Napoleon Bonaparte – Early Life

Napoleon Bonaparte was born on the French island of Corsica, on August 15th, 1769 as Napoleone di Buonaparte, but he changed his name to Napoleon Bonaparte during his 20s. His father, Carlo Buonaparte of Ajaccio, Corsica was an 18-year-old student when he married Maria-Letizia Ramolino, a 14-year-old girl also from Ajaccio. Both Carlo and Maria were descendants of minor Italian nobility and their ancestors were Italian mercenaries in Genoa Bay who settled in Corsica at the beginning of the 16th century. It is assumed that the Buonapartes were originally from Tuscany.

Napoleon did not receive any formal education until he was nine when he attended school and managed to obtain a place at the military college at Brienne thanks to his protector Comte de Marbeuf who was the governor of Corsica, and a family friend of Bonaparte’s.

Corsica
proper noun
Corsica is a French island in the Mediterranean Sea that the Genoese republic transferred to France through the Treaty of Versailles on May 15th, 1768, roughly fourteen months before Napoleon Bonaparte was born there. The island had its own distinct Italian-speaking culture and a long history under Genoese control before it became French territory.

Napoleon’s troops captured extensive territory in Italy, and he called on the Italian people to recognize him as their new leader. In May 1796, he forced Sardinia to sign a peace treaty, then turned to the war against the Austrians. He managed to beat the Austrians at Rivoli which led to the truce and the Treaty of Campo Formio in 1797. The Italian campaign and military success over the Italian and Austrian armies provided Napoleon a great reputation among his fellow soldiers and the people of France.

Also in 1796, Napoleon, who was 26 years old at the time, married Josephine de Beauharnais, a 32-year-old widow with two teenage children of her own.  The marriage lasted until 1809 when he divorced her because she had not produced any children for him to have an heir.

Next, he led a series of battles against Egypt which was an Ottoman province at the time.  He won several battles in Egypt, but British admiral Horatio Nelson destroyed his fleet at the Battle of the Nile.  Despite the loss of the fleet, he returned to France a national hero.

Napoleon Bonaparte – Napoleonic Wars

Immediately after coming to power, Napoleon launched a military campaign against members of the Second CoalitionAn alliance of several countries joined together to fight a common enemy. (Austria, Great Britain, Naples, the Ottoman Empire, Portugal, and Russia). Napoleon destroyed the Austrians at Marengo in 1800. The Austrians suffered a huge loss in soldiers and were forced out of Italy.  As a result, the Treaty of Lunéville was signed in 1801, which set the Rhine River as France’s new eastern border.  As well, the victory strengthened Napoleon’s stance in France politically and with the people of the country. He became the Emperor of France in 1804 and in 1805 he declared himself the king of Italy.

For the next decade, Napoleon undertook several major conflicts known today as the Napoleonic Wars.  These conflicts saw France face off against several European powers as Napoleon sought to expand France’s territory in the continent.  As well, he introduced many significant reforms into French society as he stabilized the country following the excesses of the French Revolution.  For example, he introduced the Napoleonic Code in 1804 which was a civil code of laws.  The Napoleonic Code reformed the country’s laws and introduced the idea of rule of law.

French forces moved eastward into Austria and in 1805, Napoleon encircled the Austrian army and forced General Karl Mack to surrender. He occupied Vienna, and at Austerlitz in 1805 he won a great victory over Austrian and Russian soldiers, which many historians consider to be Napoleon’s greatest military achievement. Austria was forced to sign the Treaty of Pressburg and leave the Third Coalition.  Next, Napoleon’s forces marched into Berlin and he won another victory at Friedland in 1807 against Russia. By the Treaties of Tilsit in 1807 half of Prussia’s territory was given to France and Napoleon had power over a major part of continental Europe.

In 1810, after divorcing his first wife Josephine, Napoleon married Marie Louise, the 19-year-old Archduchess of Austria.  The couple had one child, Napoleon Francis Joseph Charles, who was born in 1811.  At his birth, Napoleon gave him the title of the King of Rome.

Napoleon BonaparteQ&A
Facts that CrunchFactsthatCrunch
Q

How did French-controlled territory in Europe change across Napoleon's major battles from 1800 to 1815?

A

French victories at Marengo in 1800, Austerlitz in 1805, and Friedland in 1807 steadily expanded French-controlled territory across continental Europe, and the Treaties of Tilsit in 1807 cost Prussia roughly half of its territory. The failed Russian campaign of 1812 reversed that growth, as French forces could not hold Moscow and were forced to retreat with enormous losses. Defeats at Leipzig in 1813 and Waterloo in 1815 ended French territorial expansion entirely, returning France's borders close to where they had been before the Napoleonic Wars.

Napoleon Bonaparte – Decline and Death

The first signs of Napoleon’s decline began in the Peninsular War (1808–1814).  This war saw British forces team up with both Spanish and Portuguese forces to push France off of the Iberian Peninsula.  This was a major loss for Napoleon and was made worse by the catastrophic loss he was also experiencing in Russia.

Napoleon’s army was 500,000 men strong when he invaded Russia in 1812. French troops moved quickly into Russia, forcing Russian General Mikhail Kutuzov to rapidly withdraw deep into the country. At Borodino, a small village west of Moscow, a battle was held with great losses on both sides. Kutuzov withdrew further, and Napoleon entered Moscow on September 14th, 1812.  To the shock of the French, the city was nearly abandoned and had been burned by the Russians.  Russian citizens burned the city in order to not allow Napoleon’s troops to resupply.  The lack of supplies and freezing cold of the Russian winter eventually forced Napoleon to order his forces to retreat.  As they did, the Russian forces repeatedly attacked the French troops and by the time Napoleon and his army left Russia he had less than 100,000 soldiers remaining.  This was a major loss that Napoleon would be unable to recover from.

After his forces retreated from Russia, the Sixth Coalition against France was made. At the Battle of Leipzig, the Sixth Coalition won, and French troops were forced to return to France. Napoleon refused peace, and Coalition troops marched into Paris on March 31st, 1814. Napoleon abdicatedFormally gave up power as a ruler or emperor. on April 11th, 1814 and went into exileForced removal of a person to a distant place, away from their home country, as punishment. on the island of Elba off the coast of Italy. While the Congress of Vienna was establishing the borders of Europe, Napoleon escaped from Elba, landed at Cannes, and proceeded to Paris. He entered the city on March 20th, 1815 and thus began a period of rule known as “The Hundred Days” which saw him try to regain his position in France. Once again European armies were sent against Napoleon and he was famously defeated at the Battle of Waterloo. This time he was banished to the island of Saint Helena, a British controlled island in the south of the Atlantic Ocean.  He died there on May 5th in 1821.  His remains were eventually brought to France in 1840 where they remain today.

Napoleon Bonaparte – Significance

Napoleon Bonaparte was one of the most significant leaders in the 19th century and certainly one of the most influential leaders in history. For example, he had a profound impact on France and Europe during and after the French Revolution. More specifically, he preserved and expanded many revolutionary ideals, such as legal equality and secular education, through the Napoleonic Code. As a military leader, he reshaped the map of Europe and spread French nationalist ideals. Napoleon centralized power in France, strengthening the state while ending the violence and stagnation that was common in the French Revolution. Though his imperial ambitions led to widespread war and suffering, his reforms also modernized European governments and institutions. Historians continue to study his life and significance still to this day, with many focusing on his consolidation of power and establishment of the Napoleonic Code.
