The Progressive Party, popularly nicknamed the Bull Moose 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 turned rival, incumbent president William Howard Taft. The new party was known for taking advanced positions on progressive reforms and attracting leading national reformers. The party was also ideologically deeply connected with America's radical-liberal tradition.
