To read someone the riot act means to sternly tell them to behave well, to demand good behavior and warn them of dire consequences if they do not stop what they are doing. The term read the riot act has its origins in an actual law called the Riot Act which was enacted in Britain in 1714. According to the law, if a crowd of twelve or more people showed signs of becoming unruly, the local authority would ask them to disperse. If they refused, the authority would read the Riot Act out loud, giving the group one hour to disperse. In sixty minutes, the authority would have the right to arrest anyone still around. Punishment was death. During the eighteenth and nineteenth centuries, the Riot Act was invoked often, and authorities were not obligated to wait sixty minutes after reading the Riot Act if circumstances began to spiral out of control. The first figurative use of read the riot act occurs in 1819. Related terms are reads the riot act, read the riot act and reading the riot act.
