In the early 13th century the Duchy of Turov became dependent of the Kingdom of Galicia–Volhynia. To liberate[clarification needed] itself from it, the dukes of Turov cooperated more and more with the Grand Duchy of Lithuania. In the early 14th century the Duchy non-violently joined the Grand Duchy. By that time Hleb Narymunt, the son of Gediminas, was already ruler of Pinsk, while Turov and Haradok were still ruled by Rurikids. Later the territory of the Duchy became part of Brest Litovsk, Nowogródek, and Minsk Voivodeships.
