Napoleon was exiled because after his defeat and abdication, the victorious Coalition powers wanted to remove him from power without executing him, as executing monarchs and rulers was politically sensitive and could create a martyr. Initially, after his first abdication in 1814, Napoleon was exiled to Elba, a small Mediterranean island where he was allowed to rule but with restricted power. However, he escaped from Elba and returned to power for a brief period known as the Hundred Days before being defeated again at the Battle of Waterloo in 1815. Following this second defeat, the British and Coalition powers decided on a more secure exile to prevent any further return or uprising. Napoleon was exiled to the remote island of Saint Helena in the South Atlantic Ocean, far from Europe, under strict surveillance to ensure he would not escape again. This exile was intended to prevent him from disturbing the peace in Europe, as killing him could have had political repercussions by creating a martyr or undermining the idea of monarchical divine right. In summary, Napoleon’s exile was a strategic choice to neutralize his political and military threat without causing the political instability that might come from executing a ruler who had held the French throne. He spent his final years on Saint Helena until his death in 1821.
