Webster–Hayne debate on states' rights

Background. The debate arose from the "Foot resolution," introduced on December 29, 1829, by Senator Samuel A. Foot. It centered on the South Carolina nullification crisis of the late 1820s, where Calhoun and allies sought to nullify the Tariff of 1828, known as the "Tariff of Abominations." Hayne, a vocal proponent of states' rights and compact theory, opposed protectionist federal tariff bills, while Webster had previously backed tariff increases.

Participants. Robert Y. Hayne served in the U.S. Senate from 1823 to 1832 and chaired the Committee on Naval Affairs. He was an ardent free-trader and advocate for states' rights. Daniel Webster, a prominent lawyer and statesman, represented Massachusetts. He became a leading opponent of Andrew Jackson's policies after the 1828 election and was considered a top orator, with his 1830 speech regarded as the most eloquent ever delivered in Congress.

Significance. The heated speeches were unplanned and stemmed from the debate over the Foot resolution. Webster's Second Reply to Hayne is widely regarded as one of the greatest speeches in Congress. The debate is considered a defining episode in the constitutional crisis which precipitated the American Civil War, highlighting the tension between federal authority and states' rights doctrines.
