The Republican Party in the United States…
February 1854 CE
The Republican Party will quickly become the principal opposition to the dominant Democratic Party and the briefly popular Know Nothing Party.
The main cause is opposition to the Kansas–Nebraska Act, which repeals the Missouri Compromise by which slavery is kept out of Kansas.
The Northern Republicans see the expansion of slavery as a great evil.
The first public meeting of the general anti-Nebraska movement, at which the name Republican is suggested for a new anti-slavery party, is held in a schoolhouse in Ripon, Wisconsin.
The name is partly chosen to pay homage to Thomas Jefferson's Republican Party.
