Napoleon decided on a military career when he was a child, winning a scholarship to a French military academy. His meteoric rise shocked not only France but all of Europe, and his military conquests threatened the stability of the world.
Napoleon was one of the greatest military commanders in history. He has also been portrayed as a power hungry conqueror. Napoleon denied being such a conqueror. He argued that he was building a federation of free peoples in a Europe united under a liberal government. But if this was his goal, he intended to achieve it by taking power in his own hands. However, in the states he created, Napoleon granted constitutions, introduced law codes, abolished feudalism, created efficient governments and fostered education, science, literature and the arts.
The siege of Toulon provided Napoleon with his first opportunity to display his ability as an artillery officer and brought him national recognition. France had gone to war with Prussia and Austria in 1792. England, having joined the struggle in 1793, had gained control of Toulon. After his distinguished part in dislodging the British, Napoleon was promoted to the rank of brigadier general. He also made the acquaintance of Augustin Robespierre, the younger brother of the powerful Maximilien, and though Napoleon was not politically a Jacobin, he derived benefits from his association with influential party members. The overthrow of the Jacobin regime on 9 Thermidor (July 1794) led to Napoleon's imprisonment in Fort Carré on August 9. When no evidence could be found linking him to the British, Napoleon was released after 10 days of confinement.
Emperor Napoleon proved to be an excellent civil administrator. One of his greatest achievements was his supervision of the revision and collection of French law into codes. The new law codes—seven in number—incorporated some of the freedoms gained by the people of France during the French revolution, including religious toleration and the abolition of serfdom. The most famous of the codes, the Code Napoleon or Code Civil, still forms the basis of French civil law. Napoleon also centralized France's government by appointing prefects to administer regions called departments, into which France was divided.
The Napoleonic era changed warfare because as France expanded its borders under Napoleon’s control, he reorganized the governments, the postal services, and the system for collecting taxes. Napoleon introduced the first printing presses; created a health department, built new hospitals for the poor. Napoleon proved that through a sophisticated education came sophisticated weaponry. The forefront of his success was fighting with his men as well as fighting for them.
