One-party state

A government is the system or group of people governing an organized community, generally a state.

In the case of its broad associative definition, government normally consists of legislature, executive, and judiciary. Government is a means by which organizational policies are enforced, as well as a mechanism for determining policy. In many countries, the government has a kind of constitution, a statement of its governing principles and philosophy.

In the Soviet Union, a Union Republic (Russian: Сою́зная Респу́блика, romanized: Soyúznaya Respúblika) or unofficially a Republic of the USSR was a constituent federated political entity with a system of government called a Soviet republic, which was officially defined in the 1977 constitution as "a sovereign Soviet socialist state which has united with the other Soviet republics to form the Union of Soviet Socialist Republics" and whose sovereignty is limited by membership in the Union. As a result of its status as a sovereign state, the Union Republic de jure had the right to enter into relations with foreign states, conclude treaties with them and exchange diplomatic and consular representatives and participate in the activities of international organizations (including membership in international organizations). The Union Republics were perceived as national-based administrative units of the Union of Soviet Socialist Republics (USSR).

The Soviet Union was formed in 1922 by a treaty between the Soviet republics of Byelorussia, Russian SFSR (RSFSR), Transcaucasian Federation, and Ukraine, by which they became its constituent republics of the Union of Soviet Socialist Republics (Soviet Union). For most of its history, the USSR was a one-party state led by the Communist Party of the Soviet Union. Key functions of the USSR were highly centralized in Moscow until its final years, despite its nominal structure as a federation of republics; the light decentralization reforms during the era of perestroika (reconstruction) and glasnost (voice-ness, as in freedom of speech) conducted by Mikhail Gorbachev as part of the Helsinki Accords are cited as one of the factors which led to the dissolution of the USSR in 1991 as a result of the Cold War and the creation of the Commonwealth of Independent States.

The Socialist Federal Republic of Yugoslavia (commonly abbreviated as SFRY or SFR Yugoslavia), known from 1945 to 1963 as the Federal People's Republic of Yugoslavia, commonly referred to as Socialist Yugoslavia or simply Yugoslavia, was a country in Central and Southeast Europe. It was established in 1945, following World War II, and lasted until 1992, dissolving amid the onset of the Yugoslav Wars. Spanning an area of 255,804 square kilometres (98,766 sq mi) in the Balkans, Yugoslavia was bordered by the Adriatic Sea and Italy to the west, Austria and Hungary to the north, Bulgaria and Romania to the east, and Albania and Greece to the south. It was a one-party socialist state and federation governed by the League of Communists of Yugoslavia, and had six constituent republics: Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Serbia, and Slovenia. Within Serbia was the Yugoslav capital city of Belgrade as well as two autonomous Yugoslav provinces: Kosovo and Vojvodina.

The country emerged as Democratic Federal Yugoslavia on 29 November 1943, during the second session of the Anti-Fascist Council for the National Liberation of Yugoslavia midst World War II in Yugoslavia. Recognised by the Allies of World War II at the Tehran Conference as the legal successor state to Kingdom of Yugoslavia, it was a provisionally governed state formed to unite the Yugoslav resistance movement. Following the country's liberation, King Peter II was deposed, the monarchical rule was ended, and on 29 November 1945, the Federal People's Republic of Yugoslavia was proclaimed. Led by Josip Broz Tito, the new communist government sided with the Eastern Bloc at the beginning of the Cold War but pursued a policy of neutrality following the 1948 Tito–Stalin split; it became a founding member of the Non-Aligned Movement, and transitioned from a command economy to market-based socialism. The country was renamed Socialist Federal Republic of Yugoslavia in 1963.

Pol Pot (born Saloth Sâr; 25 May 1925 – 15 April 1998) was a Cambodian politician, revolutionary, and dictator who ruled the communist state of Democratic Kampuchea from 1975 until his overthrow in 1979. During his reign, his administration oversaw mass atrocities and he is widely believed to be one of the most brutal despots in modern world history. Ideologically a Maoist and Khmer ethnonationalist, Pot was a leader of Cambodia's Communist movement, known as the Khmer Rouge, from 1963 to 1997. He served as General Secretary of the Communist Party of Kampuchea from 1963 to 1981, during which Cambodia was converted into a one-party state. Between 1975 and 1979, the Khmer Rouge perpetrated the Cambodian genocide, in which an estimated 1.5–2 million people died—approximately one-quarter of the country's pre-genocide population. In December 1978, Vietnam invaded Cambodia to remove the Khmer Rouge from power. Within two weeks Vietnamese forces occupied most of the country, ending the genocide and establishing a new Cambodian government, with the Khmer Rouge restricted to the rural hinterlands in the western part of the country.

