The passage of a new tariff law, on July 14, which was considered harmful to Southern interests, brought the Federal Government into armed conflict with the South. On November 19, a State Convention met at Columbus, South Carolina, in response to a call of the Legislature, and on the 24th a nullification ordinance was adopted. The tariff laws were declared unconstitutional, and therefore "null and void and no law, nor binding upon the State." On December 10, President Jackson issued a proclamation against nullifiers, threatening them with trial for treason. Governor Hamilton of South Carolina in reply warned citizens not to be diverted from their allegiance to their State by this Federal proclamation. Jackson summoned General Scott to Washington and sent a part of the army to Charleston with a ship of war to collect the revenues. On December 28, J.C. Calhoun resigned the office of Vice-President on account of Jackson's proclamation. He was forthwith elected Senator from South Carolina. [Sidenote: Treaty of Payne's Landing] [Sidenote: Troubles with Indians] [Sidenote: Black Hawk War] It was during this year that renewed troubles with the Seminoles in Florida resulted in one of the most serious Indian wars of the century. By the treaty of Fort Muller, in 1823, the Indians were to be confined to a reservation on the eastern peninsula, but the Territorial Legislature petitioned Congress for their removal. Finally, in 1832, the treaty of Payne's Landing stipulated that seven Seminole chiefs should examine the country assigned to the Creeks west of the Mississippi, and that if they could live amiably with the Creeks, the Seminoles were to be removed within three years, surrendering their lands in Florida, and receiving an annuity of $15,000 and certain supplies. President Jackson sent a commission to the West to convince the seven chiefs that the country was eminently desirable, and a supplementary treaty from these seven was obtained without consulting the rest of the Seminoles. Many Seminoles were opposed to moving West through fear of the Creeks. The Sacs and Foxes and Winnebago Indians of Wisconsin by treaty, in 1830, had ceded their lands to the United States, but they still refused to leave their territory. Governor Reynolds, of Illinois, called out troops to compel them to go to the lands set apart for them, west of the Mississippi. Black Hawk returned, but was again driven off. In 1832 he came back with a thousand warriors and Indian warfare broke out. Generals Scott and Atkinson were sent with troops to Rock Island. It was the first time that a steamboat was used as a military transport. The force was there divided. General Scott could effect nothing, but General Atkinson pushed on, and in August defeated the Indians and took Black Hawk and his two sons prisoners.
