During the Burmese–Siamese War (1568–1569), the Burmese under King Bayinnaung gained control over Tavoy, Tanintharyi and the whole coast from the Siamese. King Naresuan of Siam regained the coast in 1592. Later King Anaukpetlun of the Burmese Toungoo dynasty retook Tavoy. The Tenasserim Coast then became separated into two portions; the northern Tavoy portion under Burmese domination and the southern part, comprising Tanintharyi and Mergui, under Siamese control. This power balance existed for about one hundred years.
