The President gave a confident, energetic performance, in which the words "je" and "France" were repeated in almost every sentence.
He addressed the mainly young crowd from a large white platform swept by red, white and blue lights.
Celebrities in the audience included actor Gerard Depardieu and the President's wife, Carla Bruni-Sarkozy. She looked on serenely, despite suggesting in a widely-mocked interview on Friday that her husband worked so hard for the country that she feared that he might "drop dead".
The Sarkozy campaign had promised new ideas to revive a campaign which has been playing, unsuccessfully, with hard-right issues such as immigration and the alleged threat to the French way of life from halal meat.
In the event, Sarkozy came up with a double-theme carefully calculated to appeal to both the nationalist right and the nationalist left: euro-bashing and protectionism.
The President claimed that he had "saved the euro and the EU" in the past 12 months. He had always been a convinced European, he said, but the EU could no longer be an "abstract" idea, served by an "elite looking at itself in the mirror". The Schengen agreement, which allows people to travel freely without border checks, "could no longer cope with the gravity" of the immigration threat, he said. He called for a government of the Schengen zone, which would bring together national governments to take emergency measures to control migrants. If progress was not made within a year, he would suspend France's membership of Schengen, to which Britain does not belong. Similarly, he said, it was time for the EU to get tough with trade partners, if we wanted to have "any factories left in 10 years' time".
