The Reign of Terror (5 September 1793 – 28 July 1794), also known as The Terror , was a period of violence that occurred after the onset of the French Revolution, incited by conflict between two rival political factions, the Girondins and The Mountain, and marked by mass executions of "enemies of the revolution". The death toll ranged in the tens of thousands, with 16,594 executed by guillotine (2,639 in Paris), and another 25,000 in summary executions across France.

Reign of Terror is the second studio album by Australian metalcore band Capture The Crown. The album was produced by both Matt Good and Taylor Larson from the band From First to Last, and was released through the record label Artery Recordings. The first single off the album, "To Whom It May Concern", was released on 9 June 2014. It is the last album to feature guitarists Kris Sheehan, Jye Menzies, and drummer, Tyler March, after their departures on 4 October 2014, as well as the first album to feature bassist Maurice Morfaw. Reign of Terror was re-released as a deluxe edition with the five tracks from the "Live Life" EP on 24 November. Reign of Terror charted at No. 86 on the U.S. Billboard 200, the band's first album to chart in the U.S., as well as the third Australian metal band to chart.
