People power
"People Power" is a political term denoting the populist driving force of any social movement which invokes the authority of grassroots opinion and willpower, usually in opposition to that of conventionally organised corporate or political forces. "People power" can be manifested as a small-scale protest or campaign for neighborhood change; or as wide-ranging, revolutionary action involving national street demonstrations, work stoppages and general strikes intending to overthrow an existing government and/or political system. It may be nonviolent, as was the case in the 1986 Philippines revolution which overthrew the Marcos régime, or may resort to violence, as happened in Libya in 2011. The term was first used by members of the 1960s "flower power" movement which initially protested against the Vietnam War.
