How did diversity both provide benefits and create problems for Mongol rulers?

Diversity within the Mongol Empire provided significant benefits by facilitating trade, cultural exchange, and the integration of various administrative practices from conquered peoples, which helped maintain a vast and complex empire. However, it also created problems, as the Mongol rulers faced challenges in managing the different customs, languages, and loyalties of diverse populations, leading to tensions and occasional rebellions. Balancing these diverse interests often required diplomatic skill and military might, straining resources and complicating governance. Ultimately, while diversity contributed to the empire's richness, it also posed risks to unity and stability.
