Maung O

Favored by the king and queen, he was granted the appanage of Salin, Saku and Thamyintone with the title of Thado Maha Thudhamma Yaza.

[4] Maung O was born to U Hlote, commander of a thousand-man cavalry regiment (later Thiha Kyawswa of Shwedaung) and Daw Nge in Phalangon.

[7] Maung O's rise to power was due to his sister Nanmadaw Me Nu becoming King Bagyidaw's favorite queen.

The king gave his brother-in-law Salin, Saku and Thamyintone in fief and granted him the title of great prince in 1823.

In the monarchic era, successive Burmese kings did not appoint ordinary individuals to the position of the Duke of Salin.

It is believed that only trusted individuals who held significance in the eyes of the king were granted appointments to govern the Salin province.

As a prince regent, he wielded significant power and had the authority to pass judgments within the royal parliament (Hluttaw).

After the disastrous First Anglo-Burmese War (1824–1826) left the country crippled, Bagyidaw became increasingly reclusive, afflicted by bouts of depression, and could not handle the administration of the state.

On 21 February 1837, troops on the order of Maung O raided the residence of Princess Pagan (Bagan), sister of Tharawaddy.
