The military coup to unseat President Juan Perón of Argentina is launched at midnight.

Juan Domingo Perón was an Argentine military officer and statesman who served as the 29th president of Argentina from 1946 to his overthrow in 1955 and again as the 40th president from 1973 to his death in 1974. He is the only Argentine president elected three times and holds the highest percentage of votes in clean elections with universal suffrage. Perón is arguably the most important and controversial Argentine politician of the 20th century and his influence extends to the present day. Perón's ideas, policies and movement are known as Peronism, which continues to be one of the major forces in Argentine politics.
