Duchy of Trakai

1337 CE – 1413 CE (approx.) · capital Trakai

The western half of medieval Lithuania, ruled by Kestutis and Vytautas from the island castle of Trakai.

Origins

Trakai, west of Vilnius among lakes, became the seat of Kestutis, son of Gediminas, in the late 1330s. After 1345 Lithuania was effectively shared between Algirdas in Vilnius and Kestutis in Trakai, who governed the western lands including Samogitia and led the defence against the Teutonic Order.

Rule and society

The duchy bore the brunt of the crusaders' raids from Prussia, and Kestutis fought them for almost fifty years. Trakai's castles became seats of power and residence. Vytautas brought Karaite and Tatar settlers to the town, whose Karaite community still lives there. The duchy had its own court and nobility, closely tied to the grand duke.

Decline and legacy

After Algirdas died, his son Jogaila fought Kestutis, who was killed in captivity at Kreva in 1382. Kestutis's son Vytautas regained Trakai and later became grand duke. In 1413 the Union of Horodlo turned the duchy into the Trakai Voivodeship of the Grand Duchy of Lithuania.
