After he lost, why did the European powers send him to exile on an island, rather than trying and executing him? If the French revolutionaries could execute their king, why couldn't the victorious powers execute the emperor?
Because he was Freemason and the French Revolutionaries were started by French freemasons.
If he were to die defending france, he'd become a martyr and controlling the french people would become much more difficult. Also he powers in europe at that time were fags. They were afraid of killing a king/ leader of state because they thoughy it could happen to them tooI think napoleon's personal life and political work hasn't had much ideological influence on the modern society apart from providing navel gazing fodder for people who live in fringes of society
