The settlers were not moving into unpopulated territory, and conflict erupted with the native inhabitants. A major problem was the different concepts of legality held by the respective sides: while whites believed they had bought a given area quite fairly, Indians often argued that the sellers had no right to trade in tribal property, and even that land as such could not be sold. Throughout the 1820’s pressure for their removal mounted and the inauguration of president Andrew Jackson in 1829 provided the ideal opportunity for the advocates of white settlement – still worse for the Indians, in 1829 gold was discovered on Indian lands in Georgia. The tribes were pressed to accept relocation in a new ‘Indian territory’ west of the Mississippi and at least some of the elements of the leadership did consent. In 1830 Jackson signed the Indian Removal Act. These actions were probably illegal as well as high-handed, and Jackson ignored the condemnation of the US supreme court.
