The Khmer Empire dominated trade in Southeast Asia for centuries, starting as the early kingdom of Funan. By 800 CE the Khmer had expanded to become a powerful empire, reaching their peak around 1200 CE through trade and conquest. The Sailendra dynasty ruled Java and left behind the great Buddhist temple of Borobudur, blending Indian and Javanese influences before being overcome by the Srivijaya kingdom. Vietnam was less influenced by India, becoming an independent kingdom in 939 after being controlled by China under the Han dynasty.
