Erdeni Batur (in modern Mongolian: Эрдэнэбаатар, Erdenebaatar; Chinese: 巴圖爾琿台吉; d. 1653) was a Choros-Oirat prince generally considered to be the founder of the Dzungar Khanate, centered in the Dzungaria region, currently in north-westernmost part of China.
Erdenebaatar was the son of Khara Khula who was taishi (in modern Mongolian:тайж, taij, meaning "nobleman") of the dominant Choros tribe and the leader of the allied Four Oirat, collectively known as "Dzungars."
The Fifth Dalai Lama took note of the rising power and influence of the Dzungar Khanate and granted Erdeni Batur the title, "Khong Tayiji" (known in Chinese as Hong Taiji, or crown prince) for military support he provided Güshi Khan to topple the enemies of the Gelug sect.
His increased stature and the wide recognition the Dzungar Khanate received as a great power among Central Asian nomads led Erdenebaatar to call for a pan-Mongolian alliance in 1640.
To that end, a legal code was drafted, establishing a system of rules that governed the daily activities of all Mongols from the Volga River in southeastern Russia to present-day eastern Mongolia.
