The Riot Act (1716)
“Our Sovereign Lord the King chargeth and commandeth all persons being assembled immediately to disperse themselves, and peaceably to depart to their habitations or to their lawful business, upon the pains contained in the act made in the first year of King George for preserving tumultuous and riotous assemblies. God save the King.
