The history of Cambodia spans over a thousand years, beginning with the powerful Khmer Empire (802–1431), which built the magnificent temples of Angkor, including Angkor Wat. Following the empire's decline, Cambodia experienced periods of decline and domination by neighboring Siam and Vietnam before becoming a French protectorate in 1863. The 20th century brought independence (1953), devastating civil war, and the brutal Khmer Rouge regime (1975–1979), under which nearly two million people died. Since the 1990s, Cambodia has rebuilt itself as a constitutional monarchy and emerging Southeast Asian economy. More Less
