About Chairacha

Lived 1499 – 1546 (aged 46–47). Chairacha was a Thai sovereign.

Chairachathirat (, ), or Chai and drove the Burmese back. The Portuguese were then allowed to build a church near the Takhian Canal to practice their religion.

Sukhothai nobles Chairacha appointed his brother Prince Thianracha (later Maha Chakkrapat) as the Uparaja but did not grant him the title of King of Sukhothai as Chairacha was trying to unite the two kingdoms by reducing the power of Sukhothai nobles. He also called the Sukhothai nobles to Ayutthaya to move them from their base at Pitsanulok and made Ayutthaya the sole center of authority.

Mysterious death Though not having a son by a queen, Chai did have one, Yodfa, from Lady Sudachan, his favorite Chao Chom. However, she had a secret lover, Worawongsathirat, an officer of the Guards. Returning from the north, Chai became ill and died, and suspicion fell on Lady Sudachan. Her eleven-year-old son, Yodfa, became king in 1546. Chai's half brother, Prince Thianracha, became regent but entered a monastery to escape the ensuing power struggle. Sudachan became pregnant by Worawongsathirat and Yodfa was soon murdered. Khun Worawongsa assumed power. Khun Piren, and other retired officers, then ambushed the king and queen, and placed Thianracha on the throne in 1549.
