Texas Becomes a State

  • Many Texans wanted Texas to join the Union. Southerners wanted Texas to become a state, but the Northers didn't want another slave.
  • The Manifest Destiny was a very popular idea in 1844, and the South wanted Texas, and the North wanted gain of Oregon territory. Candidate James K. Polk supported both, so after he won, Congress passed a resolution to annex Texas, and in 1845, Texas joined the Union.

  • Polk sent John Slidell, a representative for Polk, to Mexico to propose a deal. Slidell could offer $30 million for California and New Mexico as long as Mexico accepted the Rio Grande as the Texas border.

A War Plan

  • Polk planned to defeat Mexico by accomplishing three goals. First, the United States would drive Mexicans forces out of Texas. Then, it would seize New Mexico and California. Finally, American forces would advance into Mexico and capture the capital, Mexico City.
  • In 1847, Zachary Taylor completed goal #1. All of the important towns between Mexico and Texas were captured. General Stephen Kearney made progression toward goal #2 by marching his troops to the Santa Fe in 1846, after the Mexican governor fled.

California's Uprising

  • Before war with Mexico, American settlers in northern California had begun an uprising. They were encouraged by American general John C. Fremont.
  • With almost effortless overcoming of Mexican presence in the Mexican territory, on July 14, 1864, the Americans declared independence for California, as called themselves the Bear Flag Republic.

Peace Terms

  • With the defeat of Mexico on February 2, 1848, Mexico's leaders signed the Treaty of Hidaglo. Mexico gave the United States more that 500,000 square miles-which are today California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado and Wyoming-in trade for $15 million.
  • With Oregon and ex-Mexican territories under the American flag, the Manifest Destiny dream has been realized whether slavery should be allowed.
