Skanderbeg's rebellion in the context of "League of Lezhë"

Gjergj Kastrioti (c. 1405 – 17 January 1468), commonly known as Skanderbeg, was an Albanian nobleman and military leader who led the League of Lezhë in the Ottoman-Albanian Wars until his death. Skanderbeg is considered to be a major figure of medieval Albanian history and today is the national hero of Albania.

A member of the noble Kastrioti family, Skanderbeg was sent as a hostage to the Ottoman court. He graduated from the Enderun School and entered the service of the Ottoman sultan Murad II (r. 1421–1451) for the next twenty years. His rise through the ranks culminated in his appointment as sanjakbey of the Sanjak of Dibra in 1440. During the Battle of Nish in 1443, he deserted the Ottomans and became the ruler of Krujë and nearby areas extending from Petrelë to Modrič. In March 1444, he established the League of Lezhë, with support from local noblemen, and unified the Albanian principalities.

The Liberation of Krujë (Albanian: Çlirimi i Krujës) was the capture of the city of Kruje from the Ottoman Empire by Skanderbeg on 28 November 1443. It marks the start of Skanderbeg's rebellion and is an important event in Albanian history.
