Which characteristic aligns the Roman and Mongol Empires?

The characteristic that aligns the Roman and Mongol Empires is their status as large, powerful empires that controlled vast territories.

The Roman Empire, at its height, extended across Europe, North Africa, and parts of the Middle East, showcasing a sophisticated administrative structure and a diverse population under its rule. It established a legacy through its extensive road networks, legal systems, and cultural impacts across its provinces.

Similarly, the Mongol Empire, known for being the largest contiguous land empire in history, spanned much of Asia and into Eastern Europe. Under the leadership of Genghis Khan and his successors, the Mongols created a vast network of trade routes, including the Silk Road, facilitating commerce and cultural exchange across their territories.

Both empires exemplified military strength and strategic governance that enabled them to dominate large areas, incorporating various cultures and systems into their vast realms. In contrast, the other options do not accurately reflect characteristics of both empires, such as governance by democracies, reliance on maritime trade, or a sole focus on agricultural economies, which were more nuanced and varied across their respective histories.
