before her first husband John Timberlake died, and they married nine months after his death. With the exception of Barry's wife Catherine, the cabinet members' wives followed the lead of Vice-president Calhoun's wife Floride and refused to socialize with the Eatons. Though Jackson defended Margaret, her presence split the cabinet, which had been so ineffective that he rarely called it into session, and the ongoing disagreement led to its dissolution. In the spring of 1831, Jackson demanded the resignations of all the cabinet members except Barry, who would resign in 1835 when a Congressional investigation revealed his mismanagement of the Post Office. Jackson tried to compensate Van Buren by appointing him the Minister to Great Britain, but Calhoun blocked the nomination with a tie-breaking vote against it. Van Buren—along with Amos Kendall, who helped organize what would become the Democratic Party, and Francis Preston Blair, the editor of The Globe newspaper that served as Jackson's house organ,—would become regular participants in Jackson's Kitchen Cabinet, an unofficial, varying group of advisors that Jackson turned to for decision making even after he had formed a new official cabinet.

Before Jackson took office, the relationship between the southern states and the Native American tribes who lived within their boundaries was strained. The states felt that they had full jurisdiction over their territories; the native tribes saw themselves as autonomous nations that had a right to the land they lived on. Significant portions of the five major tribes in the Southwest—the Cherokee, Choctaw, Chickasaw, Creek, and Seminoles— began to adopt white culture, including education, agricultural techniques, a road system, and rudimentary manufacturing. In the case of the tensions between the state of Georgia and the Cherokee, Adams had tried to address the issue encouraging Cherokee emigration west of the Mississippi through financial incentives, but most refused. In the first days of Jackson's presidency, some of the southern states had passed legislation extending state jurisdiction to Native American lands. Jackson supported the states' right to do so. His position was later made clear in the 1832 Supreme Court test case of this legislation, Worcester v. Georgia. Georgia had arrested a group of missionaries for entering Cherokee territory without a permit; the Cherokee declared these arrests illegal. The court under Chief Justice John Marshall decided in favor of the Cherokee:
