The Chilean presidential election of 1829 took place on May 15-16 1829, through a system of electors.
The newly enacted Constitution of 1828, provided that the President was to be chosen by electors. Two-hundred and sixteen electors, three for each congressman, were to be chosen. Each elector voted for two names, without specifying which vote was for President or Vice President.
The election was subject to abuses, so electors gave their vote to Francisco Antonio Pinto and to Joaquín Vicuña.
Even though Pinto was accepted as President, his resignation and replacement by Vice President Joaquín Vicuña, triggered the Chilean Civil War of 1829.
