This map of Southeast Asia in the mid-16th century shows the major centers of power in the region prior to the arrival of Europeans. During this period, these kingdoms were constantly at war. Eventually the Kingdom of Ayutthaya (modern Thailand) expanded to the north and east, absorbing much of Lan Na and Lan Xang (modern Laos). Dai Viet (modern Vietnam) expanded to the south, taking over the remaining territory of the Kingdom of Champa and the southern tip of the Kingdom of Lovek (modern Cambodia). Toungoo evolved into modern Myanmar.
