The writings of Napoleon I and his contemporaries' testimonies reveal the image of a statesman more taken up with action than theories and whom circonstances have made go through different stages in his political convictions. During his youth, he takes up all the ideas of the eighteenth century, even to their contradictions, though the temper of the leader to come, sometimes shows through already. During the Consulate - a time of dissimulation - he tries to conciliate around him the most antagonistic ideas in order to strengthen his popular dictatorship. When at the height of his glory - about 1808-1811 - he longs to enter the «European Concert» white building a universal Empire, and he thinks of reviving the old regime society, white not admitting any intermediary between the Nation and himself. Defeated, then deported, he clearly analyses the causes of his failure and makes the most of future by reappealing to the ideas of the Revolution.
