Lekė was an Albanian prince that inherited his father's, Pal Dukagjini, princedom when he died in 1446. His lands stretched in the north and northeast of Shkodėr, with Lezhė as its capital. They included lands in present-day Serbia, such as Zadrima and Ulpiana.
Lekė was educated in Venice and Shkodėr. He led the League of Lezha in 1444. He fought side-by-side Skanderbeg against the Turks, but they also fought against each other at times. However Lekė continued to fight against the Ottoman Empire until his death in 1481, sometimes besides the Venetians with the blessing of the papacy.
Overshadowed by Skanderbeg, Lekė Dukagjini is most well known for the set of laws ruling the highlands of northern Albania, known as the Kanuni. The set of laws was active in practice for a long time, but it was not gathered and codified until the late 19th century by Shtjefėn Gjeēov. The most infamous laws of Kanuni are those regulating blood feuds. Blood feuds have started once again in lawless northern Albania after the fall of communism in the early 1990s, having been outlawed for many years during the regime.
