The Heads of the Proposals

The Heads of Proposals was a set of propositions intended to be a basis for a constitutional settlement after King Charles I was defeated in the First English Civil War. It was drafted in the summer of 1647 by Commissionary-General Henry Ireton and Major-General John Lambert.

In 1646 the Scots captured King Charles I and opened negotiations with Parliament. It demanded the Newcastle propositions that included accepting the covenant, installing a Presbyterian form of church government, giving Parliament control of the Army for 20 years, and turnover key supporters for punishment. Charles refused to accept these stiff terms.

The main propositions were:

Even after the occupation of London by the New Model Army had taken place, Parliament, instead of taking up the Heads of the Proposals as the basis of a settlement of the kingdom, sent to the King a revised edition of the Newcastle Propositions, differing mainly in that it proposed a limited toleration for dissentient Puritans, whilst forbidding all use of the book of Common Prayer. In his reply to their propositions, the King, on 14 September, expressed a preference for the Proposals of the Army, as more conducive "to the satisfaction of all interests and a fitter foundation for a lasting peace". Major Huntington's letter shows that the King expected the leaders of the Army to stand by him in procuring an offer of better terms from parliament.

The question of a new treaty was discussed in the House of Commons on 22 and 23 September 1647. Henry Marten and his party were eager for the passing of a vote to make no further addresses to the King. Cromwell and Ireton, on the other hand, opposed Marten's motion, and the House finally resolved on 23 September that they would once again make application to the King. This decision led to much discontent amongst the Levelling party in the Army as also outside of it, and "the credit and reputation" of both Cromwell and Ireton was much blasted thereby. They were accused of falsely representing it to be the desire and sense of the Army that this new application should be made to the King. The charge is thus stated by Wildman in his Putney Projects (p. 43).

Because Oliver Cromwell and Henry Ireton negotiated with the King, they lost the army radicals' support. The radicals criticized their "servility" to the king. Without an amicable solution between the Army, King, English Parliament, and the Scots the Second English Civil War started.
