After lying dormant for the winter, the Occupy Wall Street movement re-emerged on May 1 in a series of U.S.-wide protests. May 1, known internationally as May Day, is a day meant to commemorate the efforts and struggles of laborers around the world.

The Occupy movement began on September 17, 2011, when hundreds of people descended on the streets of New York City's financial district. The movement aim to raise awareness about the role financial institutions played in the continued economic downturn affecting the world markets, and the alleged lack of accountability on the part of the banks and financial institutions responsible for the crash.
