United Nations Transitional Authority in Cambodia in the context of "United Nations Administered Cambodia"

The United Nations Security Council (UNSC) is one of the six principal organs of the UN system and is the primary organ charged with ensuring international peace and security. Its powers as outlined in the UN Charter include authorizing military action, establishing peacekeeping operations, recommending the admission of new members to the UN General Assembly, approving any changes to the Charter, and enacting international sanctions. Chapter VII of the UN Charter gives the Security Council the power to identify threats to international peace and security and to authorize responses, including the use of force. Security Council resolutions adopted under Chapter VII are binding on UN members and are therefore a source of international law. The Security Council is the only UN body with the authority to issue resolutions that are binding on its member states.

Like the United Nations as a whole, the Security Council was created after World War II in 1945 in the hope of preventing future wars and maintaining world peace, as the League of Nations had been formed following World War I. It held its first session on 17 January 1946 but was largely paralyzed in the following decades by the Cold War between the United States and the Soviet Union (and their allies). Nevertheless, it authorized military interventions in the Korean War, the Congo Crisis, and peacekeeping missions in Cyprus, West New Guinea, and the Sinai Peninsula. With the collapse of the Soviet Union, UN peacekeeping efforts increased dramatically in scale, with the Security Council authorizing major military and peacekeeping missions in Kuwait, Namibia, Cambodia, Bosnia and Herzegovina, Rwanda, Somalia, Sudan, and the Democratic Republic of the Congo.

Cambodia, officially the Kingdom of Cambodia, is a country in Mainland Southeast Asia. It is bordered by Thailand to the northwest, Laos to the north, and Vietnam to the east, and has a coastline along the Gulf of Thailand in the southwest. It spans an area of 181,035 square kilometres (69,898 square miles), dominated by a low-lying plain and the confluence of the Mekong river and Tonlé Sap, Southeast Asia's largest lake. It is dominated by a tropical climate. Cambodia has a population of about 17 million people, the majority of which are ethnically Khmer. Its capital and most populous city is Phnom Penh, followed by Siem Reap and Battambang.

In 802 AD, Jayavarman II declared himself king, uniting the warring Khmer princes of Chenla under the name "Kambuja". This marked the beginning of the Khmer Empire. The Indianised kingdom facilitated the spread of first Hinduism and then Buddhism to Southeast Asia and undertook religious infrastructural projects throughout the region, the most famous of which is Angkor Wat. In the 15th century, it began a decline in power until, in 1863, Cambodia became a French protectorate. Following Japanese occupation during World War II, Cambodia declared independence from France in 1953. The Vietnam War embroiled the country in civil war during the 1960s, culminating in a 1970 coup which installed the US-aligned Khmer Republic and the takeover of the communist Khmer Rouge in 1975. The Khmer Rouge ruled the country and carried out the Cambodian genocide from 1975 until 1979, until they were ousted during the Cambodian–Vietnamese War. Peace was restored by the 1991 Paris Peace Accords and subsequent United Nations peacekeeping mission, establishing a new constitution, holding the 1993 general election, and ending long-term insurgencies. The 1997 coup d'état consolidated power under Prime Minister Hun Sen and the Cambodian People's Party (CPP).

The Paris Peace Agreements (Khmer: សន្ធិសញ្ញាសន្តិភាពទីក្រុងប៉ារីស ឆ្នាំ១៩៩១; French: Accords de paix de Paris), officially the Comprehensive Cambodian Peace Agreements, was signed on 23 October 1991 and marked the official end of the Cambodian–Vietnamese War and the Third Indochina War. The agreement led to the deployment of the first UN peacekeeping mission (the United Nations Transitional Authority in Cambodia) since the Cold War and the first occasion in which the United Nations took over as the government of a state. The agreement was signed by nineteen countries.

The Paris Peace Agreements were the following conventions and treaties:

General elections were held in Cambodia between 23 and 28 May 1993. The result was a hung parliament with the FUNCINPEC Party being the largest party with 58 seats. Voter turnout was 89.56%. The elections were conducted by the United Nations Transitional Authority in Cambodia (UNTAC), which also maintained peacekeeping troops in Cambodia throughout the election and the period after it.

As of 2024, the 1993 general elections were the last to be won by a party other than the Cambodian People's Party, which began to dominate Cambodian politics from 1998.

After decades of conflict, Cambodia's current form of government began in 1993 with the restoration of the monarchy and end of the State of Cambodia and the United Nations Transitional Authority after general elections were held. Since 1993, the Cambodian People's Party have consistently been in government, and consolidated power in a 1997 coup d'état. Hun Sen was prime minister until transfer of power to his son, Hun Manet, in 2023.

The National United Front for an Independent, Neutral, Peaceful and Cooperative Cambodia, commonly referred to as FUNCINPEC, is a royalist political party in Cambodia. Founded in 1981 by Norodom Sihanouk, it began as a resistance movement against the People's Republic of Kampuchea (PRK) government. In 1982, it formed a resistance pact with the Coalition Government of Democratic Kampuchea (CGDK), together with the Khmer People's National Liberation Front (KPNLF) and the Khmer Rouge. It became a political party in 1992.

FUNCINPEC was one of the signatories of the 1991 Paris Peace Accords, which paved the way for the formation of the United Nations Transitional Authority in Cambodia (UNTAC). The party participated in the 1993 general elections organised by UNTAC. It won the elections, and formed a coalition government with the Cambodian People's Party (CPP), with which it jointly headed. Norodom Ranariddh, Sihanouk's son who had succeeded him as the party president, became First Prime Minister while Hun Sen, who was from the CPP, became Second Prime Minister.
