William Haywood, like any outstanding revolutionary, owns his own, special place in the history of the US labor and socialist movement of the late XIX - first quarter of the XX century. Haywood was primarily a revolutionary practitioner. His struggle against reformism and tsekhovism in the labor movement, with the center-right bloc on the left flank of the socialist movement, the most active role in the class battles of workers in various industries and regions of the country left an indelible mark in the history of the US revolutionary movement, put Haywood's name on a par with the names of prominent leaders of the American proletariat.
