Following the Peterloo Massacre on 16 August 1819, the government of the United Kingdom under Lord Liverpool acted to prevent any future disturbances by the introduction of new legislation, the so-called Six Acts aimed at suppressing any meetings for the purpose of radical reform. Élie Halévy considered them a panic-stricken extension of "the counter-revolutionary terror ... under the direct patronage of Lord Sidmouth and his colleagues";[1] some later historians have treated them as relatively mild gestures towards law and order, only tentatively enforced.[2]
