The Progressive Era was a period of widespread social activism and political reform across the United States, from the 1890s to 1920s. The main objective of the Progressive movement was eliminating corruption in government. The movement primarily targeted political machines and their bosses.By taking down these corrupt representatives in office a further means of direct democracy would be established.n the 1940s typically historians saw the Progressive Era as a prelude to the New Deal and dated it from 1901 (when Roosevelt became president) to the start of World War I in 1914 or 1917.
