Prehistory and the First Peoples

Mounds, plains and the first peoples

For millennia the land between the Uruguay River and the Atlantic had no states, only bands and confederations of peoples who moved with the seasons. The oldest human traces are roughly 10,000 years old, left by hunter-gatherers who followed game across the grasslands. Later groups, including the Charrua, Chana, Guenoa and Minuan, organised themselves around kin and the leadership of respected chiefs. Guarani communities settled along the river and the north. None built a centralised polity, and the Spanish and Portuguese later treated the territory as largely empty.

Daily life rested on hunting, fishing and gathering, with mobility the key to survival. Archaeology records stone points, the early bolas weapon, rock art and the earthen mounds of the eastern wetlands, which show that some communities invested in lasting landscape works and used the lagoons seasonally. Estimates cited for the early sixteenth century put the Charrua at roughly 9,000 people, with a further 6,000 Chana and Guarani. Their way of life depended on open country, rivers and wide networks of exchange and alliance.

The legacy of these peoples is contested and still being rewritten. After Spanish contact the horse and cattle transformed Charrua life and made them formidable opponents of colonial settlement for three centuries. The Salsipuedes campaign of 1831 and the capture of four survivors, who were exhibited in Paris, led many to speak of a national myth of disappearance. Modern research on genetics, descendants and identity challenges that story, and Uruguay today recognises indigenous heritage more openly.
