The SLP suffered an organizational split in 1889 over the matter of tactics, pitting a group dedicated to political action headed by Wilhelm Rosenberg against others favoring an orientation based upon the development of socialist influence in the trade unions.
There was subsequently some effort towards unity of the two factions, with Thomas J. Morgan put forward for Mayor of Chicago in 1891 as the joint nominee of the official SLP and the Rosenberg organization.
