Title:
Genghis_Khan

Context:
Börte had three more sons, Chagatai (1187—1241), Ögedei (1189—1241), and Tolui (1190–1232). Genghis Khan also had many other children with his other wives, but they were excluded from the succession. While the names of sons were documented, daughters were not. The names of at least six daughters are known, and while they played significant roles behind the scenes during his lifetime, no documents have survived that definitively provide the number or names of daughters born to the consorts of Genghis Khan.

Question:
How many names of Ghengis Khan's daughters are known?

six
