After years of refraining from annexing Texas after it won independence from Mexico in 1836, the U.S. admitted Texas into the union on December 29, 1845. The U.S. recognized the border of Texas to be at the Rio Grande, whereas Mexico claimed the boundary was the Nueces River. This dispute led to the Mexican-American War (1846-1848).

On February 2, 1848, the Treaty of Guadalupe Hidalgo was signed ending the Mexican-American War, After almost two years of war, the treaty added an additional 525,000 square miles to U.S. territory from present-day Texas to Nevada and up through Wyoming.

The Brazoria County Historical Museum once again welcomes Dr. Paul Pedisich on Thursday, August 8th at 6:30pm, to explore the role of the Guadalupe Hidalgo Treaty in the history of Texas and the United States.

Admission is free to the public. The Museum is located at 100 East Cedar in Angleton. For more information, follow the Museum on Facebook or call 979-864-1208.
