The Industrial Workers of the World (IWW), commonly known as the Wobblies, were among the most well-respected and largest unions in the United States in the early 20th century. Having organized the first major automobile industry strike as well as major coalfield and transit workers strikes, the IWW has a history of being a fierce advocate for the worker. Long before most other unions, IWW welcomed women, African-Americans, and immigrants into their ranks, making the Wobblies among the most progressive organizations of the era. As the only comprehensive history of the IWW, this chronicle anthologizes nearly every important document and essay in the Wobblies' rich history. The impact of the IWW has reverberated through the history of unions and organized labor, and this is their story.
