Today, it may seem impossible to imagine the U.S. government without its two leading political parties, Democrats and Republicans. But in 1787, when delegates to the Constitutional Convention gathered in Philadelphia to hash out the foundations of their new government, they entirely omitted political parties from the new nation鈥檚 founding document.

This was no accident. The framers of the new Constitution desperately wanted to avoid the divisions that had ripped England apart in the bloody civil wars of the 17th century. Many of them saw parties鈥攐r 鈥渇actions,鈥 as they called them鈥攁s corrupt relics of the monarchical British system that they wanted to discard in favor of a truly democratic government.

鈥淚t was not that they didn鈥檛 think of parties,鈥 says Willard Sterne Randall, professor emeritus of history at Champlain College and biographer of six of the Founding Fathers. 鈥淛ust the idea of a party brought back bitter memories to some of them.鈥

George Washington鈥檚 family had fled England precisely to avoid the civil wars there, while Alexander Hamilton political parties 鈥渢he most fatal disease鈥 of popular governments. James Madison, who worked with Hamilton to defend the new Constitution to the public in the Federalist Papers, wrote in that one of the functions of a 鈥渨ell-constructed Union鈥 should be 鈥渋ts tendency to break and control the violence of faction.鈥

But Thomas Jefferson, who was serving a diplomatic post in France during the Constitutional Convention, believed it was a mistake not to provide for different political parties in the new government. 鈥淢en by their constitutions are naturally divided into two parties,鈥欌 he .

In fact, when Washington ran unopposed to win the first presidential election in the nation鈥檚 history, in 1789, he chose Jefferson for his Cabinet so it would be inclusive of differing political viewpoints. 鈥淚 think he had been warned if he didn't have Jefferson in it, then Jefferson might oppose his government,鈥 Randall says.

With Jefferson as secretary of state and Hamilton as Treasury secretary, two competing visions for America developed into the nation鈥檚 first two political parties. Supporters of Hamilton鈥檚 vision of a strong central government鈥攎any of whom were Northern businessmen, bankers and merchants who leaned toward England when it came to foreign affairs鈥攚ould become known as the Federalists. Jefferson, on the other hand, favored limited federal government and keeping power in state and local hands. His supporters tended to be small farmers, artisans and Southern planters who traded with the French, and were sympathetic to France.

Though he had sided with Hamilton in their defense of the Constitution, Madison strongly opposed Hamilton鈥檚 ambitious financial programs, which he saw as concentrating too much power in the hands of the federal government. In 1791, Madison and Jefferson joined forces in forming what would become the Democratic-Republican Party (forerunner of today鈥檚 Democratic Party) largely in response to Hamilton鈥檚 programs, including the federal government鈥檚 assumption of states鈥 debt and the establishment of a national banking system.

By the mid 1790s, Jefferson and Hamilton had both quit Washington鈥檚 Cabinet. Meanwhile, the Democratic-Republicans and Federalists spent much of the first president鈥檚 second term bitterly attacking each other in competing newspapers over their opinions of his administration鈥檚 policies.

When Washington stepped aside as president in 1796, he memorably in his farewell address of the divisive influence of factions on the workings of democracy: 鈥淭he common and continual mischiefs of the spirit of party are sufficient to make it the interest and duty of a wise people to discourage and restrain it.鈥

鈥淗e had stayed on for a second term only to keep these two parties from warring with each other,鈥 Randall says of Washington. 鈥淗e was afraid of what he called 鈥榙isunion.鈥 That if the parties flourished, and they kept fighting each other, that the Union would break up.鈥

By that time, however, the damage had been done. After the highly contentious election of 1796, when John Adams narrowly defeated Jefferson, the new president moved to squash opposition by making it a federal crime to criticize the president or his administration鈥檚 policies. Jefferson struck back in spades after toppling the unpopular Adams four years later, when Democratic-Republicans won control of both Congress and the presidency. 鈥淗e fired half of all federal employees鈥攖he top half,鈥 Randall explains. 鈥淗e kept only the clerks and the customs agents, destroying the Federalist Party and making it impossible to rebuild.鈥

While the Federalists would never win another presidential election, and disappeared for good after the War of 1812, the two-party system revived itself with the rise of Andrew Jackson鈥檚 Democratic Party by the 1830s and firmly solidified in the 1850s, after the founding of the Republican Party. Though the parties鈥 identities and regional identifications would shift greatly over time, the two-party system we know today had fallen into place by 1860鈥攅ven as the nation stood poised on the brink of the very civil war that Washington and the other Founding Fathers had desperately wanted to avoid.
