Incidence
In the twentieth century some revolutions that might be cited (excluding wars of independence) are those of the Communists in Russia, China, Yugoslavia and Cuba, and that of the Islamic fundamentalists in Iran. A number of others (for instance, Ethiopia) can be listed, mainly Communistic. There are also revolutionary movements whose motives are linguistic or ethnic - as the Basque and Quebecôis among others - or specifically racial.
Counter-claim
When, in the course of human events, people are oppressed by their governments, and by the structural violence perpetuated by privileged classes; when their voice is not heard and they are mocked by token changes and platitudinous political promises; when their rights to adequate food and shelter, to medical care and employment, and to freedom of speech are ignored; then direct and forceful action against the criminal classes of rulers, bureaucrats, the rich and all their minions is required to restore justice. Revolution means return; judicious revolution with a minimum of violence means a return to the spirit of the laws of the nation. The elimination of central government by full anarchy, therefore, is the most spiritual form of revolution.
