of South Carolina from the British. The British army marched to Yorktown, Virginia, where they expected to be rescued by a British fleet. The fleet showed up but so did a larger French fleet, so the British fleet after the Battle of the Chesapeake returned to New York for reinforcements, leaving General Cornwallis trapped by the much larger American and French armies under Washington. He surrendered. The most prominent Loyalists, especially those who joined Loyalist regiments, were evacuated by the Royal Navy back to England, Canada, or other British colonies; they brought their slaves along, but lost their land. The other Loyalists who remained in the southern states became American citizens. Antebellum era (1783–1861) After the upheaval of the American Revolution effectively came to an end at the Siege of Yorktown (1781), the South became a major political force in the development of the United States. With the ratification of the Articles of Confederation, the South found political stability and a minimum of federal interference in state affairs. However, with this stability came a weakness in its design, and the inability of the Confederation to maintain economic viability eventually forced the creation of the United States Constitution in Philadelphia in 1787. Importantly, Southerners of 1861 often believed their secessionist efforts and the Civil War paralleled the American Revolution, as a military and ideological "replay" of the latter. Southern leaders were able to protect their sectional interests during the Constitutional Convention of 1787, preventing the insertion of any explicit anti-slavery position in the Constitution. Moreover, they were able to force the inclusion of the "fugitive slave clause" and the "Three-Fifths Compromise". Nevertheless, Congress retained the power to regulate the slave trade. Twenty years after the ratification of the Constitution, the law-making body prohibited the importation of slaves, effective January 1, 1808. While North and South were able to find common ground in order to gain the benefits of a strong Union, the unity achieved in the Constitution masked deeply rooted differences in economic and political interests. After the 1787 convention, two discrete understandings of American republicanism emerged. In the South, agrarian laissez-faire formed the basis of political culture. Led by Thomas Jefferson and James Madison, this agrarian position is characterized by the epitaph on the grave of Jefferson. While including his "condition bettering" roles in the foundation of the University of Virginia, and the writing of the Declaration of Independence and
