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 democratic socialist committed to democracy, he has been described as the first Marxist to be elected president in a liberal democracy in Latin America.

The President of Chile, officially known as 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.
