In 1863 and 1864, historical and political contradictions in the River Plate region led to civil war in Uruguay, creating tensions with neighboring nations in the region. The Brazilian government intervened both politically and militarily in Uruguay to address the interests of ranchers in its province of Rio Grande do Sul, to distract the attention of the Brazilian citizens from domestic problems, and to preserve the political influence of the Empire of Brazil on Uruguay. This action by the Empire clashed with the new Paraguayan policy of political interference in the River Plate region and resulted in the declaration of war against Brazil by Paraguayan dictator Francisco Solano López. This conflict broadened into the Paraguayan War.

While Europeans basked in the glory of their so-called century of peace between the end of the Napoleonic wars (1815) and the onset of World War I (1914), Latin Americans knew no such luxury. Conflict became a way of life for Latin Americans attempting to construct nation-states. Liberals and Conservatives dueled with one another for political power, while caudillos (military strongmen) added their unique twisted logic to the political process. Historians have spilled considerable ink detailing these internal conflicts that complicated Latin America’s struggle for effective state formation in the early national period but have paid much less attention to the external wars over disputed boundaries that involved every South American nation during the 19th century. As historian Robert Burr described it: boundary conflicts were the “congenital international disease of Spain’s former colonies.”

In the period 1870–1936, Paraguay began to redevelop economically after its devastating loss in the War of the Triple Alliance (1864–1870). Turning to a liberal economic model popular in the region at the time, government officials began selling off large tracts of land to foreign investors, in particular Argentine investors. The liberal era in Paraguay was notoriously turbulent as political rivals often relied on Civil War to gain power. Nonetheless, this period was pivotal in helping to shape ideas about the nation. The era ends at the Febrerista Revolution (1936) when returning Chaco War (1932–1935) veterans made their mark on Paraguayan politics and identity.
