European contact and trade started in the early-16th century, with the envoy of Portuguese duke Afonso de Albuquerque in 1511, Portugal became an allied and ceded some soldiers to King Rama Thibodi II. The Portuguese were followed in the 17th century by the French, Dutch, and English. Rivalry for supremacy over Chiang Mai and the Mon people pitted Ayutthaya against the Burmese Kingdom. Several wars with its ruling dynasty Taungoo Dynasty starting in the 1540s in the reign of Tabinshwehti and Bayinnaung were ultimately ended with the capture of the capital in 1570. Then was a brief period of vassalage to Burma until Naresuan proclaimed independence in 1584.
