You have a test on medieval history and the Mongol conquests are a blur — Genghis Khan, his grandsons, the Rus, Legnica, the Golden Horde. Who was Batu Khan, and why does he matter? This guide cuts through the confusion.

Batu Khan was the grandson who inherited the western portion of the Mongol Empire and then expanded it in ways that shocked two continents. Between 1237 and 1242 he and his brilliant strategist Subutai dismantled the Russian principalities one by one, then drove deep into Poland and Hungary, defeating every army that stood against them. When they finally stopped, it wasn't because anyone beat them. The state Batu founded on the Volga — the Golden Horde — outlasted every other piece of the empire his grandfather built.

This TLDR study guide covers his entire story in roughly 15 focused pages: the Jochi inheritance crisis that shaped Batu's ambitions, the 1235 kurultai that launched the great western campaign, the systematic Mongol conquest of Russia from Ryazan to Kiev, the twin victories at Legnica and Mohi that panicked Latin Christendom, and the founding of Sarai as the Golden Horde's capital. It also gives you the historical debate — what scholars actually argue about Batu's role, his rivalry with the Great Khan Guyuk, and how his state shaped Russia for two centuries.
