Bago is the central city of Bago District in southern Myanmar (Burma). It was formerly known as Pegu. It was founded in the early 9th century by the Mon people and was the capital of the Phetgu dynasty from the late 14th century to the early 16th century. Later, it became the capital of the Taungoo dynasty, founded by the Burmese, and remained so until the early 17th century, after which it was repeatedly disputed by the Mon and the Burmese.
