The Khmer Rouge reached Phnom Penh and took power in 1975. Led by Pol Pot, they changed the official name of the country to Democratic Kampuchea. The new regime modelled itself on Maoist China during the Great Leap Forward, immediately evacuated the cities, and sent the entire population on forced marches to rural work projects. They attempted to rebuild the country's agriculture on the model of the 11th century, discarded Western medicine, and destroyed temples, libraries, and anything considered Western.
