The Texas annexation, the Mexican Cession, and the Gadsden Purchase all contributed to the present-day borders of the lower 48 U.S. territories. The Texas annexation in 1845 added Texas to the United States, while the Mexican Cession in 1848, which followed the Mexican-American War, included California and much of the Southwest. The Gadsden Purchase in 1853 further defined the southern boundary of the U.S. by acquiring land in present-day Arizona and New Mexico. Together, these events shaped the continental boundaries of the United States.
