One argument that supported the Mexican-American War was the belief in Manifest Destiny, the idea that it was the United States' divine right and duty to expand its territory across North America. Proponents argued that acquiring land from Mexico would not only fulfill this destiny but also promote economic growth and spread democracy and civilization. Additionally, supporters claimed that the annexation of Texas and other territories would help secure the southern border and enhance national security.
