Lan Na and Lan Xang (1579)

No troubles arose when Queen Visuddhadevi of Lan Na, who had successfully kept the middle Tai country quiet for over 13 years, died on 2 January 1579. Bayinnaung's choice Nawrahta Minsaw, one of his sons, faced no problems taking over the Lan Na throne. When instabilities arose in Lan Xang, he took no chances. On 17 October 1579, he sent a sizable army (22,000 men, 1200 horses, 120 elephants), which faced no opposition. According to Laotian history, the vassal king of Lan Xang Maha Ouparat died in 1580, and Bayinnaung installed Sen Soulintha, the usurper whom he had kept in Pegu since 1574, as the successor. The Burmese chronicles make no mention of any change for the rest of the king's reign. The Chronicles' lone post-1579 entry on Lan Xang during his reign simply states that on 2 September 1581, the king commissioned a Buddhist pagoda in Lan Xang. The Chronicles say that the vassal king died in September/October 1588.
