbia.
