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. Historians have moved back in time emphasizing the Progressive reformers at the municipal and state levels in the 1890s.
