Napoleon I in the context of "Corps"

The Charter of 1815, signed on 22 April 1815, was the French constitution prepared by Benjamin Constant at the request of Napoleon I when he returned from exile on Elba. Officially named the Additional Act to the Constitutions of the Empire, the document extensively amended (in fact virtually replacing) the previous Napoleonic Constitutions (Constitution of the Year VIII, Constitution of the Year X and Constitution of the Year XII). The Additional Act reframed the Napoleonic constitution into something more along the lines of the Bourbon Restoration's Charter of 1814 of Louis XVIII, while otherwise ignoring the Bourbon charter's existence. It was very liberal in spirit, and gave the French people rights which had previously been unknown to them, such as the right to elect the mayor in communes of less than 5,000 in population. Napoleon treated it as a mere continuation of the previous constitutions, and it therefore took the form of an ordinary legislative act "additional to the constitutions of the Empire".

Napoleon III (born Charles-Louis Napoléon Bonaparte; 20 April 1808 – 9 January 1873) was President of France from 1848 to 1852 and then Emperor of the French from 1852 until his deposition in 1870. He was the first president, second emperor, and last monarch of France.

Napoleon III was born at the height of the First French Empire in the Tuileries Palace in Paris, the son of Louis Bonaparte, King of Holland (r. 1806–1810), and Hortense de Beauharnais, and paternal nephew of the reigning Emperor Napoleon I. It would only be two months following his birth that he, in accordance with Napoleon I's dynastic naming policy, would be bestowed the name of Charles-Louis Napoleon, however, shortly thereafter, Charles was removed from his name. Louis Napoleon Bonaparte was the first and only president of the French Second Republic, elected in 1848. He seized power by force in 1851 when he could not constitutionally be re-elected. He later proclaimed himself Emperor of the French and founded the Second Empire, reigning until the defeat of the French Army and his capture by Prussia and its allies at the Battle of Sedan in 1870.

The War of the Third Coalition (French: Guerre de la Troisième Coalition) was a European conflict lasting from 1805 to 1806 and was the first conflict of the Napoleonic Wars. During the war, France and its client states under Napoleon I and its ally Spain opposed an alliance, the Third Coalition, which was made up of the United Kingdom, the Austrian Empire, the Russian Empire, Naples, Sicily, and Sweden. Prussia remained neutral during the war.

Britain had already been at war with France following the breakdown of the Peace of Amiens and remained the only country still at war with France after the Treaty of Pressburg. From 1803 to 1805, Britain was under constant threat of a French invasion. The Royal Navy, however, assured its naval dominance at the Battle of Trafalgar in October 1805.

The Battle of Friedland (14 June 1807) was a major engagement of the Napoleonic Wars between the armies of the French Empire and the Russian Empire led by Napoleon I and General Levin August von Bennigsen respectively. Napoleon and the French obtained a decisive victory that routed much of the Russian army, which retreated chaotically over the Alle river by the end of the fighting. The battlefield is located in modern-day Kaliningrad Oblast, near the town of Pravdinsk, Russia.

The engagement at Friedland was a strategic necessity after the Battle of Eylau earlier in 1807 had failed to yield a decisive verdict for either side. The battle began when Bennigsen noticed the seemingly isolated reserve corps of Marshal Lannes at the town of Friedland. Bennigsen, who planned only to secure his march northward to Wehlau and never intended to risk an engagement against Napoleon's numerically-superior forces, thought he had a good chance of destroying these isolated French units before Napoleon could save them, and ordered his entire army over the Alle River. Lannes skillfully held his ground against determined Russian attacks until Napoleon could bring additional forces onto the field. Bennigsen could have recalled the Russian forces, numbering about 50,000–60,000 men on the opposite bank of the river, and retreated across the river before the arrival of Napoleon's entire army but, being in poor health, decided to stay at Friedland and took no measures to protect his exposed and exhausted army. By late afternoon, the French had amassed a force of 80,000 troops close to the battlefield. Relying on superior numbers and the vulnerability of the Russians with their backs to the river, Napoleon concluded that the moment had come and ordered a massive assault against the Russian left flank. The sustained French attack pushed back the Russian army and pressed them against the river behind. Unable to withstand the pressure, the Russians broke and started escaping across the Alle, where an unknown number of them died from drowning. The Russian army suffered horrific casualties at Friedland – losing over 40% of its soldiers on the battlefield.

The Battle of Smolensk was the first major battle of the French invasion of Russia. It took place on 16–18 August 1812 and involved about 45,000 men of the Grande Armée under Emperor Napoleon I against about 30,000 Russian troops under General Barclay de Tolly. Napoleon occupied Smolensk by driving out Prince Pyotr Bagration's Second Army. The French artillery bombardment burned the city to the ground. Of 2,250 buildings, 84% were destroyed with only 350 surviving intact. Of the city's 15,000 inhabitants, about 1,000 were left at the end of the battle inside the smoking ruins. With over 15,000 casualties, it was one of the bloodiest battles of the invasion.

The Territory of Missouri was an organized incorporated territory of the United States that existed from June 4, 1812, until August 10, 1821. In 1819, the Territory of Arkansas was created from a portion of its southern area. In 1821, a southeastern portion of the territory was admitted to the Union as the State of Missouri, and the rest became unorganized territory for several years.

The Left Bank of the Rhine (German: Linkes Rheinufer, French: Rive gauche du Rhin) was the region north of Lauterbourg that is now in western Germany and was conquered during the War of the First Coalition and annexed by the First French Republic.

After the French attempt to create a Cisrhenian Republic had foundered, the territories west of the Rhine were reorganised into several French Departments. After the allied victory over Napoleon I in 1814, the territories were temporarily administered by the Central Administrative Departement (Zentralverwaltungsdepartement). The Sarre province and the district of Landau in der Pfalz, which had been French before the Napoleonic Wars, became by the final act of the Congress of Vienna ceded to the members of the anti-Napoleonic coalition. The annexations done under the First Republic were undone. From those territories, the Bavarian Circle of the Rhine (Rheinkreis) and the Hessian province of Rhenish Hesse (Rheinhessen) were formed in 1816.

The École normale supérieure – PSL (French pronunciation: [ekɔl nɔʁmal sypeʁjœʁ]; also known as ENS, Normale sup', Ulm or ENS Paris) is a grande école in Paris, France. It is one of the constituent members of Paris Sciences et Lettres University (PSL). Due to its selectivity, historical role, and influence within French society, the ENS is generally considered the most prestigious of the grandes écoles, as well as one of the most prestigious higher education institutions in France. Its pupils are generally referred to as normaliens, while its alumni are sometimes referred to as archicubes.

The school was founded in 1794 during the French Revolution, to provide homogeneous training of high-school teachers in France, but it later closed. The school was subsequently reestablished by Napoleon I as pensionnat normal from 1808 to 1822, before being recreated in 1826 and taking the name École normale in 1830. When other institutes called écoles normales were created in 1845, the word supérieure (meaning upper) was added to form the current name. In 1936, the institution started providing university-level education.
