The history of Uruguay comprises different periods: the pre-Columbian time or early history (up to the 16th century), the Colonial Period (1516–1811), the Period of Nation-Building (1811–1830), and the history of Uruguay as an independent country (1830–present).

Written history began with the arrival of Spanish chroniclers in the expedition of Juan Díaz de Solís in 1516 to the Río de la Plata, which marks the beginning of Spanish occupation of the region.

In 1527 the first European settlement was established in the territory of present-day Uruguay. It was called Sán Lázaro and founded by Sebastian Cabot who was in command of a Spanish expedition. In 1777 the Spanish Crown established the Viceroyalty of the Río de la Plata, which began to disintegrate with the Revolution of May 1810.

The territory of present-day Uruguay was invaded by the United Kingdom of Portugal, Brazil and the Algarve, initially becoming part of the Portuguese kingdom as Cisplatina Province. Between 1824 it was annexed to the Empire of Brazil, and a year later it declared its independence, which began the Cisplatine War. In 1828, with British mediation, a peace agreement was signed and the independence of Uruguay was recognized. In 1830 the country's first constitution was promulgated.
