Short answers, pulled from the story.
Napoleon Bonaparte's legacy is deeply contested. Historians describe him as both an enlightened reformer who spread modern legal codes across Europe and someone whose seventeen years of wars killed perhaps six million people, ending in France's total military defeat by the Treaty of Paris in 1815.
Napoleon lost the Peninsular War, the French invasion of Russia, the War of the Sixth Coalition, and the War of the Seventh Coalition. His total military defeat was confirmed by the Treaty of Paris in 1815.
The Napoleonic Code was retained by the Netherlands, Belgium, and parts of Italy and Germany after Napoleon's fall. It also became the legal foundation in the Dominican Republic, the American state of Louisiana, and the Canadian province of Quebec, and served as a model across much of Latin America.
Napoleon commissioned paintings directly to shape his public image. He instructed Jacques-Louis David to portray him "calm upon a fiery steed" crossing the Alps, and commissioned Antoine-Jean Gros to paint Bonaparte Visiting the Plague Victims of Jaffa in 1804 to counter reports of atrocities during the Egyptian campaign of 1798-1800. After the proclamation of the Empire in 1804, David became the regime's official court painter.
Napoleon is remembered warmly in Poland as a champion of independence. He created the Duchy of Warsaw after defeating Prussia and declared Polish independence a personal goal. Polish generals Jozef Poniatowski and Jan Henryk Dabrowski fought alongside him, and Napoleon is mentioned in the second stanza of the Polish national anthem "Poland Is Not Yet Lost."
Napoleon's invasion of Spain in 1808 forced the abdication of King Charles IV and his son Ferdinand VII, creating a power vacuum in Spain's American colonies. Native-born leaders including Simon Bolivar and Jose de San Martin filled that vacuum, ultimately winning independence across Latin America.
