Augusto Pinochet in the context of "Chilean Constitution of 1980"

A dictator is a political leader who possesses absolute power. A dictatorship is defined as a state ruled by a dictator. The word originated as the title of a Roman dictator elected by the Roman Senate to rule the republic in times of emergency. Like the terms "tyrant" and "autocrat", dictator came to be used almost exclusively as a non-titular term for oppressive rule. In modern usage, the term dictator is generally used to describe a leader who holds or abuses an extraordinary amount of personal power.

Dictatorships are often characterised by some of the following: suspension of elections and civil liberties; proclamation of a state of emergency; rule by decree; repression of political opponents; not abiding by the procedures of the rule of law; and the existence of a cult of personality centered on the leader. Dictatorships are often one-party or dominant-party states. A wide variety of leaders coming to power in different kinds of regimes, such as one-party or dominant-party states and civilian governments under a personal rule, have been described as dictators.

A military junta (/ˈhʊntə, ˈdʒʌntə/ ) is a system of government led by a committee of military leaders. The term junta means "meeting" or "committee" and originated in the national and local junta organized by the Spanish resistance to Napoleon's invasion of Spain in 1808. The term is now used to refer to an authoritarian form of government characterized by a politically dominant group of military officers.

An authoritarian military dictatorship ruled Chile for almost seventeen years, between 11 September 1973 and 11 March 1990. The dictatorship was established after the democratically elected socialist government of Salvador Allende was overthrown in a coup d'état backed by the United States on 11 September 1973. During this time, the country was ruled by a military junta headed by General Augusto Pinochet. The military used the breakdown of democracy and the economic crisis that took place during Allende's presidency to justify its seizure of power. The dictatorship presented its mission as a "national reconstruction". The coup was the result of multiple forces, including pressure from conservative groups, certain political parties, union strikes and other domestic unrest, as well as international factors.

The regime was characterized by the systematic suppression of political parties and the persecution of dissidents to an extent unprecedented in the history of Chile. Overall, the regime left over 3,000 dead or missing, tortured tens of thousands of prisoners, and drove an estimated 200,000 Chileans into exile. The dictatorship's effects on Chilean political and economic life continue to be felt. Two years after its ascension, neoliberal economic reforms were implemented in sharp contrast to Allende's leftist policies. The government was advised by the Chicago Boys, a team of free-market economists educated in the United States. Later, in 1980, the regime replaced the 1925 Constitution with a new constitution in a controversial referendum. This established a series of provisions that would eventually lead to the 1988 Chilean national plebiscite on October 5 of that year.

The Government Junta of Chile (Spanish: Junta de Gobierno de Chile) was the military junta established to rule Chile during the military dictatorship that followed the overthrow of President Salvador Allende in the 1973 Chilean coup d'état. The Government Junta was the executive and legislative branch of government until 17 December 1974, when Augusto Pinochet was formally declared President of Chile. After that date, it functioned strictly as a legislative body until the return to democracy in 1990.

A constitutional referendum was held in Chile on 11 September 1980. The proposed new constitution would replace the 1925 constitution, and was approved by over two-thirds of voters.

The referendum was controversial, as Chile was then being ruled by a military dictatorship, and it ensured that Augusto Pinochet would remain in power with a rule by decree until 1988, after which he was peacefully removed from power following a popular referendum.

The 1973 Chilean coup d'état (Spanish: Golpe de Estado en Chile de 1973) was a military overthrow of the socialist president of Chile Salvador Allende and his Popular Unity coalition government. Allende, who has been described as the first Marxist to be democratically elected president in a Latin American liberal democracy, faced significant social unrest, political tension with the opposition-controlled National Congress of Chile. On 11 September 1973, a group of military officers, led by General Augusto Pinochet, seized power in a coup, ending civilian rule.

During the air raids and ground attacks preceding the coup, Allende delivered his final speech, expressing his determination to remain at Palacio de La Moneda and rejecting offers of safe passage for exile. Although he died in the palace, the exact circumstances of Allende's death are still disputed, but it is generally accepted as a suicide. Following the coup, a military junta was established, and suspended all political activities in Chile and suppressed left-wing movements, such as the Communist Party of Chile and the Socialist Party of Chile, the Revolutionary Left Movement (MIR), and other communist and socialist parties. Pinochet swiftly consolidated power and was officially declared president of Chile in late 1974.
