Josephine's entreaties had been fruitless, or Bonaparte had, at least, only yielded to them in their literal sense. She had said: "I entreat you, do not make yourself a king!" Bonaparte did not make himself king, he made himself emperor. He did not take up the crown that had fallen from the head of the Bourbons; he created a new one for himself--a crown which the French people and Senate had, however, offered him. The revolution still stood a threatening spectre behind the French people; its return was feared, and, since the discovery of the conspiracy of Georges, Moreau, and Pichegru, the people anxiously asked themselves what was to become of France if the conspirators should succeed in murdering Bonaparte; and when the republic should again be sent adrift, without a pilot, on the wild sea of revolution. The people demanded that their institutions should be securely established and maintained, and believed that this could only be accomplished by a dynasty--by a monarchical form of government. The consulate for life must therefore be changed into an hereditary empire. Had not Bonaparte himself said: "One can be emperor of a republic, but not king of a republic; these two terms are incompatible!" They desired to make Napoleon emperor, because they flattered themselves that in so doing they should still be able to preserve the republic. On the 18th of May, of the year 1804, the plan that had been so long and carefully prepared was carried into execution. On the 18th of May, the Senate repaired to St. Cloud, to entreat Bonaparte, in the name of the people and army, to accept the imperial dignity, and exchange the Roman chair of a consul for the French throne of an emperor. Cambacérès, the late second consul of the republic, stood at the head of the Senate, and upon him devolved the duty of imparting to Bonaparte the wishes of the French people. Cambacérès--who, as a member of the Convention, had voted for the condemnation of Louis XVI., in order that royalty should be forever banished from French soil--this same Cambacérès, was now the first to salute Bonaparte with "imperial majesty," and with the little word, so full of significance, "sire." He rewarded Cambacérès, for this by writing to him on the game day, and appointing him high constable of the empire, as the first act of his imperial rule. In this letter, the first document in which Bonaparte signed himself merely Napoleon, the emperor retained the republican style of writing. He addressed Cambacérès, as "citizen consul," and followed the revolutionary method of reckoning time, his letter being dated "the 20th Floréal, of the year 12."
