Mandukhai Khatun (1449-c. 1510) — **"Manduhai the Wise"** — was the **Mongol Empress who reunified the fractured Mongol nation in the late 15th century**. Widowed young, she adopted the seven-year-old prince Batu Möngke (later Dayan Khan), married him as he grew, **personally led armies into battle while pregnant**, and rebuilt the Borjigin dynasty's authority over all the Mongol tribes.
**Subject of the Mongolian national film *Mandukhai the Wise Queen* (1988).**
Mandukhai reduces to nine — the number of Mongol reunifier.
