Guaraní War: The leader of the Guaraní rebels, Sepé Tiaraju, is killed in a skirmish with Spanish and Portuguese troops.

The Guaraní War of 1756, also called the War of the Seven Reductions, took place between the Guaraní tribes of seven Jesuit Missions and joint Spanish-Portuguese forces. It was a result of the 1750 Treaty of Madrid, which set a line of demarcation between Spanish and Portuguese colonial territory in South America.

The Guarani are a group of culturally-related Indigenous peoples of South America. They are distinguished from the related Tupi by their use of the Guarani language. The traditional range of the Guarani people is in what is now Paraguay between the Paraná River and lower Paraguay River, the Misiones Province of Argentina, southern Brazil once as far east as Rio de Janeiro, and parts of Uruguay and Bolivia.

Sepé Tiaraju was a Guaraní leader in the Jesuit reduction mission of São Luiz Gonzaga.
