The 1917 Costa Rican coup d'état of 27 January 1917 was a rupture of the constitutional order in the Republic of Costa Rica, where the constitutional President Alfredo González Flores,[1] was overthrown by his Minister of War and Navy Federico "Pelico" Tinoco and his brother and army commander José Joaquín Tinoco.
[2] Tinoco, in addition to the support of the most conservative oligarchy, had the support of the Catholic Church, of the Army (commanded by his brother), of important political and intellectual figures and of wide sectors of the population, although the repressive brutality of the regime was slowly undermining his popularity.
The US government under President Woodrow Wilson did not recognize Tinoco as part of its policy of rejecting coups in Central America in order to promote stability.
His brother José Joaquín was assassinated on August 10, 1919 and rebel forces had already entered the country with varying degrees of success.
The following elections of 1919 were won by the leader of the anti-Tinoco opposition Julio Acosta García on a landslide victory.
