How long did it take to conquer the mongolian empire?

The Mongolian Empire was established in the early 13th century, with Genghis Khan unifying the Mongol tribes around 1206. The empire expanded rapidly over the next few decades, reaching its peak by the mid-13th century. The conquest of vast territories, including parts of China, Central Asia, and Eastern Europe, took roughly 20 years, from the early 1200s to the 1240s. However, the full consolidation and governance of these regions continued for several decades afterward.
