Overview
This chapter covers the 1800s, a century when the United States grew larger and fought a war that divided the country. You will learn about the Louisiana Purchase, the wars of the 1800s, the Civil War and Abraham Lincoln, and how voting rights and citizenship changed.
In 1803 the United States bought the Louisiana Territory from France. Wars fought by the United States in the 1800s include the War of 1812, the Mexican-American War, the Civil War, and the Spanish-American War.
The Civil War was the war between the North and the South, and it ended slavery. Important events include Fort Sumter, the Emancipation Proclamation, and the battle of Gettysburg. Abraham Lincoln, the 16th president, led the country during the war, saved the Union, and freed the slaves with the Emancipation Proclamation, which freed slaves in the Confederate states.
After the war, the 14th Amendment said that people born or naturalized in the United States are citizens. All men got the right to vote after the Civil War with the 15th Amendment in 1870. Women such as Susan B. Anthony, Elizabeth Cady Stanton, and Sojourner Truth led the women's rights movement in the 1800s.
