A guillotine is an apparatus designed for effectively carrying out executions by beheading. The device consists of a tall, upright frame with a weighted and angled blade suspended at the top. The condemned person is secured with a pillory at the bottom of the frame, holding the position of the neck directly below the blade. The blade is then released, swiftly and forcefully decapitating the victim with a single, clean pass; the head falls into a basket or other receptacle below.

The Reign of Terror was a period of the French Revolution when, following the creation of the First Republic, a series of massacres and numerous public executions took place in response to revolutionary fervour, anticlerical sentiment, and accusations of treason by the Committee of Public Safety. While terror was never formally instituted as a legal policy by the Convention, it was more often employed as a concept.
