Progressive Party (United States, 1912)
The Progressive Party was a third party in the United States formed in 1912 by former President Theodore Roosevelt after he lost the presidential nomination of the Republican Party to his former protégé, incumbent President William Howard Taft. The new party was known for taking advanced positions on progressive reforms and attracting some leading reformers. After the party's defeat in the 1912 presidential election, it went into rapid decline, disappearing by 1918. The Progressive Party was popularly nicknamed the "Bull Moose Party" since Roosevelt often said that he felt "strong as a bull moose" both before and after an assassination attempt on the campaign trail.

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.
