Government Junta of Chile (1973) in the context of "Chilean transition to democracy"

Augusto José Ramón Pinochet Ugarte (25 November 1915 – 10 December 2006) was a Chilean military officer and politician who was the President of Chile from 1973 to 1990. From 1973 to 1981, he was the leader of the military junta, which in 1974 declared him President of Chile; in 1980, a referendum approved a new constitution confirming him in the office, after which he served as de jure president from 1981 to 1990. His time in office remains the longest of any Chilean ruler.

Augusto Pinochet rose through the ranks of the Chilean Army to become General Chief of Staff in early 1972 before being appointed its Commander-in-Chief on 23 August 1973 by President Salvador Allende. On 11 September 1973, Pinochet seized power in Chile in a military coup. The military had previously received financial and intelligence support from the United States, which favored the military coup that toppled Allende's democratically elected socialist Unidad Popular government and ended civilian rule. In December 1974, the ruling military junta appointed Pinochet Supreme Head of the nation by joint decree, although without the support of one of the coup's instigators, Air Force General Gustavo Leigh.

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.

Air General Gustavo Leigh Guzmán (September 19, 1920 – September 29, 1999) was a Chilean general, who represented the Air Force in the 1973 Chilean coup d'état and, for a time, in the ruling junta that followed. Leigh was forced out of the military government in 1978.

The Constitution of 1925 was the constitution in force in Chile between 1925 and 1973 when the Government Junta suspended it. In the 1920s Chile had a severe social and economic crisis that led to the loss of prestige for old ruling class, labeled oligarchy in Chilean historiography, and the rise of a more sensibilized populist government led by Arturo Alessandri. In 1924 Alessandri was outed in a coup, but was called back in 1925 to complete his mandate. Alessandri then used his presidency to draft a new constitution to replace the Constitution of 1833.

The constitution was approved by plebiscite by 134,421 voters on August 30 of 1925. Prominent features of the constitution were:
