What was the purpose for the United States to acquire California and New Mexico from Mexico?

The 1848 Treaty of Guadalupe Hidalgo, forced onto the remnant Mexican government, ended the war and enforced the Mexican Cession of the northern territories of Alta California and Santa Fe de Nuevo México to the United States. In 1849, Californians sought statehood and, after heated debate in the U.S. Congress arising out of the slavery issue, California entered the Union as a free, nonslavery state by the Compromise of 1850. California became the 31st state on September 9, 1850. California was under U.S. control by January 1847 and formally annexed and paid for by the U.S. in the Treaty of Guadalupe Hidalgo signed in 1848. With millions of acres of farmland, California leads the U.S. in agricultural production. The state is also home to famous cultural institutions and national parks including: Hollywood, and Disneyland,
