In political
science, a
revolution is a fundamental and relatively sudden change in political power and political
organization which occurs when the population revolts against the
government, typically due to perceived
oppression (political, social, economic).
Revolutions have occurred throughout
human history and vary widely in terms of methods, duration, and motivating
ideology. Their results include major changes in culture,
economy, and socio-political institutions, usually in response to perceived overwhelming autocracy or plutocracy.
A
black bloc is a tactic used by anti-capitalist protesters who wear black clothing, ski masks, scarves, sunglasses, motorcycle helmets with padding, or other face-concealing and face-protecting items. The clothing is used to conceal wearers' identities and hinder criminal prosecution by making it difficult to distinguish between participants. It is also used to protect their faces and eyes from pepper spray, which is used by police during protests or civil unrest. The tactic allows the group to appear as one large unified mass.
Black bloc participants are often associated with
anarchism,
anarcho-communism,
communism, libertarian
socialism, antifascism, or the anti-
globalization movement.

The tactic was developed in the 1980s in the European autonomist movement's protests against squatter evictions,
nuclear power, and restrictions on abortion, as well as other influences. Black blocs gained broader media attention outside
Europe during the 1999 Seattle WTO protests when a
black bloc damaged property of various
multinationals.
Diversity of tactics is a phenomenon wherein a social movement makes periodic use of force for disruptive or defensive purposes, stepping beyond the limits of
nonviolence, but also stopping short of total militarization. It also refers to the theory which asserts this to be the most effective strategy of
civil disobedience for social change.
Diversity of tactics may promote
nonviolent tactics, or armed
resistance, or a range of methods in between, depending on the level of
repression the political movement is facing.
