The Bull Moose Party, officially the Progressive Party, was a renegade social group in the United States that supported former president Theodore Roosevelt as its democratic nominee in 1912; the group's actual title and broad ideals were resurrected 12 years later. A National Republican Progressive League was founded in 1911 by Wisconsin Senator Robert M. La Follette to oppose the established liberalism of the mainstream Republican Party, which was headed by President William Howard Taft. The very next year, the gathering renamed itself the Progressive Party, and on August 7, 1912, it held a conference in which it selected Roosevelt for the head of state and Governor Hiram W. Johnson of California for vice president, as well as calling for a modification of the ideological electing system and a forceful cultural legislation scheme.
