When did the Mongols invade Western Europe?

Having conquered the Volga region, Southern Russia, Kiev and the inheritance of Daniel of Galicia, the hordes of Batu Khan and Subudey moved to Europe. The main goal of the Mongols was Hungary. Under the patronage of the Hungarian king Bela the Fourth was Batu’s sworn enemy, the Polovtsian Khan Kotyan, who converted to Catholicism. Dividing the army, Batu went on two fronts to the Hungarian lands. Subedey defeated the Polovtsians on the Seret River and advanced to join the main Mongol forces. The Croatian and Hungarian regiments were defeated on the Shajo River. The Transdanubian Hungarian regions were at the mercy of the Mongol invaders. In the Western campaign of 1236 – 1242, Bulgaria, Croatia, Bosnia, Serbia and part of Hungary were conquered. The death of Khan Ogedei forced Batu to leave for his native steppes.
