The English Civil War, as it is usually known, should really be seen as a wider conflict, as there were few areas of the British Isles which were not in some way affected. The fighting extended beyond England to Scotland, Ireland and Wales.
From 1629 to 1640, King Charles I ruled without Parliament, denying its involvement in passing laws and authorising taxes. To raise money, Charles resorted to a number of unpopular measures, such as the notorious ‘ship money’ (a tax to maintain the Royal Navy). But without Parliament, the country had no outlet for the redress of grievances.
England was largely a Protestant country. There was widespread fear of Roman Catholicism, which was associated with oppression and with England’s traditional enemies, France and Spain.
Charles’s marriage to a Catholic, Princess Henrietta Maria of France, and his introduction of what were considered ‘popish’ practices into the English Church, aroused mistrust. The King’s foreign policy, which did little to assist Protestants abroad, was also viewed with suspicion.
In 1637, Charles attempted to impose religious changes in Scotland. This was met with immediate resistance. In 1639 and 1640, the King conducted two campaigns (known as the Bishops’ Wars) to enforce his authority. He was twice defeated by a Scottish army, which then occupied northern England.
Charles eventually agreed not to interfere in Scotland's religion and paid the Scots' war expenses. Faced also with the need to pay his English troops, Charles was in a desperate financial state. He was now forced to recall Parliament.
When Parliament met in 1640, Charles expected to be granted money and support against the Scots. Instead, Parliament embarked upon a programme of legislation to restrict the King’s powers and to eliminate the ‘popish’ practices from the Church. It also tried to gain control of England’s armed forces by means of a Militia Bill.
Opposition to Royal policy was almost unanimous in 1640. But by 1641, it had weakened. Suspicion of the Scots, alarm at the proposed extension of Parliament’s powers, and fear of radical Protestant sects all helped to promote support for the King.
However, Charles’s refusal to compromise alienated many moderates who might otherwise have trusted and supported him.
In October 1641, encouraged by the King’s weakness against the Scots, Catholics in Ireland rose in rebellion, massacring Protestants in Ulster. Exaggerated tales of atrocities intensified the political crisis in England.
Some suspected that Charles himself was behind the rising. They feared that he would use any army raised for Ireland to suppress opposition in England.
In January 1642, Charles was foiled in his attempt to arrest five Members of Parliament who led the opposition to his policies. He left London for York, and both sides prepared for war.

In the months that followed, armies loyal to the King and Parliament fought for control of key cities and strongholds all over the country.
Parliament soon established control of most of the east and south-east of England. Support for the King centred mostly in the west, north and Wales. Elsewhere, loyalties were divided. And it was in these disputed areas that most of the fighting occurred.
Parliament's victory at Naseby in June 1645 proved to be the decisive engagement. This 'First Civil War' ended with the surrender of the Royalist headquarters at Oxford in June 1646.

'The air was so darkened by the smoke of powder that for a quarter of an hour there was no light seen, but what the fire of the volleys of the shot gave, and ’twas the greatest storm I ever saw'.
Captain Richard Atkyns at the Battle of Lansdown, 1643
The coming of the Civil War in 1642 divided friends, families, and local communities. There was no such thing as a ‘typical’ Royalist or Parliamentarian. Soldiers on both sides fought for a variety of motives, and with varying degrees of enthusiasm. Religious conviction, mistrust of Royal power, local rivalry, economic discontent or loyalty to King, landlord, family or friends could all influence allegiances.
Self-interest also played its part. There was profit to be made from confiscated lands, while professional soldiers on both sides were suspected of wanting to prolong the fighting to keep themselves in employment.
Many of those who filled the ranks of both armies had little choice in the matter, often following the lead of their landlord or local gentry. If captured, they were often drafted into the opposing army.
Some saw the conflict as a way of achieving radical political, social and religious change. They included 'Levellers' and 'Diggers', many of whom served in the Parliamentarian armies. Radical soldiers’ views were expressed at the Putney Debates of 1647, a series of discussions about the future constitution of Britain.
