Thihathu of Ava was king of Ava from 1421 to 1425. Though he opportunistically renewed the Forty Years' War with Hanthawaddy Pegu in 1422, Thihathu agreed to a peace treaty with Prince Binnya Ran in 1423. His subsequent marriage to Ran's sister Princess Shin Saw Pu helped keep the peace between the two kingdoms when Ran became king of Pegu in 1424.

Shin Sawbu was queen regnant of Hanthawaddy from 1454 to 1471. Queen Shin Sawbu is also known as Binnya Thau or Old Queen in Mon. Queen Shin Sawbu and Queen Jamadevi of Haripunjaya are the two most famous among the small number of queens who ruled in mainland Southeast Asia.
