we genocided our natives after using them in the wars against spain, brazil, etc. to secure our independence. once our country was established we began to produce meat and whool to export and there was really not a place anymore for the dumb Charrua indians whom would kill a whole random cow owned by someone just to eat a steak. so we genocided them in the "Massacre of Salsipuedes", we pretty much drove them to the shore of a river and slaughtered every man woman and child of the Charrua people. in the long term it was for the best. we are 90% white and have a somewhat traditional and functioning country.
