Two Mon brothers Thamala and Wimala from Thaton. first founded the city about 825 A.D. In 13th century A.D. The site, which was then on the Gulf of Martaban had already been earmarked as the location of a great city by Gautama. Bago was made the capital of the Mon Kingdom and it came to be known as Hansavati (Hanthawaddy). It was also the seaport of ancient Mon kings. Then it became the Second Myanmar Empire founded by King Bayinnaung.
