The Mongol invasions of Europe occurred in the 13th century as part of the larger Mongol conquests led by Genghis Khan and his successors. The Mongols, known for their exceptional cavalry and military tactics, invaded Eastern Europe, reaching as far as Hungary and Poland by 1241. Their campaigns resulted in significant destruction and loss of life, as they employed brutal strategies to conquer cities. After the death of Genghis Khan, the Mongol Empire continued to expand under leaders like Ögedei Khan. The invasions ultimately halted due to various factors, including the death of Ögedei and the need to address internal conflicts within the empire. The Mongol presence in Europe left a lasting impact on trade and cultural exchanges.
