As Srivijaya influence in the region declined, The Hindu Khmer Empire experienced a golden age during the 11th to 13th century CE. The empire's capital Angkor hosts majestic monuments—such as Angkor Wat and Bayon. Satellite imaging has revealed that Angkor, during its peak, was the largest pre-industrial urban centre in the world. The Champa civilisation was located in what is today central Vietnam, and was a highly Indianised Hindu Kingdom. The Vietnamese launched a massive conquest against the Cham people during the 1471 Vietnamese invasion of Champa, ransacking and burning Champa, slaughtering thousands of Cham people, and forcibly assimilating them into Vietnamese culture.
