The Mongol Empire ( Mongolian : Mongolyn Ezent Güren ; Mongolian Cyrillic : Монголын эзэнт гүрэн ; [ mɔŋɡ ɮˈiːŋ ɛt͡sˈɛnt ˈɡurəŋ ] also Орда ( `` Horde '' ) in Russian chronicles ) existed during the 13th and 14th centuries and was the largest contiguous land empire in history . Originating in the steppes of Central Asia , the Mongol Empire eventually stretched from Central Europe to the Sea of Japan , extending northwards into Siberia , eastwards and southwards into the Indian subcontinent , Indochina , and the Iranian plateau , and westwards as far as the Levant and Arabia .
