Final answer:
The Mongol Empire was a dominant global power, connecting parts of the world and promoting trade during 1200-1450.
Step-by-step explanation:
The Mongol Empire was incredibly significant during 1200-1450. They created the largest contiguous empire in history, stretching from central Europe to the Pacific Ocean, about the size of the African continent. While they did not make technological breakthroughs or contribute much culturally, they connected parts of the world that had never been connected before and promoted trade along the caravan routes of Central Asia. Their military success and control over vast territories make them a major global power during this time period.
