The premise here is that there existed a specific moment in the history of France —and, one might speculate, of other European societies—when a popular insurrection in the capital was capable of bringing down the national government, virtually overnight and irrespective of public sentiment in the provinces. In the face of such sudden outbursts, not even those regimes that appeared most firmly entrenched proved to be secure. The most striking instances, and the ones that will be the exclusive focus of attention here, occurred in Paris during the early years of the French Revolution of 1789 as in 1830 and 1848, when the urban crowd was able, if only for a time, to impose new institutions and policies upon the nation. In general, the rural population proved acquiescent, but the will of the capital initially held sway even when the numerical majority living in the countryside seemed resistant to the change.
