Ahmed White, author of "Under the Iron Heel: The Wobblies and the Capitalist War on Radical Workers." The term 'Wobblies' in the subtitle refers to members of the I.W.W. - the Industrial Workers of the World - a radical union formed in 1905 that sought to overturn capitalism in order to eliminate the brutal working conditions of millions of U.S. factory workers in early 20th century America. The union was ultimately destroyed thanks to internal division as well as a concerted attack from government officials, law enforcement, and capitalist leaders.
