Mexican-American War and Its Consequences

In 1844, President James K. Polk aimed to expand the U.S. from coast to coast, driven by manifest destiny. In 1845, he attempted to purchase California from Mexico, but tensions over Texas led to conflict. Polk sent troops to the disputed Rio Grande border, prompting war with Mexico in 1846. Key battles included victories by Generals Zachary Taylor and Winfield Scott. The 1848 Treaty of Guadalupe Hidalgo ended the war, granting the U.S. vast territories. This expansion intensified debates over slavery, contributing to the Civil War.
