Indians once ruled over all of North America, then Europeans came and weakened them with disease, stole their land and herded them to Oklahoma as the Europeans expanded westward under the theory of Manifest Destiny, a nationalism movement in the 1830’s. Throughout this time period, the Democratic Party ruled developing a set of ideas that formed the foundation of the modern party. Then again in the 1940s through 1960s the nationalism movement became popular again under ruling by the Democratic Party and Indians were again run off their sovereign land, disbursed across America and left seemingly with nothing.
