According to the Camadevivamsa and Jinakalamali chronicles, the city was founded by a hermit named Suthep in 661 AD, and the Mon ruler of Lavo Kingdom (present-day Lopburi) sent his daughter Jamadevi to become its first queen. However, this date is now considered as too early, and the actual beginning is placed at around 750 AD.[citation needed] At that time, most of what is now central Thailand was under the rule of various Mon city states, known collectively as the Dvaravati kingdom. Queen Jamadevi gave birth to twins, the older succeeding her as the ruler of Lamphun, and the younger becoming ruler of neighboring Lampang.
