The two main causes of the United States' war with Mexico were disputes over territorial boundaries and the U.S. desire for westward expansion. The annexation of Texas in 1845, which Mexico still considered part of its territory, heightened tensions. Additionally, the U.S. aimed to acquire California and other Mexican territories, driven by the belief in Manifest Destiny. These factors ultimately led to the outbreak of the war in 1846.
