Overview

This lecture covers the Mongol invasion of Hungary in the 13th century, including the rise of the Mongol Empire, the invasion's course, its devastating impact, and Hungary’s subsequent recovery under King Béla IV.

The Rise of the Mongol Empire

• Temüjin (Genghis Khan) unified Mongol tribes and created a military state.
• Mongol society was originally nomadic, with clans led by khans.
• Genghis Khan’s reforms replaced tribal structure with organized military units.
• The Mongols expanded rapidly, conquering parts of China, India, and Russia with disciplined cavalry tactics.
• After Genghis’s death, his son Ögedei ruled, dividing the empire among Genghis's sons as semi-autonomous regions (Ulus).
• Batu, Genghis’s grandson, lead western expansion, culminating in the creation of the Golden Horde.

Early Warnings and Preparations in Hungary

• Hungarian King Béla IV dismissed his father's advisers and centralized royal power.
• Dominican friar Julianus warned Béla IV of the Mongol threat after visiting Magyars near the Volga.
• The Cumans, fleeing Mongols, were allowed into Hungary, worsening tensions with the native nobility.

The Mongol Invasion of Hungary

• Mongols invaded Hungary in 1241 from three directions, defeating Hungarian forces at Verecke Pass and Vác.
• Distrust of the Cumans led to their leader’s death and the Cumans abandoning Hungary.
• Hungary, isolated, faced the Mongol invasion alone.

• King Béla IV escaped west but received no European aid.

Aftermath and Devastation
