In 1595, Pegu faced rebellions by various tributaries and royal princes. Naresuan planned a massive invasion of Pegu but the city was taken beforehand by the Lord of Toungoo, with the support of Arakan. The efforts to capture Toungoo failed in May 1600, and Naresuan decided to retreat. In Lanna, however, a conflict arose between Nawrahta Minsaw, the Burmese king of Lanna, and Phraya Ram, a Siamese-installed Lanna noble. Naresuan sent Ekathotsarot to claim the conflicts by dividing Lanna into two parts.
