The Orsini bomb was a terrorist improvised explosive device built by and named after Felice Orsini and used as a hand grenade on 14 January 1858 in an unsuccessful attack on Napoleon the Third. The weapons were somewhat commonly used by anarchists in the latter half of the 19th century in Europe, and surplus bombs were also used by the Confederacy during the American Civil War. The design is reminiscent of modern impact fused grenades, such as the Soviet RGO hand grenades. Orsini bombs were designed to remove “the uncertainty of slow burning fused weapons".
