Gradual Emancipation in Pennsylvania

Pennsylvania adopts the first "gradual emancipation" law. Under this statute, no new slaves can be brought into the state, and the children of all existing slaves will be freed when they turn 28 (a far longer period of service than indentured servitude had required for whites). Slaves born before the passage of this act are condemned to a lifetime of servitude. Only those born after 4 July 1780 will be born free.

1788

Slave Trade Forbidden

New York, Massachusetts, Connecticut, and Pennsylvania forbid their citizens from participating in the slave trade.

1792

Kentucky Joins With Slaves

Kentucky is admitted as the first new slave state.

1793

Fugitive Slave Law

Congress passes the Fugitive Slave Law. The statute enforces a measure in the Constitution that denies a jury trial to an alleged fugitive slave and authorizes any federal or state judge to decide that individual's fate. Many northern leaders oppose the law, which they interpret as a direct assault on personal liberty.

May 1, 1793

Eli Whitney Invents Cotton Gin

Eli Whitney invents the cotton gin, which allows for the cultivation of short- staple cotton and revolutionizes the industry, dramatically increasing its profitability and the land areas that can be utilized for growing the crop.

New York Gradual Emancipation

New York passes a gradual emancipation statute.

1799

Virginia and Kentucky Resolutions

Legislators from Virginia and Kentucky adopt a series of resolutions in an act of protest against the Federalist Alien and Sedition Acts passed in 1798. The resolutions, written by Vice President Thomas Jefferson and Congressman James Madison, denounce the Acts as unconstitutional, and assert the right of states to reject any federal law that violates the Constitution. In later years, South Carolina will interpret these resolutions as an affirmation of state power to nullify federal law.

Jan 1, 1800

Gabriel Prosser Plot

Gabriel Prosser conspires to seize Richmond, Virginia with a large force of perhaps 1,000 armed slaves and then proceed with a general slaughter of whites. The plot is uncovered; 25 of the conspirators are executed and ten others deported to the West Indies.

Dec 15, 1814

Hartford Convention

A group of New England Federalists gathers in Hartford, Connecticut to discuss long-held grievances regarding the power of slaveholders in the federal government. Known as the "Hartford Convention," the group calls for several amendments to the Constitution, including a requirement for a two-thirds vote of Congress for the admission of new states and the elimination of the three-fifths clause, which gives an advantage to slave-holding states in congressional representation and presidential elections. The Hartford Convention fails in its endeavors and its bold moves prove to be a deathblow to the party, which cannot shake charges that it is unpatriotic. It is later erroneously rumored that the Hartford Convention represents the first group to call for secession; this is not true. The Convention only contends that states have the right to interpose their authority if the federal government violates the Constitution.

1817

New York Emancipation

New York State enacts a law, effective 4 July 1827, freeing all blacks who would not have been freed before then by the gradual emancipation act of 1799.

Mar 2, 1820

Missouri Compromise of 1820

The House and Senate are deadlocked over the question of whether to admit Missouri as a slave state. There is some fear of civil war. As a compromise, Congress adopts an amendment that there shall be no restriction on slavery in Missouri, but the institution will be prohibited from Louisiana Territory north of 36º30' latitude. Protests continue as critics seek to refuse Missouri's admission unless the state passes legislation to provide for gradual emancipation.

1820

Slave Trade as Piracy

Congress defines the slave trade as piracy.

Aug 10, 1821

Leaders in South Carolina assert that such incarcerations are necessary in order to protect slavery in the state.

Nov 1828

1832

Virginia Debates Slavery

On the heels of Nat Turner's violent rebellion, the Virginia legislature debates and rejects a bill to consider the gradual abolition of slavery. Some southern whites worry that the uprising is a sign that slavery will only lead to bloodshed and is, therefore, not worth the danger. On the other hand, a majority of Virginians—and southerners—seek to maintain slavery and aggressively regulate and discipline slaves to suppress any attempt at future rebellion.

Nov 1832

Jackson Re-elected

Democrat Andrew Jackson is re-elected president of the United States.

