Following the passage by the United States Congress of a proposed Resolution Annexing Texas to the United States, Anson Jones assembled the Convention of 1845 to consider the proposal. Sessions opened on the Fourth of July, and members elected Thomas Jefferson Rusk to lead the convention.

With very little discord, the convention voted fifty-five to one to approve the offer of annexation. Richard Bache of Galveston and a grandson of Benjamin Franklin was the lone dissenter.

Several committees were appointed to guide the executive, legislative, judicial and other provisions for a new state constitution, and the convention then set about adopting the Constitution of 1845.

With its mission finished, the convention adjourned on August 28th 1845.
