The territory of Chile has been populated since at least 3000 BC. By the 16th century, Spanish invaders began to raid the region of present-day Chile, and the territory was a colony from 1540 to 1818, when it gained independence from Spain. The country's economic development was successively marked by the export of first agricultural produce, then saltpeter and later copper. The wealth of raw materials led to an economic upturn, but also led to dependency, and even wars with neighboring states. Chile was governed during most of its first 150 years of independence by different forms of restricted government, where the electorate was carefully vetted and controlled by an elite.
Salvador Guillermo Allende Gossens was a Chilean socialist politician who served as the 28th president of Chile from 1970 until his death in 1973. As a socialist committed to democracy, he has been described as the first Marxist to be elected president in a liberal democracy in Latin America.

He was the son of Arturo Alessandri, who was president from 1920 to 1925 and again from 1932 to 1938.
Salvador Allende was the president of Chile from 1970 until his suicide in 1973, and head of the Popular Unity government; he was a Socialist and Marxist elected to the national presidency of a liberal democracy in Latin America. In August 1973 the Chilean Senate declared the Allende administration to be "unlawful," Allende's presidency was ended by a military coup before the end of his term.

The military regime in Chile led by General Augusto Pinochet ended on 11 March 1990 and was replaced by a democratically elected government. The transition period lasted roughly two years, although some aspects of the process lasted significantly longer. Unlike most democratic transitions, led by either the elite or the people, Chile's democratic transition process is known as an intermediate transition – a transition involving both the regime and the civil society. Throughout the transition, though the regime increased repressive violence, it simultaneously supported liberalization – progressively strengthening democratic institutions and gradually weakening those of the military.
The Parliamentary Era in Chile began in 1891, at the end of the Civil War, and spanned until 1925 and the establishment of the 1925 Constitution. Also called "pseudo-parliamentary" period or "Parliamentary Republic", this period was thus named because it established a quasi-parliamentary system based on the interpretation of the 1833 Constitution following the defeat of President José Manuel Balmaceda during the Civil War. As opposed to a "true parliamentary" system, the executive was not subject to the legislative power but checks and balances of executive over the legislature were weakened. The President remained the head of state but its powers and control of the government were reduced. The Parliamentary Republic lasted until the 1925 Constitution drafted by President Arturo Alessandri and his minister José Maza. The new Constitution created a presidential system, which lasted, with several modifications, until the 1973 coup d'état.
The president of Chile, officially the president of the Republic of Chile, is the head of state and head of government of the Republic of Chile. The president is responsible for both government administration and state administration. Although its role and significance have changed over time, and its position and relations with other actors in the national political organization have also evolved, it remains one of the most prominent political offices in the country. It is also considered one of the key institutions that form the "Historic Constitution of Chile," and is crucial to the country's political stability.
The Presidential Republic is the period in the history of Chile spanning from the approval of the 1925 Constitution on 18 September 1925, under the government of Arturo Alessandri Palma, to the overthrow of the Popular Unity government headed by the President Salvador Allende on 11 September 1973. The period is concurrent with the "Inward Development" period in Chilean economic history.
The history of the Constitution of Chile dates from 1811. There were 10 constitutional texts and a draft for a federal organization in 1826. Its common elements are the unitary form of state and presidentialism as a form of government.
