Britain's interests laid with the Ottoman Empire during the Crimean War. Napoleonic era The Napoleonic era (1799–1815) brought some relief to the faltering Ottoman Empire. It distracted Russia from further advances. Napoleon invaded Egypt but his army was trapped there when the British decisively defeated the French fleet at Aboukir Bay. A peace interlude in 1803 allowed the army to return to France. To secure his own domination and to render the rest of Europe virtually powerless, Napoleon established an alliance with Russia by concluding the Treaty of Tilsit in 1807. Russia pledged to provide aid to Napoleon in his war against Britain; in turn, the Emperor of Russia would receive the Ottoman territories of Moldavia and Wallachia. If the Sultan refused to surrender these territories, France and Russia were to attack the Empire, and the Ottoman domains in Europe were to be partitioned between the two allies. The Napoleonic scheme threatened not only the Sultan, but also Britain, Austria and Prussia, which were almost powerless in the face of such a potent alliance. The alliance naturally proved accommodating to the Austrians, who hoped that a joint Franco-Russian attack, which would probably have utterly devastated the Ottoman Empire, could be prevented by diplomacy; but if diplomatic measures failed, the Austrian minister Klemens von Metternich decided that he would support the partition of the Ottoman Empire—a solution disadvantageous to Austria, but not as dangerous as a complete Russian takeover of Southeastern Europe. An attack on the Empire, however, did not come to pass, and the alliance concluded at Tilsit was dissolved by the French invasion of Russia in 1812. Following Napoleon's defeat by the Great Powers in 1815, representatives of the victors met at the Congress of Vienna, but failed to take any action relating to the territorial integrity of the decaying Ottoman Empire. This omission, together with the exclusion of the Sultan from the Holy Alliance, was interpreted by many as supportive of the position that the Eastern question was a Russian domestic issue that did not concern any other European nations. Serbian revolution The Serbian revolution or Revolutionary Serbia refers to the national and social revolution of the Serbian people between 1804 and 1815, during which Serbia managed to fully emancipate itself from the Ottoman Empire and exist as a sovereign European nation-state, and a latter period (1815–1833), marked by intense negotiations between Belgrade and the Ottoman Empire.
