Paraguay had been involved in territory, boundary, and tariff disputes for years with their neighbors Argentina and Brazil. When Brazil aided Uruguay in an oust of Paraguay, the Paraguayan leader Francisco Solano López, declared war on Brazil. Though Argentina was not directly involved with this conflict, they took it upon themselves to make an alliance with Brazil and Uraguay. This alliance is known as the Triple Alliance.

The war ended with The Triple Alliance overthrowing Paraguay. Though Lopez had successfully invaded Brazil, his attempt at Paraguay was a disaster. He was forced to withdraw and was eventually killed.
