Almost taking over Europe.
He flew over England
I believe you mean the exploits of Napoleon Bonaparte in 1806, when he conquered most of Germany.
Napoleon Bonaparte
Napoleon Bonaparte had a problem with Haiti due to the successful slave rebellion led by Toussaint Louverture that resulted in Haiti gaining independence from France. Bonaparte's failure to reassert control over the island following the rebellion had significant economic and strategic implications for France.
A military coup took over the lawful French Government and installed General Napoleon Bonaparte as the First Consul of France.
Toussaint Louverture was imprisoned by Napoleon Bonaparte due to his involvement in Haiti's fight for independence from France. Napoleon saw Louverture as a threat to French control over the region and had him arrested and sent to France where he died in captivity in 1803.
No , Napoleon Bonaparte gave the United States the Louisiana Territory for 3 cents an acre for various reasons
Robespierre was the head of the First Republic of France ( or better known as the Reign of Terror) he presided over the National Convention and led the Revolution that brought down the House of Bourbon. Napoleon Bonaparte seized control in 1804 as consulate of the First Republic.
At first he was just trying to help France during their "Depression" then he did sorta get out of control and pretty much tried to. So...yes, he did.
Militry Dictatorships all over Europe
Well you didn't state a period in history to work with, but probably the greatest victor was Napoleon Bonaparte. Took over most of Europe, but was defeated once in Russia.
