During the late nineteenth and the early twentieth centuries, socialism attracted many in the United States. Socialists called for an economic system that removed greed from the people. Rather than working to attain the most wealth, socialists hoped that the U.S. public at large would work together to benefit the common good. They also desired public ownership of utilities and transportation systems. Socialists did not necessarily want to make everyone in the U.S. politically, economically, and socially equal; rather, they wanted to have people in the U.S., as a whole, working together to benefit everyone. Some people in the U.S. would be deserving of more than other citizens, but no U.S. citizen should prosper by denying his or her fellow citizen the basic necessities of life.
The socialists' message became especially welcome among the working class, including factory workers who endured harsh working and living conditions, and in 1912, as many as one-third of the American Federation of Labor's members favored socialism. Socialism became so popular that the Socialist Party of America originated. Among its more prominent members was Eugene V. Debs. Another prominent supporter of socialism during this era was author and muckraker Upton Sinclair. Sinclair hoped to convince the U.S. public through his novels, including The Jungle and Oil!, to adopt socialism. Due to socialism's increasing popularity, both the Republican and the Democratic Parties reached out to workers and sought to improve working conditions.
In Ohio, socialists attained limited success. Progressives, who sought to improve the working and living conditions of people in the United States, originated in the state before the socialists gained a foothold. In 1911, socialists managed to gain control of the mayoral seats of a few communities, including Canton, Lima, Barberton, and Lorain, but socialism's popularity quickly declined in the state, as many prominent socialists opposed United States involvement in World War I. Socialists remained active in the United States through the 1920s and 1930s, but their numbers quickly dwindled during this same period.
