The President is responsible for both government and state administration. Although its role and significance has changed over the history of Chile, as well as its position and relations with other actors in the national political organization, it is one of the most prominent political figures.

In developing the current Constitution of France (1958), former French president Charles de Gaulle said the head of state should embody "the spirit of the nation" (""). In some countries, typically those with parliamentary governments, the head of state is a ceremonial figurehead that does not actually guide day-to-day government activities and may not even be empowered to exercise any kind of political authority (e.g., Queen Elizabeth II in the United Kingdom). In other countries, the head of state is also the head of government, such as in the U.S., where the president is both a public figurehead and the actual highest ranking political leader who, in practice, oversees the executive branch. - Chile, officially the Republic of Chile, is a South American country occupying a long, narrow strip of land between the Andes to the east and the Pacific Ocean to the west.

Presidential candidates under its banner won every election from when military rule ended in 1990 until the conservative candidate Sebastian Pinera won the Chilean presidential election in 2010. - The territory of Chile has been populated since at least 3,000 B.C. By the 16th century, Spanish conquistadors began to subdue and colonize the region of present-day Chile, and the territory became a colony between 1540 and 1820, 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 neighbouring 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. - Argentina, officially the Argentine Republic, is a federal republic in the southern half of South America.

The provinces and the capital have their own constitutions, but exist under a federal system. - Easter Island is a Chilean island in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian Triangle.
