[133] After Jacksonians took power in 1827, they devised a tariff bill designed to appeal to Western states while instituting high rates on imported materials important to the economy of New England. It is unclear whether Van Buren, who shepherded the bill through Congress, meant for the bill to pass, or if he had deliberately designed it to force Adams and his allies to oppose it.[134] Regardless, Adams signed the Tariff of 1828, which became known as the "Tariff of Abominations" by opponents. Adams was denounced in the South, and he received little credit for the tariff in the North.[135]

Adams sought the gradual assimilation of Native Americans via consensual agreements, a priority shared by few whites in the 1820s. Yet Adams was also deeply committed to the westward expansion of the United States. Settlers on the frontier, constantly seeking to move westward, cried for a more expansionist policy that disregarded the concerns of Native Americans. Early in his term, Adams suspended the Treaty of Indian Springs after learning that the Governor of Georgia, George Troup, had forced the treaty on the Muscogee.
