Situated on the Indochinese peninsula, Cambodia is bordered by Thailand and Laos on the north and Vietnam on the east and south. The Gulf of Thailand is off the western coast. The country consists chiefly of a large l plain ringed by mountains; on the east is the Mekong River. The plain is centered around Lake Tonle Sap, which is a natural storage basin of the Mekong.

Most Cambodians consider themselves to be Khmers, whose Angkor Empire extended over much of Southeast Asia and reached its zenith between the 10th and 13th centuries. Subsequently, attacks by the Thai and Cham (from present-day Vietnam) weakened the empire ushering in a long period of decline. In 1863, the king of Cambodia placed the country under French protection; it became part of French Indochina in 1887. Following Japanese occupation in World War II, Cambodia became independent within the French Union in 1949 and fully independent in 1953. After a five-year struggle, Communist Khmer Rouge forces captured Phnom Penh in April 1975 and ordered the evacuation of all cities and towns; at least 1.5 million Cambodians died from execution, enforced hardships, or starvation during the Khmer Rouge regime under POL POT. A December 1978 Vietnamese invasion drove the Khmer Rouge into the countryside, led to a 10-year Vietnamese occupation, and touched off almost 13 years of civil war. The 1991 Paris Peace Accords mandated democratic elections and a ceasefire, which was not fully respected by the Khmer Rouge. UN-sponsored elections in 1993 helped restore some semblance of normalcy and the final elements of the Khmer Rouge surrendered in early 1999. Factional fighting in 1997 ended the first coalition government, but a second round of national elections in 1998 led to the formation of another coalition government and renewed political stability. The July 2003 elections were relatively peaceful, but it took one year of negotiations between contending political parties before a coalition government was formed. Nation-wide local elections are scheduled for 2007 and national elections for 2008.
