Introduction

Democratic Party, one of the two main political parties of the United States. Its origins can be traced to the coalition formed behind Thomas Jefferson in the 1790s to resist the policies of George Washington’s administration. This coalition, originally called the Republican, and later the Democratic-Republican Party, split into two factions during the presidential campaign of 1828. One, the National Republican Party, was absorbed into the Whig Party in 1834; the other became the Democratic Party.
