4.4: The Beginning of the English Civil War

Charles I’s Religious Policies and Tensions with Parliament

Charles I sought to introduce more ceremony into the Church of England and revised the Prayer Book. When he tried to impose this new Prayer Book on the Presbyterian Church in Scotland, it caused serious unrest. A Scottish army was formed, and Charles could not finance his own army without Parliament’s help. In 1640, he was forced to reconvene Parliament to request funds.

At this time, many members of Parliament were Puritans, a strict group of Protestants who disagreed with the king’s religious policies and opposed his reforms of the Church of England. When Parliament refused to grant Charles the money he needed, even after a Scottish army invaded England, tensions escalated.

Rebellions in Ireland and the Power Struggle with Parliament

At the same time, a rebellion broke out in Ireland, where Roman Catholics feared the growing power of the Puritans. Parliament seized the opportunity to demand control over the English army, a move that would have significantly reduced the king’s authority. In response, Charles I entered the House of Commons and attempted to arrest five of its leaders, but they had been forewarned and were not present. Since this event, no monarch has set foot in the Commons.

With tensions at a breaking point, civil war between the king and Parliament became inevitable. In 1642, the country split into two factions: those who supported the king, known as the Cavaliers, and those who supported Parliament, called the Roundheads.

Oliver Cromwell and the English Republic

Oliver Cromwell was a key figure in British history, serving as Lord Protector of England, Scotland, and Ireland from 1653 to 1658 after leading parliamentary forces to victory in the English Civil War.

He played a significant role in the execution of King Charles I in 1649, marking the first and only time Britain became a republic. Cromwell’s rule is remembered for his strict Puritan policies and military campaigns in Ireland, which remain controversial.

The Defeat of the King’s Army

During the English Civil War, the king’s forces were decisively defeated at the Battles of Marston Moor and Naseby. By 1646, it was evident that Parliament had won. Charles I was captured by the parliamentary army, but he refused to negotiate with them. In 1649, Charles was executed, marking a significant turning point in British history.

The Commonwealth and Cromwell’s Role

After the king’s execution, England declared itself a republic, known as the Commonwealth, with no monarch. Initially, it was unclear how the country would be governed, and the army held much of the power. One of the army’s generals, Oliver Cromwell, was sent to Ireland, where a rebellion that began in 1641 and a Royalist army still posed a threat. Cromwell reasserted the authority of the English Parliament in Ireland, but his brutal methods have left him a controversial figure there to this day.

Defeating Charles II and Securing Control

The Scots did not agree with the execution of Charles I and declared his son, Charles II, as king. Charles II was crowned king of Scotland and led a Scottish army into England. However, Cromwell defeated this army at the Battles of Dunbar and Worcester. Charles II narrowly escaped capture and fled to Europe, famously hiding in an oak tree during his escape. With his victory, Cromwell and Parliament now controlled Scotland in addition to England and Wales.

Cromwell as Lord Protector

After his military victories in Ireland and Worcester, Cromwell emerged as the leader of the new republic. In 1653, he was given the title of Lord Protector, ruling England, Scotland, and Ireland until his death in 1658. Upon Cromwell’s death, his son Richard succeeded him as Lord Protector but was unable to maintain control of the army or the government. Although Britain had been a republic for 11 years, the absence of a strong leader led to growing instability. Many began to call for the restoration of the monarchy.
