Choose one dynamic, a political choice, a change in society, etc. that strikes you as showing with particular clarity that revolution was less of a possibility in Europe in 1850–1875. You can refer to economic or social developments; to the growing possibility of reform; to governments’ wielding of wars of choice; to repression, or, conversely, to liberalization; to the creation of “national stories,” etc. You can also refer to counterexamples! At any rate, explain in your own words why you chose your example. But do refer to precise facts.
