Anarchism grew in popularity and influence as part of the anti-war , anti-capitalist , and anti-globalisation movements . Maia Ramnath described those social movements that employ the anarchist framework ( leaderless , direct democracy ) but do not call themselves anarchists as anarchists with a '' lowercase " a " '' , while describing more traditional forms of anarchism with a '' capital " A " '' . Anarchists became known for their involvement in protests against meetings such as the World Trade Organization in Seattle in 1999 , Group of Eight in 2001 and the World Economic Forum , as part of anti-globalisation movement . Some anarchist factions at these protests engaged in rioting , property destruction , and violent confrontations with police . These actions were precipitated by ad hoc , leaderless , anonymous cadres known as black blocs . Other organisational tactics pioneered during this period include security culture , affinity groups and the use of decentralised technologies such as the Internet
