Section 5: The 1800s

The 19th century largely focused on two themes: the growth of the nation’s size and the ability of Americans to participate in its freedom. The nation continued to expand westward, particularly due to territorial gains in the Louisiana Purchase and after the Mexican-American War.

This territorial expansion heightened the stakes of slavery in a polarized nation. Most of the leading Founders had reviled slavery (even while tolerating it as a temporary necessary evil) and they expected it to die out. Instead, slavery thrived, not only growing economically but generating defenders, mostly in the South, who considered slavery a positive good to be defended and encouraged. Conversely, pressure to stop slavery’s expansion and even to abolish it entirely grew more intense in the North.
This tension over slavery eventually led to the Civil War, in which the country, under the leadership of Abraham Lincoln, eventually ended slavery via the Thirteenth Amendment. The efforts to secure the civil rights of black Americans, including former slaves, also developed into the effort to secure women’s rights as well, though women’s suffrage would not be universally achieved until 1920.

Section 5.1: Purchasing the Louisiana Territory

As the French government under Napoleon Bonaparte warred with its European neighbors and fought slave rebellions in the early 1800s, the country became both financially troubled and unable to commit soldiers to defend its North American territory. As a result, Napoleon instructed his government to sell the bulk of these massive holdings to the young American government. This offer resulted in the purchase of the Louisiana Territory, which covered more than current day Louisiana – it was a vast expanse between the Mississippi River and the Rocky Mountains.

Section 5.2: Wars of the 19th Century

America engaged in a variety of wars in the 19th century. The most important of these were the War of 1812, the Mexican-American War, and the Civil War. British efforts to effectively draft former British subjects, now American citizens, into serving in the British Navy against Napoleon eventually led to conflict with Britain in the War of 1812. Conflict-related to the acquisition of the former Mexican province of Texas led to the Mexican-American War in 1846. Perhaps most importantly, the United States of America engaged in a Civil War when southern states sought to secede to protect the institution of slavery. Finally, the brief Spanish American War in 1898 put an end to Spanish colonial presence in the Western Hemisphere.

Over the course of the 19th century, slavery polarized American politics. Where once most political leaders from across the country had looked forward to the day slavery would die out, in the early 1800s Southerners such as John Calhoun began defending it not as a necessary evil but a positive good, even for the slaves themselves. In the North, the abolitionist movement gained traction and grew increasingly intense in its rhetoric, as members of the movement argued for the immediate and complete elimination of slavery in the United States. Many other Americans, especially in the North, sought to arrest slavery’s growth in order to bring about its eventual collapse, and thus the newly formed Republican Party sought to end slavery in federal territory (that is, land that had not yet become a state).

Southerners, long used to using the power of the federal government to protect slavery over the protest of anti-slavery Northern states, feared the loss of this power. Thus, they responded to the victory of Abraham Lincoln and the anti-slavery Republican Party by seceding from the Union. This triggered the Civil War.

Section 5.3: The Thirteenth Amendment

Abraham Lincoln led the United States during the Civil War and is credited with saving or preserving the Union. In addition, Lincoln freed the slaves in Confederate states with the Emancipation Proclamation while also helping convince Congress to pass the Thirteenth Amendment, which decisively abolished slavery in the entire country.

“…this nation, under God, shall have a new birth of freedom -- and that government of the people, by the people, for the people, shall not perish from the earth.”

- Abraham Lincoln, Gettysburg Address, 1863

Section 5.4: Women’s Suffrage

Susan B. Anthony (1820-1906) is most famous for her efforts to secure women’s suffrage, but her fights for civil rights and women’s right to equality also included her efforts to secure racially integrated schools and women’s access to higher education, as well as abolitionism early in life. She was also a close ally of Elizabeth Cady Stanton. Anthony’s dream of women’s suffrage throughout the United States was achieved a few years after her death, with the 19th Amendment.
