He hoped by doing so to obtain funding that would enable him to reverse his defeat by Scots Covenanters in the Bishops' Wars, but in return Parliament demanded a greater share in government than he was willing to concede.
Royalists generally argued both Parliament and the Church of England were subordinate to the king, while most of their Parliamentarian opponents claimed his supremacy did not extend to religion, and wanted a form of constitutional monarchy.
After the Grand Remonstrance was submitted in late 1641, moderates like Edward Hyde created a Royalist political faction, arguing Parliament was trying to alter the balance too much the other way.
Examples included his annulment of the 1628 Petition of Right, and the recent Bishops Wars, when he agreed peace terms with the Scots in 1639 only to provide time to plan another military campaign in 1640.
[16] While Puritans were the most visible in opposing Laudian reforms and demanding the removal of bishops from the Church of England, their objections were shared by many Royalists, such as George Morley and Sir Edmund Verney.
[d][17] One reason was that bishops held a variety of non-religious roles which impacted all levels of society; they acted as state censors, who were able to ban sermons and writings, while ordinary people could be tried by church courts for crimes including blasphemy, heresy, fornication and other 'sins of the flesh', as well as matrimonial or inheritance disputes.
[19] Their removal temporarily ended censorship, and especially in London led to an explosion in the printing of pamphlets, books and sermons, many advocating radical religious and political ideas.
As the war progressed, both they and their Scottish Covenanter allies came to see the Independents and New Model Army as more dangerous than the Royalists and formed the "Peace Party", seeking a negotiated end to the fighting.
[21] Lastly, in 1642 England and Wales were part of a highly structured, socially conservative and peaceful society, while the devastation caused by the Thirty Years War in Europe meant many wanted to avoid conflict at any cost.
Most of the Royal Navy declared for Parliament, allowing them to protect the trade routes vital to the London merchant community, block Royalist imports and resupply isolated Parliamentarian garrisons.
[28] On 1 June 1642, Parliament approved a list of proposals known as the Nineteen Propositions, which would give them control over ministerial appointments, the army and management of the Royal household, including the education and marriage of his children.
Elsewhere, Sir William Waller secured the south-east for Parliament; in December, Lord Wilmot captured Marlborough, opening communications between Oxford, and Royalist forces based at Launceston, in Cornwall.
With insufficient troops to hold the entire area, his task was further complicated by Parliamentarian forces under Lord Fairfax and his son Thomas, which retained key towns like Hull and Leeds.
Along with Henrietta Maria, the weapons convoy finally managed to land at Bridlington in late February; on 4 June she left York escorted by 5,000 cavalry, arriving in Oxford in mid-July.
[44] Although Hopton reached Winchester, Waller prevented him making further progress; in October, Newcastle abandoned the second siege of Hull, while victory at Winceby secured eastern England for Parliament.
[47] The Solemn League created a Committee of Both Kingdoms to co-ordinate strategy in all three war zones, England, Scotland and Ireland, although Pym's death in December 1643 deprived Parliament of their most important leader.
To avoid being shut up in Oxford, a field army nominally commanded by Charles retreated to Worcester; Essex ordered Waller to remain there, while he went west to relieve the siege of Lyme Regis.
[55] Failure to exploit Marston Moor, Essex' capitulation at Lostwithiel, and Manchester's alleged unwillingness to fight at Newbury led to claims some senior commanders were not committed to victory.
[60] Lord Goring's Western Army made another attempt on Portsmouth and Farnham; although he was forced to retreat, it showed Parliament could not assume this area was secure, while Montrose's Highland Campaign opened another front in the war.
[61] On 31 May, Prince Rupert stormed Leicester; in response, Fairfax and the New Model Army abandoned their blockade of Oxford, and on 14 June, won a decisive victory at Naseby.
In July, Fairfax lifted the siege of Taunton; a few days later at Langport, he destroyed Lord Goring's Western Army, the last significant Royalist field force.
[66] At the end of August, Charles left Oxford to relieve Hereford, which was besieged by the Covenanter army; as he approached, Leven was ordered to return to Scotland, following Montrose's victory at Kilsyth.
The loss of Carmarthen and Chepstow in South Wales cut connections with Royalist supporters in Ireland (see Map) and Charles made his way back to Oxford, where he spent the winter besieged by the New Model.
[69] Following the fall of Hereford in December 1645, the Royalists held only Devon, Cornwall, North Wales, and isolated garrisons in Exeter, Oxford, Newark, and Scarborough Castle.
When Prince Rupert told him in August 1645 that the war could no longer be won, Charles responded that while this may have been an accurate assessment of the military situation, 'God will not suffer rebels and traitors to prosper'.
[76] The result was the creation of a powerful faction who believed Charles would never voluntarily agree to a suitable political settlement, and whose control of the New Model Army gave them the ability to impose one.
Often grouped together as 'Independents', the reality was far more fluid; Sir Thomas Fairfax was a Presbyterian, who fought for Charles in 1639, and refused to participate in his execution, while even Cromwell initially viewed him with great respect.
[77] William Fiennes, 1st Viscount Saye and Sele, and his sons Nathaniel and John, are examples of those supported the Independents out of religious conviction, but wanted Charles to retain his throne.
By March 1647, these arrears amounted to some £2.5 million, an enormous sum for the period, and moderates in Parliament led by Denzil Holles decided to remove the threat by sending the army to Ireland.
[79] Importantly, only those who agreed to go would receive their arrears, and when regimental representatives, or Agitators, demanded full payment for all in advance, Parliament disbanded the New Model, which refused to be dissolved.
