Brissenden, The Launching of the Industrial Workers of the World, page 41. Whatever visions of world conquest the militants may at first have fostered were soon shattered by internal strife. There were unreconcilable elements in the body: those who regarded the political aspect as paramount and industrial unions as allies of socialism; those who regarded the forming of unions as paramount and politics as secondary; and those who regarded all forms of political activity as mere waste of energy. The first two groups were tucked under the wings of the Socialist party and the Socialist Labor party. The third group was frankly anarchistic and revolutionary. In the fourth annual convention the Socialist factions withdrew, established headquarters at Detroit, organized what is called the Detroit branch, and left the Chicago field to the revolutionists. So socialism "pure and simple," and what amounts to anarchism "pure and simple," fell out, after they had both agreed to disdain trade unionism "pure and simple." This shift proved the great opportunity for Haywood and his disciples. Feeling himself now free of all political encumbrances, he gathered around him a small group of enthusiastic leaders, some of whom had a gift of diabolical intrigue, and with indomitable perseverance and zeal he set himself to seeking out the neglected, unskilled, and casual laborer. Within a few years he so dominated the movement that, in the public mind, the I. W. W. is associated with the Chicago branch and the Detroit faction is well-nigh forgotten. As a preliminary to a survey of some of the battles that made the I. W. W. a symbol of terror in many communities it will be well to glance for a moment at the underlying doctrines of the organization. In a preamble now notorious it declared that "the working class and the employing class have nothing in common. There can be no peace so long as hunger and want are found among millions of working people, and the few who make up the employing class have all the good things of life. Between these two classes a struggle must go on until the workers of the world as a class take possession of the earth and the machinery of production and abolish the wage system."
