““Jackson himself described how the treaties were obtained: “. . . we addressed ourselves feelingly to the predominant and governing passion of all Indian tribes, i.e., their avarice or fear.” He encouraged white squatters to move into Indian lands, then told the Indians the government could not remove the whites and so they had better cede the lands or be wiped out. He also, Rogin says, “practiced extensive bribery.” These treaties, these land grabs, laid the basis for the cotton kingdom, the slave plantations. Every time a treaty was signed, pushing the Creeks from one area to the next, promising them security there, whites would move into the new area and the Creeks would feel compelled to sign another treaty, giving up more land in return for security elsewhere. Jackson’s work had brought the white settlements to the border of Florida, owned by Spain. Here were the villages of the Seminole Indians, joined by some Red Stick refugees, and encouraged by British agents in their resistance to the Americans. Settlers moved into Indian lands. Indians attacked. Atrocities took place on both sides. When certain villages refused to surrender people accused of murdering whites, Jackson ordered the villages destroyed.””
