What happened for Mexico in 1846-1848?

The United States and Mexico went to war over the annexation of Texas in 1846. The war lasted two years and resulted in a decisive victory for the United States. As a result of the war, Mexico ceded to the United States the present-day states of California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado and Wyoming.

Causes of the War

There were a number of causes of the Mexican-American War, including:

* The annexation of Texas. Mexico had never recognized the independence of Texas, and it considered the US annexation of Texas in 1845 to be an act of war.

* The border dispute. There was a dispute over the boundary between the United States and Mexico. The United States claimed that the border was the Rio Grande, while Mexico claimed that it was the Nueces River.

* Manifest Destiny. Many Americans believed that the United States was destined to expand its territory across the North American continent. This belief helped to fuel support for the war.

Course of the War

The Mexican-American War began in 1846 and lasted until 1848. The war was fought on two fronts: in the west, American forces invaded California and New Mexico, while in the east, they invaded Mexico itself.

Western Front

In the west, American forces under the command of General Stephen Kearny invaded California in 1846. They quickly defeated the Mexican forces in California and established control of the region. American forces also invaded New Mexico and defeated the Mexican forces there.

Eastern Front

In the east, American forces under the command of General Zachary Taylor invaded Mexico in 1846. They won a series of battles against the Mexican forces and advanced into Mexico. In 1847, American forces under the command of General Winfield Scott landed at Veracruz and marched inland to Mexico City. They captured Mexico City in September 1847.

Treaty of Guadalupe Hidalgo

The Mexican-American War ended with the signing of the Treaty of Guadalupe Hidalgo in 1848. Under the terms of the treaty, Mexico ceded to the United States the present-day states of California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado and Wyoming. The United States also paid Mexico $15 million.

Impact of the War

The Mexican-American War had a profound impact on both the United States and Mexico. For the United States, the war resulted in the acquisition of a vast amount of territory and the emergence of the United States as a major world power. For Mexico, the war resulted in the loss of half of its territory and the decline of its status as a regional power.