Many of the ideas expressed by soldiers and others challenged the entire social and political establishment of 17th-century Britain.
‘For really I think that the poorest he that is in England hath a life to live, as the greatest he; and therefore... I think it clear, that every man that is to live under a Government ought first by his own consent to put himself under that Government; and I do think that the poorest man in England is not at all bound in a strict sense to that Government that he hath not had a voice to put himself under.’
Colonel Thomas Rainsborough at Putney, 1647
England had no standing army in 1642, yet both sides managed to raise and sustain large forces. The money and men they needed came from many different sources.
English and Scottish officers who had fought in Europe during the Thirty Years’ War (1618-48) provided valuable military experience. Both sides also employed foreign mercenaries.
England’s militia, based on the Trained Bands, was often reluctant to fight outside its own localities. Most other recruits came from the labouring classes, but many ‘gentleman volunteers’ also fought in the ranks, particularly in cavalry units.
‘I care not for your cause; I come to fight for your half-crown, and your handsome women.’
Croatian mercenary Captain Carlo Fantom, c1643
By the end of 1643, both sides were desperately short of soldiers and were forced to resort to local conscription. This did little to solve the problem as desertion was rife and local officials always tried to get rid of the worst men. Prisoners of war were also pressed into service.
Both sides were always short of money. They raised what they could by taxation, forced loans, gifts and outright plunder. The King also obtained supplies on credit in Europe.
As the war progressed, Parliament’s methods of raising money became very well-organised, allowing it to maintain first the army of the Eastern Association and later the New Model Army.
Formed in 1645 from the remains of three older Parliamentarian armies, the New Model Army was a radical departure from the past - a national fighting force not tied to a region or locality.
Full-time, disciplined, ideologically motivated, regularly paid and commanded by officers promoted on the basis of ability, not blood, it was the most important force in the country. It became the model for a future British standing army. Indeed, many of its soldiers continued to serve after 1660 in the army of the restored King Charles II.
The New Model Army eventually secured victory for Parliament in the war, winning the decisive Battle of Naseby (14 June 1645).
‘I had rather have a plain, russet-coated Captain, that knows what he fights for, and loves what he knows, than that which you call a Gentleman and is nothing else.’
Lieutenant-General Oliver Cromwell, 1645
The common belief is that Royalist ‘Cavaliers’ all wore large floppy hats with feathers, while Parliamentary ‘Roundheads’ wore what the Victorians called ‘lobster pot helmets’. This is a 19th-century myth. Both sides in the war would have looked similar and the quality of any item of dress would depend on the status of the wearer, not his allegiance.
Officers on both sides were members of the gentry. Most wore their own fine-quality civilian clothes under a buff coat and gorget. A sash worn over the left shoulder across the body, or around the waist, indicated an officer’s rank.
It was often difficult to distinguish friend from foe. To overcome this problem, both sides made use of field signs, such as a piece of white paper in the hat or passwords. But even so, mistakes were frequently made, sometimes with fatal consequences. Later on, the New Model Army wore distinctive red uniforms and its individual regiments were distinguished by the colours of their cuffs.
Known as the 'Foot', infantry were usually organised in regiments. About two-thirds of a regiment was armed with a matchlock musket, the rest with a sixteen-foot, steel-tipped pike. Muskets were wildly inaccurate, but lethal at close range. Pikemen were needed to protect the musketeers from cavalry - no horse would charge onto the closely-packed points of their pikes.
Called the 'Horse', cavalry were also formed into regiments, but sometimes operated in independent troops. Ideally a cavalry trooper would possess a sword, a pair of pistols, helmet, buff coat, back and breastplate, and a steel gauntlet to cover his bridle hand. In practice, few were so lavishly equipped.
Dragoons were mounted infantry, who dismounted to fight. They were armed with muskets and swords.
Artillery pieces were fairly clumsy and difficult to move. They varied in calibre and their rate of fire was slow. They were more useful for sieges than on the open battlefield.
