Progressive Party (United States, 1912)
As a member of the Republican Party, Roosevelt had served as President from 1901 to 1909, becoming increasingly progressive in the later years of his presidency. In the 1908 presidential election, Roosevelt helped ensure that he would be succeeded by Secretary of War Taft. After Taft took office, he hewed closer to the conservative wing of the party and this and other actions alienated Roosevelt from his former friend. Progressive Republican leader Robert La Follette had already announced a challenge to Taft for the 1912 Republican nomination, but many of his supporters shifted to Roosevelt after the former President decided to seek a third presidential term, which was permissible under the Constitution prior to the ratification of the Twenty-second Amendment. At the 1912 Republican National Convention, Taft narrowly defeated Roosevelt for the party's presidential nomination. After the convention, Roosevelt, Frank Munsey, George Walbridge Perkins and other progressive Republicans established the Progressive Party and nominated a ticket of Roosevelt and Hiram Johnson of California at the 1912 Progressive National Convention. The new party attracted several Republican officeholders, although nearly all of them remained loyal to the Republican Party—in California, Johnson and the Progressives took control of the Republican Party.
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.
