The Mongol Empire of the 13th and 14th centuries was the largest contiguous empire in history. Originating in present-day Mongolia in East Asia, the Mongol Empire at its height stretched from the Sea of Japan to parts of Eastern Europe, extending northward into parts of the Arctic; eastward and southward into parts of the Indian subcontinent, attempted invasions of Southeast Asia, and conquered the Iranian Plateau; and westward as far as the Levant and the Carpathian Mountains.
