Plot of the rue Saint-Nicaise

The Plot of the rue Saint-Nicaise was an attempt on the life of Napoleon Bonaparte by the surviving royalists of the 13 Vendemiaire rebellion of 1795 on 24 December 1800.

History
Napoleon Bonaparte declared himself First Consul of France in 1799, having been made famous for defeating a royalist army that outnumbered him 6-to-1 in the 1795 13 Vendemiaire rebellion. He was soon to become Emperor, but a plot against his life soon developed. The leader was a one-eyed Royalist who had lost his eye to cannon fire in the rebellion back in 1795, and he plotted to assassinate Napoleon as he headed to an opera. Snipers lined the Rue Saint-Nicaise and their goal was to either shoot Napoleon and kill him, or shoot at an improvised explosive device known as "The Infernal Machine". However, the Assassin Order caught them in the process on 24 December 1800, killing the snipers. The machine was blown up, causing a fire, but the Assassins found evidence leading to the royalist leader, and they assassinated him and his conspirators.
