The Treaty That Ended the War

An information text written for this worksheet. The war ended with the Treaty of Guadalupe Hidalgo, signed on February 2, 1848. Mexico accepted the Rio Grande as the border of Texas. Mexico gave up about half of its land, including California and the lands that became Nevada and Utah and parts of Arizona, New Mexico, Colorado and Wyoming. The United States paid Mexico $15 million. Tens of thousands of Mexican citizens lived in the lands that changed hands. The treaty promised them US citizenship and protection of their property, but many later lost their land. Some Americans, such as Abraham Lincoln, had opposed the war. Others celebrated the new land.

  1. 1. Did the treaty's promises protect everyone's land? How can you tell?
  2. 2. Did all Americans agree about the war? How can you tell?
  3. 3. When was the Treaty of Guadalupe Hidalgo signed?
2.Look at the source, then answer the questions.

Lincoln's Spot Resolutions

From the "Spot Resolutions" that Representative Abraham Lincoln, a member of Congress, put forward on December 22, 1847. The word help line was added for this worksheet. First. Whether the particular spot of soil on which the blood of our citizens was so shed, was, or was not, within the territories of Spain, at least from the treaty of 1819 until the Mexican revolution. Word help: the "Mexican revolution" here means Mexico's fight for independence from Spain, which Mexico won in 1821.

  1. 1. What does Lincoln want to know about the spot of soil?
  2. 2. Lincoln was a member of Congress. Why might he put a question like this to the whole Congress?
  3. 3. What happened on that spot of soil, according to Lincoln?
