Biography
Saw O (Burmese: စောအို, pronounced [sɔ́ ʔò]; also known as Saw Aw, စောအော) was king of Martaban from 1311 to 1323. Born in 1283 in Mottama, the port city central to his reign, he ruled over Hanthawaddy Pegu during a time of major political changes in mainland Southeast Asia. His rule is best known for making Martaban fully independent, ending its long-held ties to the Sukhothai kingdom to the north.
Saw O became king through the actions of his parents, Governor Min Bala of Myaungmya and Princess Hnin U Yaing, who led a coup against King Hkun Law and placed him on the throne in 1311. However, his real power was limited while his father was alive. It was only after Min Bala died in the mid-to-late 1310s that Saw O became a fully independent ruler, capable of managing his kingdom on his own.
Once in control, Saw O acted quickly to change Martaban's relationship with Sukhothai. In 1317 or 1318, he officially broke away from Sukhothai, rejecting its former rule over the kingdom. This move was backed by military campaigns that greatly expanded his territory. By 1321, he had taken Lamphun to the north and gained control of the Tenasserim coast to the south, greatly widening Martaban's reach.
Saw O was married to May Hnin Htapi, and his court in Martaban became a hub of Mon political culture at the time. He ruled until 1323, when he died after about twelve years as king. Although his reign was relatively short, the political changes he made reshaped the region's power and set important foundations for the development of the Hanthawaddy kingdom as a major power in Lower Burma.
Before Fame
Saw O was born in 1283 in Mottama, a strategically important port along the Gulf of Martaban. His early life was influenced by his parents' ambitions. His father, Governor Min Bala of Myaungmya, and mother, Princess Hnin U Yaing, were deeply involved in the politics of Lower Burma, where Mon-speaking regions were dealing with the declining Pagan Empire and the emerging Sukhothai kingdom.
Saw O became king through a planned coup by his parents against King Hkun Law, making him a figurehead while his father held the actual power. This setup gave Saw O the chance to learn about court administration and regional politics, though he didn't have full control. It wasn't until his father's death in the mid-to-late 1310s that he was able to rule independently, focusing on policies aimed at expansion and independence that defined his later reign.
