The War of the Triple Alliance or War of Paraguay, called by the Paraguayans Guerra Grande, War against the Triple Alliance, was the military conflict in which the Triple Alliance - a coalition formed by the Empire of Brazil, Uruguay, and Argentina - fought militarily against Paraguay between 1864 and 1870 .

The war ended in 1870 with a defeat in Paraguay, which also led to a demographic disaster: according to different sources, the country lost between 50% and 85% of its population and perhaps more than 90% of its adult male population
