The Paraguayan War, also known as the War of the Triple Alliance and the Great War in Paraguayball, was a South American war fought from 1864 to 1870 between 
Paraguayball and the Triple Alliance of 
Argentinaball, the 
Brazilian Empireball, and 
Uruguayball. The war was the deadliest and bloodiest in Latin America's history. It particularly devastated Paraguayball, which suffered catastrophic losses and was forced to cede clay to Argentinaball and Brazilian Empireball. It made Paraguayball hate The Triple Alliance members for turning him into a shitty countryball and sexual slave.
Prelude
In 1863 Uruguay was in a civil war between the 
colorados and 
blancos political parties, but in 1864 Brazil entered the war to help the colorados, thing that made Paraguay angry due to being friend of the blancos goverment, because of this, Paraguay invaded the disputed territory of Matto Grosso between him and Brazil, starting the war.
After successfully invading taking 
Matto Grosso from Brazilball, Paraguay wanted to march into Uruguay to help his friend, BUT, he had to pass through Argentina to do that, and Argie said no, so Paraguay invaded 
Corrientes to go into Uruguay's clay in 1865.
The colorado party won, and Brazil, Argentina and Uruguay firmed the Triple Alliance pact to attack Paraguay together.
Start of the War
Argentina kicked Paraguay out of Corrientes, but it wasn't sure if attacking its brother was a good thing to do.
At the same time, Uruguay and Brazil kicked Paraguay out of Matto Grosso, because of these defeats Paraguay retreated to it's own clay
The War
In 1866 the allies attacked Paraguay in the battle of Tuyutí and he loosed the battle and his best troops.
Brazil and Argentina believed that Paraguay will be easy to defeat so they went to the Curupaytí battle without preparation against artillery, the result was Paraguay's artillery beating the hell out of both of them.
In 1867 the three allies entered Paraguay's part of the Parana River and the Second Battle of Tuyutí started, and the allies barely won.
After this, Paraguay tried to talk with Argentina to solve the conflict, but it didn't worked.
All this time Brazil was infected with cholera, and Argentina, along with Uruguay got infected too. Argie and Brazil got a very hard time with this, and the paraguayan civilians too.
In 1868 Brazil defeated Paraguay in the battles of Itororó and Abay, making Guay retreat.
Uruguay, Argentina and Brazil totally raped Paraguay in the Battle of Itá-Ibaté. Paraguay had to hide behind 
Asuncionball after that.
In 1869 Brazil and Uruguay took Asuncion and destroyed it. Argentina didn't wanted to be part of that.
Paraguay started becoming crazy, harming himself every time he failed a mission and made Piribebuýball the new capital.
The allies bombed Paraguay and the civilians got raped by Brazil again, and the Battle of Acosta Ñu started, Paraguay attacked with sticks and got massacred.
End of the war.
3 of Paraguay's capitals during the war falled and he decided to fight the final battle near a river with everything he had left.
Brazil arrived to the place of the battle and the final fight started, Paraguay, despite being wounded as hell and barely having things to fight with, he didn't surrendered and both ended up near the river, where Paraguay ignored Brazil's order to surrender again and shouted his famous line "¡MUERO CON MI PATRIA!" (I DIE WITH MY FATHERLAND!) and charged against Brazil, who made the final push and defeated Paraguay.
Post-War (1870-Present Day)
The poor boy still suffers from the PTSD and some other mental problems, he still pays reparations to 
Brazil and Argentina even though he didn't do much damage to them. Causing his economy to be shitty and his army poor.
Now Paraguayball sells pirated products like 
Chinaball to all other countries of the south america and plays soccer with them too even though he is pretty bad at it. Nothing changed much except Paraguayball is now bullied by Brazil, Argentina and Uruguay. Paraguay now suffers from economic problems, but he is a member from 
UNASUR and is pretty friendly with the others countries now, The other Belligerents only got stronger and kept on their path.
