How did political rebellions affect the political structures and ideologies around the world?

Political rebellions lead to many extreme forms of government for the time eras, wither it be the English in the glorious revolution which led to a parliamentary monarchy, prefacto of democracy for the isles or in Europe in the 30's in which powers such as Mussolini or Hitler and Stalin took power. Many states along that time also flipped to extremist ideology's from political rebellions

Democracy and darwinism would be my answer.
