Radical labor organizer and anarchist Lucy Parsons leads hunger march in Chicago; IWW songwriter Ralph Chaplin writes "Solidarity Forever" for the march - 1915

Wobblie Ralph Chaplin, in Chicago for a demonstration against hunger, completes the writing of the labor anthem “Solidarity Forever” on this date in 1915. He’d begun writing it in 1914 during a miner’s strike in Huntington, W. Va. The first verse:
When the union's inspiration through the workers' blood shall run,
There can be no power greater anywhere beneath the sun;
Yet what force on earth is weaker than the feeble strength of one,
But the union makes us strong - 1915
