Mongol invasion of Europe

The Mongol invasion of Europe in the 13th century involved the destruction of East Slavic principalities, such as Kiev and Vladimir, the invasion of the Kingdom of Hungary (in the Battle of Mohi) and fragmentation of Poland (in the Battle of Legnica). The operations were masterminded by General Subutai and commanded by Batu Khan and Kadan, both grandsons of Genghis Khan. As a result of the successful invasions, many of the conquered territories would become part of the Golden Horde empire.
