Main Causes of the Mexican and American War

The Mexican-American War, which took place between 1846 and 1848, was primarily caused by border disputes between Mexico and the United States, the annexation of Texas by the US, and the American desire to expand its territory to the Pacific Ocean.

The Mexican and American War was a significant conflict in the early to mid-19th century that shaped the territorial boundaries of the United States. One of the main causes of the war was the border disputes between Mexico and the US, specifically regarding the southern border of Texas. After gaining independence from Spain in 1821, Mexico considered Texas as part of its territory, while American settlers who had moved to the region sought to establish an independent republic. Tensions escalated, leading to the annexation of Texas by the US in 1845.

Another cause of the Mexican-American War was the US desire to expand its territory to the Pacific Ocean. The concept of Manifest Destiny, which was prevalent in American political ideology at the time, emphasized the belief that the United States was destined to expand across North America. This idea fueled the American ambition to acquire more land, including territories that belonged to Mexico.

Overall, the combination of border disputes, the annexation of Texas, and the American desire for territorial expansion created a volatile situation that eventually led to the outbreak of the Mexican and American War. The conflict had far-reaching consequences for both countries and played a crucial role in shaping the history of the United States.
