Emperor Monmu
Genmei became the consort ("nyōgo") of Crown Prince Kusakabe no Miko, who was the son of Emperor Tenmu and Empress Jitō. After the death of their son Emperor Monmu in 707, she acceded to the throne. At least one account suggests that she accepted the role of empress because Emperor Mommu felt his young son, her grandson, was still too young to withstand the pressures which attend becoming emperor.
