Map of Texas and the Countries Adjacent: Emory, W. H.
Compiled in the Bureau of the Corps of Topographical Engineers From the Best Authorities, For the State Department, 1844
This map accompanied the annexation treaty negotiated between the U.S. and Texas in 1844, and was part of the accompanying documentation sent to the Senate when the treaty was considered. For Texas to be annexed to the U.S. by treaty, the Senate had to ratify the treaty by 2/3 votes. It did not, and the treaty was defeated. As a result, the Texas annexation question became a political issue in the 1844 presidential election. It fell to lawmakers in Congress to find a solution.
