In 1308 the government moved to Danylo's grandchildren - Andrew and Lev II, who started the new struggle against the Golden Horde allied with the Teutonic knights and princes of Mazowia. However, after their death the last monarch Yuri II again had to claim himself as the Golden Horde vassal. He was murdered in 1340 and his death gave the rise to Poland and Lithuania (the neighbors who had a dynastic right for the throne of Rus) to start a war for the Halycian-Volyn heritage. In 1392 Galicia, with Belz and Chelm Lands were finally icorporated to the Kingdom of Poland and Volhynia to the Grand Duchy of Lithuania.
