The happy idea of using a proletarian holiday celebration as a means to attain the eight-hour day was first born in Australia. The workers there decided in 1856 to organize a day of complete stoppage together with meetings and entertainment as a demonstration in favor of the eight-hour day.

The day of this celebration was to be April 21. At first, the Australian workers intended this only for the year 1856. But this first celebration had such a strong effect on the proletarian masses of Australia, enlivening them and leading to new agitation, that it was decided to repeat the celebration every year.

In fact, what could give the workers greater courage and faith in their own strength than a mass work stoppage which they had decided themselves? What could give more courage to the eternal slaves of the factories and the workshops than the mustering of their own troops? Thus, the idea of a proletarian celebration was quickly accepted and, from Australia, began to spread to other countries until finally it had conquered the whole proletarian world.
