How did the political structure of the Mongol Empire change after the death of Genghis Khan?

The political structure of the Mongol Empire after the death of Genghis Khan did indeed remain largely unchanged under his descendants, particularly in the immediate years following his passing. Genghis Khan established a highly organized political and military structure that continued to function effectively after his death in 1227. His sons and grandsons maintained the empire through a system of khanates, largely preserving the centralized authority that Genghis Khan had implemented.

Under his heirs, especially Ogedei Khan, the empire experienced expansion and consolidation. The administrative systems and the hierarchical governance that were established during Genghis Khan's rule were upheld, allowing the vast territory to be managed more effectively. This continuity helped facilitate trade and communication across the empire, which was essential for maintaining control over the diverse regions and populations within Mongol territory.

While there were changes and challenges over time, particularly with the later fragmentation of the empire into different khanates, initially, the governance structures founded by Genghis Khan persisted as his descendants sought to build upon his legacy rather than abandon it.
