- Mongol Invasion of Poland (1240–1241)
In late 1240 to 1241, the Mongol Empire launched its first major invasion of Poland to secure the flank of the main Mongol army attacking Hungary. The campaign culminated in the Battle of Legnica, where the Mongols defeated a combined force of Poles and allied military orders under Henry II the Pious. This neutralised any potential Polish assistance to King Béla IV of Hungary.
