Can someone give me a Introductory Paragraph?

I would disagree with this premise. The goals of the Revolution were lost during the Reign of Terror, and were not returned into the practice during Directory, Consulate, and Napoleonic Empire. It was the Reign of Terror and the Jacobin leadership with Robespierre in the lead that undermined three pillars of the democracy: freedom of press, freedom of speech, and freedom of religion. This was all gone by fall of 1793, ten years before Napoleon crowning as an emperor. Also it was Robespierre and his supporters who suspended a constitution approved by popular vote under premise that the fatherland was in danger.

Napoleon was an enlightened dictator. He enforced censorship, state control over education; but also supported bureaucracy, and implemented many social reforms that were demanded by Revolution. Napoleon find a compromise between the best of the Revolution and the Ancient Regime, and renewed ties with the Catholic church that was important part of the life for rural France. This gave him a tremendous support among rural population who never in first place supported radical ideas of the Paris Commune.

The transformation from I. Republic to the Empire happened during the Directory (1795-1799), which coincide with two trends. First was widespread collapse of the French economy by hyperinflation that destroyed savings, faith in currency, and capital. Second trend established already by Robespierre in the winter of 1793/1794 was destroying the representatives of the poorest people. This masses of urban poor felt that the Revolution had betrayed them and they gained nothing from it. Their hungry riots were suppressed by May 1795 and they were excluded from universal suffrage (new law allowed to cast a vote after certain amount of taxes were paid, which excluded the poor). This was also reason why the poor were against Directory and supported Napoleon and Army as the only institution to be trusted.
