Mongol Empire The Mongol Empire (Mongolian: "Mongolyn Ezent Güren"    ; Mongolian Cyrillic: Монголын эзэнт гүрэн; ] ; 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 Eastern 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.
Khanates of the Caucasus The Khanates of the Caucasus, or Azerbaijani khanates or Persian khanates, were various principalities established by Persia (Iran) on their territories in the Caucasus (modern-day Azerbaijan Republic, Armenia, Georgia and Dagestan) from the late Safavid to the Qajar dynasty. The Khanates were mostly ruled by Khans of Turkic (Azeri) origin and were vassals and subjects of the Iranian shah (King). Persia permanently lost a part of these khanates to Russia as a result of the Russo-Persian Wars in the course of the 19th century, while the others were absorbed into Persia.