Born to a prosperous farmer in Prek Sbauv, French Cambodia, Pol Pot was educated at some of Cambodia's most elite schools. Arriving in Paris in October 1949 on an academic scholarship, he later joined the French Communist Party in 1951 while studying at École française de radioélectricité. Returning to Cambodia in 1953, he involved himself in the Khmer Viet Minh organisation and its guerrilla war against King Norodom Sihanouk's newly independent government. Following the Khmer Viet Minh's 1954 retreat into North Vietnam, Pol Pot returned to Phnom Penh, working as a teacher while remaining a central member of Cambodia's Marxist–Leninist movement. In 1959, he helped formalise the movement into the Kampuchean Labour Party, which was later renamed the Communist Party of Kampuchea (CPK). To avoid state repression, in 1962 he relocated to a jungle encampment and in 1963 he became the CPK's leader. In 1968, he relaunched the war against Sihanouk's government. After Lon Nol ousted Sihanouk in a 1970 coup, Pol Pot's forces sided with the deposed leader against the new government, which was bolstered by the United States military. Aided by the Viet Cong militia and North Vietnamese troops, Khmer Rouge forces advanced and controlled all of Cambodia by 1975.

A semi-presidential republic, or dual executive republic, is a republic in which a president exists alongside a prime minister and a cabinet, with the latter of the two being responsible to the legislature of the state. It differs from a parliamentary republic in that it has an executive president independent of the legislature; and from the presidential system in that the cabinet, although named by the president, is responsible to the legislature, which may force the cabinet to resign through a motion of no confidence.

While the Weimar Republic (1919–1933) and Finland (from 1919 to 2000) exemplified early semi-presidential systems, the term "semi-presidential" was first introduced in 1959, in an article by the journalist Hubert Beuve-Méry, and popularized by a 1978 work written by the political scientist Maurice Duverger. Both men intended to describe the French Fifth Republic (established in 1958).

Francoist Spain (Spanish: España franquista; English: pronounced Franco-ist), also known as the Francoist dictatorship (dictadura franquista), or Nationalist Spain (España nacionalista), and Falangist Spain (España falangista), was the period of Spanish history between 1936 and 1975, when Francisco Franco ruled Spain after the Spanish Civil War with the title Caudillo. After his death in 1975, Spain transitioned into a democracy. During Franco's rule, Spain was officially known as the Spanish State (Estado Español). The informal term "Fascist Spain" is also used, especially before and during World War II.

During its existence, the nature of the regime evolved and changed. Months after the start of the Civil War in July 1936, Franco emerged as the dominant rebel military leader and he was proclaimed head of state on 1 October 1936, ruling over the territory which was controlled by the Nationalist faction. In 1937, Franco became an uncontested dictator and issued the Unification Decree which merged all of the parties which supported the rebel side, turning Nationalist Spain into a one-party state under the FET y de las JONS. The Spanish Natioanlists received crucial support from Nazi Germany, Fascist Italy and Estado Novo Portugal, allowing them to win the civil war over the Spanish Republicans. The end of the Civil War in 1939 brought the extension of the Franco rule to the whole country and the exile of Republican institutions. The Francoist dictatorship originally took a form described as, "fascist or quasi-fascist", "fascistized", "para-fascist", "semi-fascist", or a strictly fascist regime, showing clear influence of fascism in fields such as labor relations, the autarkic economic policy, aesthetics, the single-party system, and totalitarian control of public and private life. As time went on, the regime opened up and became closer to developmental dictatorships and abandoned the radical fascist ideology of Falangism, although it always preserved residual fascist trappings and a "major radical fascist ingredient."

