The Mexican-American War, which took place between 1846 and 1848, is an important chapter in U.S. history. It marked a pivotal moment in the expansion of the United States across North America. This war was sparked by the U.S. annexation of Texas, which had been an independent republic following its independence from Mexico.
The conflict arose mainly due to territorial disputes. The U.S. believed in the concept of "Manifest Destiny," which was the idea that it was America's fate to expand its territory across the continent. Thus, when the U.S. annexed Texas in 1845, it ignited tensions with Mexico, who still considered Texas part of its territory. As a result, the ensuing war led to significant territorial gains for the United States.
Key points to understand about the Mexican-American War include:
- It resulted in the United States gaining control over large territories, shaping the modern U.S. map.
- The Treaty of Guadalupe Hidalgo ended the conflict, with Mexico ceding nearly half of its territory to the U.S.
- This war set the stage for future conflicts and debates over the expansion of slavery in the new territories.
Understanding this historical context is crucial for grasping how the U.S. evolved territorially and politically during the 19th century.
