Queen Won Kyung, born to Min Je during the Goryeo period, came from a prestigious family of high-ranking officials. Married to Lee Bang Won, son of King Taejo, she supported her husband's ambitions to become King Taejong after his father bypassed him for the throne. As a kingmaker, she helped establish a new regime. However, their relationship soured after Lee Bang Won became king, took concubines, and sought to curb Queen Won Kyung's influence and that of her family.
