  Political parties have dominated American politics for most of the nation's history. Though the Founding Fathers generally spurned political parties as divisive and disruptive, and their rise had not been anticipated when the U.S. Constitution was drafted in 1787, organized political parties developed in the U.S. in the mid-1790s nonetheless. They evolved from political factions, which began to appear almost immediately after the Federal government came into existence. Those who supported the Washington administration were referred to as "pro-administration" and would eventually form the Federalist Party, while those in opposition largely joined the emerging Democratic-Republican Party.
  
  Greatly concerned about the very real capacity of political parties to destroy the fragile unity holding the nation together, Washington remained unaffiliated with any political faction or party throughout his eight-year presidency. He was, and remains, the only U.S. president never to be affiliated with a political party. Since Washington, every U.S. president has been affiliated with a political party at the time of assuming office, and, since 1869, every president has been a member of either the Republican or Democratic Parties.
