This chapter covers the territorial growth of the United States. Supported by the ideology of “manifest destiny,” Americans added Oregon, Texas, California, and the Southwest to the nation’s territory. Through diplomacy and war, the United States became a continental nation. Settlers repeated the old pattern of initial friendliness to natives and earlier settlers, followed by hostility and domination. Adding new territory also caused intensification of sectional hostility over extending slavery into new territory.
