The correct option is: "Native Americans were segregated to reservation "
When the Spaniards discovered the American continent - which ended up being called "America" from the year 1507, in honor of the Italian geographer and navigator, Americo Vespuccio, who concluded that it was a new continent - and also when the pilgrims arrived at the Atlantic coasts of the northeast of the territory that would eventually become the United States, they realized that it was populated by native inhabitants, who were called "Indians" because, originally, the trip of Christopher Columbus was intended to find a new maritime route to India.
The Indigenous Reserves are part of the US territory. Because their inhabitants are natives (Amerindians), they have been allowed to conserve part of their lands, with limited self-government. They are a kind of Domestic Nations. The Nations are characterized by having only territory and population, while the States have territory, population and autonomous government.