Many soldiers were employed on garrison duty in towns, and saw little fighting. A large number never left their own counties. To those with the field armies, however, the war meant frequent marches, cold, hunger, tiredness and disease.
Most armies fluctuated in size during the conflict as a result of losses and desertion, but usually numbered in the thousands. At Edgehill (1642) both sides fielded about 14,000 soldiers. At Naseby (1645), the 9,000 Royalists were outnumbered by the 13,500-strong Parliamentarians.
The initial establishment of the New Model Army in 1645 was around 24,000 men. This was based upon infantry regiments 1,200 men strong, cavalry regiments of 600 troopers and a dragoon regiment of 1,000 soldiers. In practice, such unit strengths were rarely attained during the conflict.
'The enemy’s cannon...were somewhat dreadful when bowels and brains flew in our faces.'
Sergeant Henry Foster at the First Battle of Newbury, 1643
Although Charles’s forces had been beaten in the field, he still refused to reach a settlement, hoping to exploit the political divisions of his opponents. The King continued to negotiate in secret for support.
In 1648, there was a series of Royalist uprisings across England and Wales, and an invasion of northern England by the Scots. These were all defeated by Parliament's New Model Army.
The events of 1648 convinced Parliament that the King could never be trusted. In January 1649, he was brought to trial and found to have 'traitorously and maliciously levied war against the present Parliament and the people'.
Charles was executed outside the Banqueting House in Whitehall on 30 January. He is the only English monarch to have been executed for treason.
Soon after, Oliver Cromwell landed in Ireland to defeat the supporters of Charles's son and heir, the exiled Charles II. His bloody conquest completed the British colonisation of Ireland, which was merged into the newly-formed Commonwealth alongside England and Scotland.
The invasion destroyed the native Irish Catholic land-owning classes, replacing them with colonists with a British Protestant identity.

‘This is a righteous judgement of God upon these barbarous wretches, who have imbrued their hands in so much innocent blood and that it will tend to prevent the effusion of blood for the future, which are satisfactory grounds for such actions, which otherwise cannot but work remorse and regret.’
Lieutenant-General Oliver Cromwell after the Siege of Drogheda, 1649
In 1650, the exiled Charles II landed in Scotland and was crowned at Scone the following year. In a move designed to stop any possible Scottish invasion of England, Cromwell marched north in response.
At first out-manoeuvred by the Scots, Cromwell then destroyed a Scottish army at the Battle of Dunbar on 3 September 1650. Despite this, Charles himself then invaded England at the head of another army. This was defeated at Worcester on 3 September 1651 and Charles was forced back into exile.
In 1653, Cromwell used the New Model Army to disband Parliament, irritated by its self-serving interests and slowness in developing political solutions for the Commonwealth. In the process, he became Lord Protector, going on to rule England until his death in 1658.
But Cromwell could not agree with his new Protectorate Parliaments either. He dismissed them and, instead, ruled the country through his major-generals. England became a military dictatorship.
This military involvement in politics created a popular suspicion of standing armies that lasted well into the 19th century.

A recent estimate suggests that there were around 250,000 war-related deaths (military and civilian) in Britain during the conflicts - nearly 5 per cent of the population. This was a greater proportion than the 2.6 per cent of the population who died in the First World War (1914-18).
Deaths in Ireland probably numbered well over 250,000, possibly around 15-20 per cent of the estimated pre-war population.
The Civil Wars ensured that kings and queens would never again be supreme in British politics. Although the monarchy was restored in 1660 with the accession of Charles II, the later Stuart and Hanoverian kings had a very different, conditional relationship with their parliaments compared to some of their Continental cousins.
The possibility of absolute monarchy died with Charles I. Indeed, attempts by another of his sons, James II, to strengthen royal power - including using the army as an instrument of political control - led to his downfall in the 'Glorious Revolution' of 1688.
This finally secured the primacy of Parliament over the monarchy. It also gave Parliament control over the army, one of the issues that had helped cause the civil war.
