The Progressive Republican Party emerged in the early 20th century as a faction within the Republican Party that sought to address social issues and promote reforms. It was characterized by its support for progressive policies, including labor rights, women's suffrage, and anti-corruption measures. Key figures included Theodore Roosevelt, who championed these reforms during his presidency. The party aimed to challenge the influence of big business and promote greater government intervention in the economy. It played a significant role in the Progressive Era, a time marked by widespread social activism and political reform in the United States, ultimately influencing the broader political landscape.
