Republican Party (United States)
Founded in 1854, the GOP originally subscribed to classical liberalism and took ideological stands that were anti-slavery and pro-economic reform. Abraham Lincoln was the first Republican president in the history of the United States. The party was usually dominant over the Democrats during the Third Party System and Fourth Party System. In 1912, Theodore Roosevelt formed the Progressive ("Bull Moose") Party after being rejected by the GOP and ran as a third-party presidential candidate. Roosevelt called for many social reforms, some of which were later championed by New Deal Democrats in the 1930s. He lost the 1912 election, and when most of his supporters returned to the GOP, they were at odds with the party's new conservative economic stance; many left for the Democratic Party, and an ideological shift to the right occurred in the Republican Party. Later in the 20th century, the liberal Republican element was overwhelmed by a conservative surge begun by Barry Goldwater in 1964 and continued during the Reagan Era.
Radical Democratic Party (Bulgaria)
The Radical Democratic Party () is a liberal party in Bulgaria. The party was founded in 1902 (other sources: 1905) by Naičo Canov and other dissidents from the Democratic Party. It was banned in 1934, revived in 1944 and again banned in 1949.
In 1989 the party was re-established. It elected as its leader Elka Konstantinova. She was succeeded in 1994 by Aleksander Jordanov, and the party became an affiliated member of the Union of Democratic Forces. In 1995 the party split, with one faction remaining inside the Union of Democratic Forces, and another faction becoming an independent party. Though the party still exists, it lacks its former influence.
