Progressivism began as a social movement and grew into a political movement. The early progressives rejected Social Darwinism. In other words, they were people who believed that the problems society faced (poverty, violence, greed, racism, class warfare) could best be addressed by providing good education, a safe environment, and an efficient workplace.Social reformers, like Jane Addams, and journalists, like Jacob Riis and Ida Tarbel, were powerful voices for progressivism. They concentrated on exposing the evils of corporate greed, combating fear of immigrants, and urging Americans to think hard about what democracy meant. Other local leaders encouraged Americans to register to vote, fight political corruption, and let the voting public decide how issues should best be addressed (the initiative, the referendum, and the recall). On a national level, progressivism gained a strong voice in the White House when Theodore Roosevelt became president in 1901.
