The Annexation of Texas

Proponents•Americans who believed in Manifest Destiny wanted to admit Texas to the Union.•Supporters viewed the Texas Revolution in the spirit of the American Revolution.•Southerners supported annexation because Texas allowed slavery, and its admission would boost the South’s political power.

Opponents •Americans were concerned that the U.S. would have to bear the substantial Texas debt.•Northerners opposed annexation because it would spread slavery westward and increase slave states’ voting power in Congress. •A major argument in Congress was that the Constitution said nothing about admitting an independent nation.

The Alamo

• Santa Anna, head of Mexican government, defeated the Americans at the Alamo and killed all the defenders

The Annexation of Texas

•A Republic for nine years– The annexation question was a significant issue in the 1844

presidential election. When James K. Polk, the pro-annexation candidate, won, Mexico warned that it would consider the annexation of Texas as a declaration of war.

•Texas becomes a state– Voters in Texas overwhelmingly approved annexation, and Texas

became a part of the United States on December 29, 1845.