Jan 1, 1832

1833

Compromise Tariff of 1833

Congress adopts the Compromise Tariff of 1833, which is proposed by Senators Henry Clay and John C. Calhoun as a resolution to the Nullification Crisis. Calhoun has developed a theory that states have the right to nullify federal legislation if it runs counter to their interests. He proposes this step in response to ever steeper congressional tariffs passed in 1828 and 1832. To avoid the impending crisis between President Jackson and South Carolina, Senator Henry Clay spearheads a successful compromise measure in Congress to lower the 1832 tariff.

Mar 2, 1836

Texas Declares Independence

The Texas Declaration of Independence is enacted, creating the Republic of Texas (otherwise known as the "Lone Star Republic"). The U.S. government refuses to recognize Texas because it does not want to agitate sectional strife; abolitionists oppose Texas's admission to the Union because they know it will become a slave state. But the U.S. does commence secret negotiations with Texas on annexation in 1843.

Nov 1844

James Polk Elected

James K. Polk wins the presidency by a margin of just 1.4% of the popular vote; the antislavery Liberty Party wins 65,000 votes in the presidential election. It is hardly close to a popular majority, but it is enough to deprive the Whigs of taking the state of New York, and that determines the election of Democrat James K. Polk instead of the Whig candidate, Henry Clay.

Dec 1, 1844

John Quincy Adams Repeals Gag Rule

RANGEEND_GAG_RULE Representative John Quincy Adams calls for a repeal of the gag rule. All the northern Whigs and four southern Whigs support Adams, as do 78% of northern Democrats. The gag rule is dead.

The fugitives in question are denied a jury trial.

Jun 12, 1845

During the Civil War, President Lincoln will meet Stowe in the White House and reportedly say to her (in so many words): "So you're the little lady that caused this great big war."

May 24, 1854

Anthony Burns Uproar

Abolitionist Wendell Phillips and other antislavery advocates attack a federal courthouse in Boston, Massachusetts where Anthony Burns, a fugitive slave, is held.

President Pierce orders Burns's return as an example to others that he will enforce the Fugitive Slave Act.

1854

Kansas-Nebraska Act

The Kansas-Nebraska Bill passes, largely thanks to Stephen A. Douglas, the Democratic senator from Illinois.

Controversy over the bill will drive a wedge into the Democratic Party, shatter Whig unity, and spur the creation of the Republican Party in the North.

1855

Capitol Statue Controversy

American sculptor Thomas Crawford is asked to design a work of art to crown the Capitol's dome in Washington, D.C. He proposes a female figure wearing a liberty cap. Secretary of War Jefferson Davis, a slaveholder from Mississippi, objects to the idea because the image, he says, may imply a connection between slaves' desire for freedom and the liberty of free-born Americans. A feathered helmet replaces the liberty cap.

Business Failures Amid Panic

A new economic panic begins leading to business failures and widespread unemployment.

Debate Over Kansas

President James Buchanan tries and fails to admit Kansas as a slave state.

The admission bill stalls in the House. Kansas will finally be admitted to the Union as a free state in 1861.

Aug 21, 1858

Lincoln Douglas Debates

During the Illinois senatorial race, Democratic incumbent Stephen A. Douglas and Republican candidate Abraham Lincoln engage in a series of fiery debates. For four months, the two men travel all across the state, speaking before thousands of spectators. They argue primarily about whether, in Lincoln's words, "a house divided against itself cannot stand" and whether slavery ought to be placed "in the course of ultimate extinction"; that is, if the Wilmot Proviso should be revived and slavery should forevermore be banned from all U.S. territories. Lincoln will ultimately lose the election, but his fierce attacks on the Democratic agenda will gain him national fame. Two years later, the Republican Party will nominate him for the highest office in the land.

Oct 16, 1859

John Brown Raid on Harpers Ferry

Under the cover of darkness, radical abolitionist John Brown crosses the Potomac River with twenty-one men, including five blacks.
