In November 1889, after a long attrition with the monarchical regime deepened by the abolition of slavery, the army led a coup d'état that resulted in the end of the empire and the founding of a republic. The implementation of the first Brazilian military dictatorship (that ended in 1894), was followed by a severe economic crisis that deepened into an institutional one with Congress and the Navy, which degenerated into a restricted civil war in the southern region.
