The Treaty of London between England and Scotland, ending the Bishops’ Wars, is signed.

The **Bishops’ Wars** were a pair of conflicts fought between **Scotland and the forces of King Charles I of England in 1639 and 1640**. Their origins lay mainly in disputes over religion and royal authority. Charles I, who ruled both England and Scotland, attempted to impose changes on the Scottish Church, including a new prayer book introduced in 1637. Many Scots believed these reforms threatened their Presbyterian system and represented an attempt to make their church more like the Church of England. Opposition led to the signing of the **National Covenant in 1638**, whose supporters, known as Covenanters, pledged to defend the independence and religious practices of the Scottish Church.

The **First Bishops’ War** began in 1639 when Charles raised an army to confront the Covenanters. However, the king lacked sufficient money, experienced troops, and political support for a prolonged campaign. The Scottish Covenanters, meanwhile, had organized an effective military force that included veterans of the Thirty Years’ War. Little serious fighting occurred, and the conflict ended with the **Pacification of Berwick** in June 1639. The settlement failed to resolve the underlying dispute, however, and the **Second Bishops’ War** broke out in 1640. This time the Scots invaded northern England, defeating royal forces at the **Battle of Newburn** near Newcastle in August. Charles was forced to negotiate, and under the **Treaty of Ripon**, the Scottish army temporarily occupied parts of northern England while the king agreed to pay its expenses.

The Bishops’ Wars had consequences far beyond the dispute over Scottish religion. Charles desperately needed money to continue the struggle, forcing him to summon the English Parliament after ruling without it for eleven years. The **Short Parliament** of April 1640 refused to provide funds without first addressing grievances against the king and was quickly dissolved. Following his defeat by the Scots, Charles had little choice but to summon the **Long Parliament** in November 1640. The resulting confrontation between the monarchy and Parliament grew increasingly bitter and eventually contributed to the outbreak of the **English Civil War in 1642**. The Bishops’ Wars are therefore regarded as an important opening stage of the wider **Wars of the Three Kingdoms**, which engulfed England, Scotland and Ireland during the 1640s.
