May 1st may not be the typical holiday, filled with pomp and fun but it is a day that shook the world. Back in the 19th century, May 1st was the beginning of what history calls as the Workers' Movement.

Known popularly as the International Workers' Day, May 1st marks the commemoration of Chicago's Haymarket Affair that took place in 1886, as peacefully striking workers were blown to shards by the bomb that exploded.

Taking the event as a base for furthering working class consciousness, the then Socialist parties of the world formally recognized this epic event as May Day at their Second International's Congress in 1891.
