The Mongolian monarchy refers to the historical system of governance in Mongolia, where kings and khans ruled over various tribes and territories. The most notable figure in this context is Genghis Khan, who united the Mongolian tribes in the early 13th century and established the Mongol Empire, which became one of the largest empires in history. After Genghis Khan, the monarchy continued with his descendants, who ruled over vast regions of Asia and Europe. The monarchy faced challenges from internal divisions and external invasions, leading to its decline. Eventually, the last Mongolian monarchy was abolished in the early 20th century, transitioning Mongolia to a republic.
