If we object to certain situations or events, mass protesting is our way of publicly and passionately expressing what we think about them, so that the powers that be sit up and take notice. Protests may involve direct action, force and even violence, though sometimes the most powerful demonstrations are the ones that that practice passive resistance. Here we look at four famous protests from the last fifty years that opened eyes and changed people’s mindsets.
