During which years did the War of the Triple Alliance occur?

The War of the Triple Alliance, also known as the Paraguayan War, took place from 1864 to 1870. This conflict involved Paraguay fighting against an alliance of Argentina, Brazil, and Uruguay. It was one of the bloodiest wars in Latin America's history and had significant implications for the region, leading to the devastation of Paraguay and altering the balance of power in South America.

The other time frames listed in the options pertain to different historical events or periods, which do not relate to the War of the Triple Alliance. For example, the years 1952-1960 do not correspond to this war, as they fall in the mid-20th century, long after the conflict had ended. The time frame 1346-1356 is associated with the Hundred Years' War and the Black Death in Europe. Similarly, the years 1570-1580 reference events related to the Spanish Empire and conflicts in Europe, also unrelated to the War of the Triple Alliance. Therefore, the first option encapsulates the accurate timeline for this specific historical war.
