Henry III, in 1258, at the desire of the Great Council in Parliament, consented to the appointment of a committee of twenty-four, of whom twelve were appointed by the Barons and twelve by the King, in a parliament which was stigmatized as the “Mad Parliament.” Unlimited power was given to it to carry out all necessary reforms. It drew up the Provisions of Oxford.
