The United States Congress approved the annexation of Texas through a joint resolution, a maneuver necessitated by the Senate's rejection of a treaty. This legislative action, driven by President Tyler's lobbying and Southern Whig amendments, culminated in a Senate vote on February 27, 1845, and subsequent presidential signing on March 1, 1845.

Background and detail

Background. President Tyler pursued Texas annexation independently to secure political support, initiating secret negotiations in 1843. However, the Senate rejected the resulting treaty in June 1844, prompting Tyler to seek annexation via joint resolution. This approach bypassed the two-thirds treaty requirement, relying on simple majority passage protocols established during the lame-duck session of the 29th Congress.

Legislative Debate. Southern Whigs introduced amendments in January 1845 to enhance slaveowner gains, while Senator Benton proposed an alternative resolution focusing on border disputes. President-elect Polk desired annexation before his inauguration. The Senate voted 27–25 to admit Texas on February 27, 1845, based on Tyler's protocols, despite earlier opposition from both major party leaderships.

Execution. The joint resolution passed Congress on February 26, 1845, according to one source, though the Senate vote occurred on February 27. President Tyler signed the bill on March 1, 1845, enacting Joint Resolution 8. On his last day in office, March 3, Tyler dispatched the offer to Texas under the Brown-Foster option terms.
