Gjergj Arianiti was Skanderbeg's ally within the League of Lezhë before abandoning the alliance after the capture of Berat by the Ottomans in 1450.

However, his daughter married Skanderbeg and he remained officially part of the League of Lezhe, continuing to fight Ottomans successfully up to his death in 1462.

After 1423 he fell under Ottoman political influence and probably resided at the sultan's palace as hostage to secure loyalty of his tribesmen.

[1] Skanderbeg's Rebellion (1443–1468) Contemporaneous Campaigns (1447–1462) Resistance until the Fall of Shkodra (1468–1479) The Ottoman conquest of certain parts of southern Albania brought Ottoman legal, political, and economic systems into the country, influencing all nobles and threatening to destroy the feudal system and autonomy of the nobles.

Upon hearing of the rebellions, many Albanian political enemies of Gjergj, who had become sipahi returned from Edirne to Albania.

This victory further strengthened the Albanian cause and gave hope to the Europeans who feared a major Ottoman invasion.

The Byzantine chronicler, Chalcondyles, wrote: "In this battle, Arianit Komneni won a glorious victory."

Arianiti also destroyed a second army sent by Ali Beg, leaving hundreds dead in the valleys of Kuç all the way to Borsh.

The joyful states of Europe – Pope Eugene IV, Alfonso V, Emperor Sigsimund, Venice and Ragusa – promised aid.

Murad II felt compelled to tacitly grant him the area between Shkumbin and south of Vjosa river as his dominions and have a truce with him.

In August 1443 Arianiti again rebelled against Ottomans, probably urged by pope Eugene IV or instigated by the news of defeat of Sihàb ed-Dîn Pasa.

Skanderbeg eventually allied with Gjergj Arianit and some other nobles from Albania and Zeta through the League of Lezhë.

In May–July 1435 Bulgarian prince Fruzhin visited Albania and meat Arianiti the leaders of the revolt, on a secret diplomat mission of emperor Sigismund.

In 1451 after Alfonso signed the Treaty of Gaeta with Skanderbeg, he signed similar treaties with Gjergj Arianiti and other chieftains from Albania: Ghin Musachi, George Strez Balšić, Peter Spani, Pal III Dukagjini,[13] Thopia Musachi, Peter of Himara, Simon Zenevisi and Carlo Tocco.

In an open front, Mehmet II ordered movements into Albania to engage a group of Arianiti's warriors.

[clarification needed] Arianiti was the only Albanian leader to have two capitals: one near the coast in Kanina, and another near the eastern mountains in Sopot.

From his first marriage (c.1420s–1440s) with Maria Muzaka, Arianiti had the following issue: From Gjergj Arianiti's second marriage to Pietrina Francone (c.1440s) the following children were born: Later on Alphonse concluded similar treaties with George Aryaniti, Ghin Musachi, George Stresi Balsha, Peter Spani, Paul Ducaghini,...
