Mexican and American War
Treaty of Guadalupe Hidalgo
Territories acquired by the U.S. under the Treaty of Guadalupe Hidalgo are present day Nevada, Arizona, Wyoming, California, Colorado, Utah, and New Mexico, also Mexico gave up all claims to Texas and recognized the Rio Grande River as America's southern boundary.
A great increase of immigrants from Europe, was due to the large economic opportunities in the U.S. Immigrants from China moved to California as the effect of the gold rush, to assist with the mines and railway systems, as well as people from Italy and Asia migrated to Latin America to work in the agriculture such as sugar fields. Other fields that were major in the industries were iron, textiles, and steel.
Railway System in the U.S.
Railroads have spanned the continent and united the country in an unprecedented transportation network. Personal mobility radically expanded; one could travel across the country in a week in the 1870s instead of taking several months just a decade before.
Military Advantages for the United States
Soldiers in the US Army enlisted for a five year period and were overseen by officers commissioned by Congress. Although there were approximately 8,613 soldiers, only 5,500 men actively served in the US-Mexico War. Several of the officers were recent graduates of the United States Military Academy, including Ulysses S. Grant and Robert E. Lee. However, there was little interaction between officers and common soldiers, which resulted from the strict military hierarchy. On February 11, 1847 Congress created an additional ten regiments to the national Army to serve for the duration of the war.
Key victories for U.S. Forces
August 1846 Kearny, of the American forces, take control of Sante Feel, a major Mexican Trading Post, which led to Mexico attacking Kearny's forces again but Kearny still with the victory over Mexico, but barely surviving the attack. The California forces then retreat as American forces then cross the San Gabriel River and take Los Angeles as well. March 1847 Winfield Scott with his 14,000 men capture Port Veracruz then take over Mexico City, as Santa Anna loses 4,000 men. Ends with the Treaty of Guadalupe Hidalgo.
U.S. Policy Regarding Native Americans
Assimilation was a constant policy of the U.S. The increase of the idea of Menifest Destiny increased the pressure on the Native Americans warfare, and rising tension. In the 1830's Congress passed the Indian Removal Act, giving the government power to relocate Native Americans from their homeland to new established states of land west of the Mississippi River.
