Anarchism in the United States began in the mid-19th century and started to grow in influence as it entered the American labor movements, growing an anarcho-communist current as well as gaining notoriety for violent propaganda of the deed and campaigning for diverse social reforms in the early 20th century. By around the start of the 20th century, the heyday of individualist anarchism had passed and anarcho-communism and other social anarchist currents emerged as the dominant anarchist tendency.
