Rue Saint-Nicaise, Plot of the

The plot of the Rue Saint-Nicaise, also known as the Machine infernale (English: Infernal machine) plot, is an assassination attempt on the life of the First Consul of France, Napoleon Bonaparte, in Paris on 24 December 1800.

It follows the conspiration des poignards of 10 October 1800, and is one of many Royalist and Catholic plots.The name of the Machine Infernale, the "infernal device", is in reference to an episode during the sixteenth-century revolt against Spanish rule in Flanders.

In 1585, during the Siege of Antwerp by the Spaniards, an Italian engineer in Spanish service had made an explosive device from a barrel bound with iron hoops, filled with gunpowder, flammable materials and bullets, and set off by a sawed-off shotgun triggered from a distance by a string.

The Italian engineer called it la macchina infernale.
