The Cambodian People's Party (CPP) is a Cambodian political party which has ruled the country since 1979. Founded in 1951, it was originally known as the Kampuchean People's Revolutionary Party (KPRP).
The national flag of Cambodia (ទង់ជាតិកម្ពុជា) or the Khmer national flag (ទង់ជាតិខ្មែរ) in its present form was originally adopted in 1989 and readopted in 1993, after the Constituent Assembly election in 1993 and restoration of the Cambodian monarchy.
The royal arms of Cambodia is the symbol of the Cambodian monarchy. They have existed in some form close to the one depicted since the establishment of the independent Kingdom of Cambodia in 1953. It is the symbol on the royal standard of the reigning monarch of Cambodia, currently King Norodom Sihamoni.

The Cambodian–Vietnamese War was an armed conflict between Democratic Kampuchea, controlled by Pol Pot's Khmer Rouge, and the Socialist Republic of Vietnam. The war began with repeated attacks by the Kampuchea Revolutionary Army on the southwestern border of Vietnam, particularly the Ba Chúc massacre which resulted in the deaths of over 3,000 Vietnamese civilians. On 23 December 1978, 10 out of 19 of the Khmer Rouge's military divisions opened fire along the border with Vietnam with the goal of invading the Vietnamese provinces of Đồng Tháp, An Giang and Kiên Giang. On 25 December 1978, Vietnam launched a full-scale invasion of Kampuchea, occupying the country in two weeks and removing the government of the Communist Party of Kampuchea from power. In doing so, Vietnam put an ultimate stop to the Cambodian genocide, which had most likely killed between 1.2 million and 2.8 million people — or between 13 and 30 percent of the country’s population. On 7 January 1979, the Vietnamese captured Phnom Penh, which forced Pol Pot and the Khmer Rouge to retreat back into the jungle near the border with Thailand.
The Khmer Krom are ethnically Khmer people living in or from the Mekong Delta, the south western part of Vietnam known in Khmer as Kampuchea Krom.

The Royal Cambodian Armed Forces is Cambodia's national military force. The Supreme Commander-in-Chief is King Norodom Sihamoni. Since 2018, General Vong Pisen has been the Commander-in-Chief of the RCAF as head of the Army, Navy, Air Force and the Gendarmerie. The armed forces operate under the jurisdiction of the Ministry of National Defence. Under the country's constitution, the RCAF is charged with protecting the sovereignty and territorial integrity of the Kingdom of Cambodia.
The Coalition Government of Democratic Kampuchea, renamed in 1990 to the National Government of Cambodia, was a coalition government in exile composed of three Cambodian political factions, namely Prince Norodom Sihanouk's FUNCINPEC party, the Party of Democratic Kampuchea and the Khmer People's National Liberation Front (KPNLF) formed in 1982, broadening the de facto deposed Democratic Kampuchea regime. For most of its existence, it was the internationally recognized government of Cambodia.
The name of Cambodia in Khmer is កម្ពុជា, officially ព្រះរាជាណាចក្រកម្ពុជា. This term derives from Sanskrit कम्बोजदेश, which means the "land of Kamboja".
Media in Cambodia is largely unregulated and includes radio, television and print media outlets. Private sector companies have moved into the media sector, which represents a change from years of state-run broadcasting and publishing.
"Dap Prampi Mesa Moha Chokchey" was the national anthem of Democratic Kampuchea from at least January 1976. Although the anthem may have been in use in the "liberated zone" much earlier, it was proclaimed the national anthem in article 18 of the Constitution of Kampuchea which was promulgated on 5 January 1976. Supposedly, the Khmer Rouge and/or Pol Pot himself wrote the piece, but its origin remains unknown.
Democratic Kampuchea was the official name of the Cambodian state from 1976 to 1979, under the totalitarian dictatorship of Pol Pot and the Communist Party of Kampuchea (CPK), commonly known as the Khmer Rouge. The Khmer Rouge's capture of the capital Phnom Penh in 1975 effectively ended the United States-backed Khmer Republic of Lon Nol.
The People's Republic of Kampuchea (PRK) was a partially recognised state in Southeast Asia which existed from 1979 to 1989. It was a satellite state of Vietnam, founded in Cambodia by the Vietnamese-backed Kampuchean United Front for National Salvation, a group of Cambodian communists who were dissatisfied with the Khmer Rouge due to its oppressive rule and defected from it after the overthrow of Democratic Kampuchea, Pol Pot's government. Brought about by an invasion from Vietnam, which routed the Khmer Rouge armies, it had Vietnam and the Soviet Union as its main allies.
Cambodia used the postage stamps of Indochina until the early 1950s. In 1949 Cambodia became an associated state of the French Union but gained independence in 1953 and left the Union in 1955.
The flag of Democratic Kampuchea was the national flag of Cambodia during the period of Khmer Rouge rule. It was adopted on 5 January 1976, upon the implementation of a new national constitution by the Khmer Rouge. It ceased being the Cambodian national flag on 7 January 1979, when Vietnamese forces captured the capital Phnom Penh and effectively ended the Khmer Rouge government. However, the flag was retained by the exiled, Khmer Rouge–led Coalition Government of Democratic Kampuchea, which was recognised by the United Nations. The design is a red field charged in the centre with a yellow silhouette of a three-towered temple. Although the silhouette resembles Angkor Wat, a nationally significant monument and a common motif on preceding Cambodian flags, Democratic Kampuchea's constitution did not specifically mention Angkor Wat.
The flag of the People's Republic of Kampuchea was a historical flag of Cambodia from 1979 to 1989, used during the Cambodian–Vietnamese War.
The flag of the Khmer Republic is one of the historical flags of Cambodia. It consists of a blue field with a red rectangle in the canton. The red rectangle bears the Angkor Wat silhouette. Three large white stars are aligned horizontally on the upper corner of the blue field.
"Anthem of the People's Republic of Kampuchea" was the national anthem of the People's Republic of Kampuchea from 1979 to 1992. It was composed by Keo Chinda and Chy Saopea. While Vietnam and most Communist governments recognized the People's Republic of Kampuchea during its existence, the Khmer Rouge, together with the monarchists and Khmer People's National Liberation Front, formed the Coalition Government of Democratic Kampuchea that continued to use the anthem of Democratic Kampuchea. It was this government-in-exile that was recognized by China, North Korea, Romania, and most Western Bloc governments and the United Nations; as such, many Western sources continued to list "Dap Prampi Mesa Moha Chokchey" as being the Cambodian national anthem until the restoration of the monarchy in 1993.
The Kingdom of Kampuchea was a short-lived puppet state of Imperial Japan, which existed from 9 March 1945 to 16 October 1945.
