On 23 February 1657, during a sitting of the Second Protectorate Parliament, Sir Christopher Packe, a Member of Parliament and former Lord Mayor of London (chosen by those supporting Kingship as he was a less controversial character than the leaders of the Kingship party), presented the Lord Protector Oliver Cromwell with a remonstrance which became known as the Humble Petition and Advice.
[4] They in themselves were an expression of strong latent support for monarchy and the English traditional constitutional limits on its power, a desire to lose the military overtones of the earlier Protectorate and the decreasing level of control Cromwell was able to exert due to ill health and frustration with a lack of revolutionary ideology amongst his subjects.
The intention of the Humble Petition and Advice was to offer a hereditary monarchy to Oliver Cromwell, to assert Parliament's control over new taxation, to provide an independent council to advise the king, to assure the holding of 'Triennial' meetings (every three years) of Parliament, and to reduce the size of the standing army in order to save money, amongst other things.
However, the real sticking point for many radicals were Clauses 10 through 12; these placed severe restrictions on sects like Fifth Monarchists and Baptists, while seeking to re-establish a national church structured along Presbyterian lines.
On 25 May, Cromwell ratified a modified Humble Petition and Advice and said that he would nominate his successor as Lord Protector.
