Lan Xang
Prince Nokeo Koumane had been held in the Taungoo court for sixteen years, and by 1591 was about twenty years old. The sangha in Lan Xang sent a mission to King Nandabayin asking for Nokeo Koumane to be returned to Lan Xang as a vassal king. In 1591 he was crowned in Vientiane, gathered an army and marched to Luang Prabang where he reunited the cities, declared Lan Xang independence and cast off any allegiance to the Toungoo Empire. King Nokeo Koumane then marched toward Muang Phuan and then to the central provinces reuniting all the former territories of Lan Xang.
