View source for May Day

May Day has competed with Labor Day as a workers' holiday in the United States from the late nineteenth century. Both celebrations have deep roots in the struggle for the eight hour day in the 1880s, though May Day's origins go back to European agricultural spring festivals. Most of the images here are from New York City, where Union Square played a central role for both holidays. 

Tens of thousands of people marched in the annual May Day parades in Union Square in the 1930s, though by accident of history we have a larger number of photographs and pamphlets here from 1948, when the numbers were greatly diminished.
