After the fall of Kyivan State, the political, economic and cultural center of Ukrainian lands was transferred to the Halycian-Volyn Land. In 1245 Prince Danylo of Halych had to admit his dependence on the Golden Horde. Hoping to get help from Catholic Europe in his the struggle for independence, he also made a secret alliance with Poland, Hungary, Masovia and the Teutonic Knights. In 1253 he received the crown from Pope Innocent IV and became a King of Rus. In 1259, due to the lack of military aid from the West, the king was forced to re-recognize the supremacy of the Horde. His successor, Lev I had to take part in theTartar campaigns against Poland and Lithuania.
