- In the years before the Civil War, the U.S. expanded significantly. Manifest Destiny, or the idea that it was the God-given right of white settlers to settle the West, was the driving force behind expansion. This expansion came at the cost of Native Americans, who were forced off their land and, eventually, onto reservations.
- The U.S. obtained a large portion of the Southwest after defeating Mexico in the Mexican-American War, which lasted from 1846 - 1848. The U.S. provoked an attack by sending troops into disputed territory south of the Rio Grande, under the orders of President James Polk.
- The U.S. also experienced an increase in immigration during this time, leading to a wave of nativism. Many of the immigrants were from Ireland as they were escaping a deadly famine that took hold of their country.
