Reply #17: Looks like it's the left that has a history of black blocing. That is just great.

The first recorded use of the tactic in United States of America was in 1989 at a protest at the Pentagon. Other early use in the US were the Earth Day Wall Street Action in 1990 and the February 1991 protests against the Gulf War. These were initiated by Love and Rage, a North American revolutionary anarchist organization active in New York. Black blocs gained significant media attention when a black bloc caused damage to property of GAP, Starbucks, Old Navy, and other retail locations in downtown Seattle during the 1999 anti-WTO demonstrations<8>. They were a common feature of subsequent anti-globalization protests.<9>

Other groups that have engaged in similar forms of action include Radical Anti-Capitalist Blocs, Anti-Racist Action, and Anti-Fascist Action.
