Chaco Armistice Day
June 12, Thursday

Historical Background
The Chaco War took place between 1932 and 1935 over control of the Gran Chaco region, a sparsely populated area believed at the time to be rich in oil. The war was one of the bloodiest in Latin American history during the 20th century, with both nations suffering heavy casualties.
On June 12, 1935, a ceasefire agreement was signed in Buenos Aires, Argentina, effectively ending the hostilities. The armistice marked the beginning of peace negotiations, which ultimately led to a formal peace treaty in 1938. Paraguay retained control over most of the disputed territory.
