Originally, Uruguay was home to small groups of indigenous tribes. During European colonization, nearly all the indigenous population was conquered, killed, or driven out. In what year did the Spanish explorers first land in the area?

Spanish explorers first reached the area that is now Uruguay in 1516, when Juan Díaz de Solís explored the Río de la Plata region. Therefore, the correct choice is 1516. The year 1492 marks Columbus’s first voyage to the Americas, not the Spanish arrival in Uruguay.