The Mongolian People's Republic (MPR) was a socialist state in Central and East Asia that existed from 1924 to 1992. A one-party state ruled by the Mongolian People's Revolutionary Party, it occupied the historical region of Outer Mongolia and functioned as a satellite state of the Soviet Union for its entire history. Geographically positioned between the Soviet Union and China, the MPR became the world's second socialist state. It is the predecessor of the modern state of Mongolia.

The state was established in 1924 following the Mongolian Revolution of 1921, which was supported by the Soviet Red Army. Under the rule of Khorloogiin Choibalsan, the government aligned closely with Soviet policies, undertaking Stalinist repressions from 1937 to 1939 that resulted in the deaths of over 20,000 people, including the near-total destruction of the country's Buddhist clergy. The MPR's army fought alongside the Soviets in the 1939 Battles of Khalkhin Gol against Japan, and its independence was formally recognized by China after a 1945 referendum.

The Nationalist government, Nationalist regime and Nationalist China, officially the National Government of the Republic of China, refer to the government of the Republic of China from 1 July 1925 to 20 May 1948, led by the nationalist Kuomintang (KMT) under Chiang Kai-shek.

Following the outbreak of the Xinhai Revolution, revolutionary leader Sun Yat-sen was elected to be China's provisional president and founded the Provisional Government of the Republic of China. To preserve national unity, Sun ceded the presidency to military strongman Yuan Shikai, who established the Beiyang government. After a failed attempt to install himself as Emperor of China, Yuan died in 1916, leaving a power vacuum which resulted in China being divided into several warlord fiefs and rival governments. They were nominally reunified in 1928 under the Nanjing-based government led by Chiang Kai-shek, which after the Northern Expedition initially governed the country as a one-party state under the Kuomintang, and was subsequently given international recognition as the legitimate representative of China, with Chiang as a de facto leader of the country under a military dictatorship. The Nationalist government would then experience many further challenges such as the Second Sino-Japanese War, and the Chinese Civil War. The government was in place until it was replaced by the current Government of the Republic of China in the newly promulgated Constitution of the Republic of China of 1947.

Slovakia, officially the (First) Slovak Republic, and from 14 March until 21 July 1939 officially known as the Slovak State (Slovak: Slovenský štát), was a partially recognized clerical fascist client state of Nazi Germany which existed between 14 March 1939 and 4 April 1945 in Central Europe. The Slovak part of Czechoslovakia declared independence with German support one day before the German occupation of Bohemia and Moravia. It controlled most of the territory of present-day Slovakia, without its current southern parts, which were ceded by Czechoslovakia to Hungary in 1938. The puppet state was the first formally independent Slovak state in history. Bratislava was declared the capital city.

A one-party state governed by the far-right Hlinka's Slovak People's Party, the Slovak Republic is primarily known for its collaboration with Nazi Germany, which included sending troops to the invasion of Poland in September 1939 and the Soviet Union in 1941. In 1940, the country joined the Axis when its leaders signed the Tripartite Pact.

The Independent State of Croatia (Croatian: Nezavisna Država Hrvatska, NDH) was a World War II–era quasi-protectorate of Fascist Italy (1941–1943) and puppet state of Nazi Germany (1941–1945). It was established in parts of occupied Yugoslavia on 10 April 1941, after the invasion by the Axis powers. Its territory consisted mostly of modern-day Croatia and Bosnia and Herzegovina, as well as some parts of modern-day Serbia and Slovenia, but also excluded many Croat-populated areas in Dalmatia (until late 1943), Istria, and Međimurje regions (which today are part of Croatia).

During its entire existence, the NDH was governed as a one-party state by the fascist Ustaše organization. The Ustaše was led by its Poglavnik, Ante Pavelić. The regime targeted Serbs, Jews and Roma as part of a large-scale campaign of genocide, as well as anti-fascist or dissident Croats and Bosnian Muslims. According to Stanley G. Payne, "crimes in the NDH were proportionately surpassed only by Nazi Germany, the Khmer Rouge in Cambodia and several of the extremely genocidal African regimes." In the territory controlled by the NDH, between 1941 and 1945, there existed 22 concentration camps. The largest camp was Jasenovac. Two camps, Jastrebarsko and Sisak, held only children.
