It is a protest which does not employ violence as a way of getting the message across. Some means of achieving this could be petitions, lobbying through email, letters or media outlets, or boycotting. Demonstrations, marches and similar can also be a form of non-violent protest, but often become violent as they progress. One example of an effective non-violent protest was the Montgomery Bus Boycott, where coloured people refused to use the buses in Montgmoery, Alabama to protest about segregation on the service. After almost a year, loss of revenue forced the company to desegregate the buses and allow coloured people to sit at the front.
