The War of the Triple Alliance

The War of the Triple Alliance (1864-1870) was a conflict in South America involving Paraguay against Brazil, Argentina, and Uruguay. Paraguay, led by Francisco Solano López, sought to assert regional influence and defend its interests, prompting its neighbors to form an alliance to counteract its expansion. The war was brutal and destructive, resulting in heavy Paraguayan losses and significant regional instability. It was one of the deadliest conflicts in the 19th century in the Americas, reshaping political borders and impacting the development of the involved countries.
