Napoleon had no choice but to abdicate in favor of his son. However, the Allies refused to accept this. Napoleon abdicated without conditions on April 11, 1814. Before his official abdication, Napoleon attempted suicide with a pill but it did not work. In the Treaty of Fontainebleau the victors exiled him to Elba, an island of 12,000 inhabitants in the Mediterranean. The Allies allowed Napoleon to keep an imperial title "Emperor of Elba" and an allowance of 2 million francs a year. Napoleon even requested a 21 gun salute as emperor of the island of Elba. Many delegates feared that Elba was too close to Europe to keep such a dangerous force.
