A continent already inhabited before 1500
When the Portuguese caravels arrived, the territory that became Brazil had already been occupied for thousands of years by millions of people, split into hundreds of peoples with very different languages, gods and social organization. Tupis on the coast, Jês in the interior, Amazonian groups with their own agriculture: there was no single Indigenous people, there was an enormous diversity that the newcomers decided to call all one thing, "Indians," out of convenience.
These societies were not an empty space waiting for civilization to show up. They had trade between villages, war, religion and hierarchies of their own. Seeing 1500 as a blank page turning into civilization is an old mistake: in reality, two worlds that didn't know each other met, and one of them arrived armed and carrying new diseases.
Many people don't realize it, but a good share of the names of cities, rivers and even everyday foods in Brazil come straight from these Indigenous languages, not from Portuguese. It's a trail that survived, even after so much violence against the people who spoke those languages first.
