Occupy Wall Street (OWS) was a protest movement against economic inequality that began on this day in Zuccotti Park, located in New York City's Wall Street financial district, in 2011. It gave rise to the wider Occupy movement in the United States and other countries.

The OWS slogan, "We are the 99%", refers to income and wealth inequality in the U.S. between the wealthiest 1% and the rest of the population. To achieve their goals, protesters acted on consensus-based decisions made in general assemblies which emphasized redress through direct action.
