Workers' May Day parade on the Senate Square in 1912. In the 1890s, the worker population began celebrating May Day festivities, along with the corresponding marches. The annual May Day march first started to take the form of a protest with the “drinking strike” movement of 1898. In the 20th century, civic addresses, mass meetings, banners, and other symbols became integral May Day markers. The Senate Square became the central destination and often the end point of the marches.
