First English Civil War, 1645

Long ago in England there was a big fight called the First English Civil War. It happened in the year 1645. Imagine you and your friends playing a game of tag. Sometimes in this game, one person becomes upset because they never get a turn to be "it." That's what happened in England. Some people were upset with the king because they didn't think he was sharing power fairly.

The king's name was Charles I, and he believed in something called the "Divine Right of Kings." This meant that he thought God had chosen him to be king and that he should have all the power. But some other people, called the Parliament, did not agree with him. They thought they should have a say in how the country was run. This made Charles I and the Parliament very angry with each other.

Things only got worse when Charles I tried to raise taxes without getting permission from the Parliament. This was against the law, and the Parliament said he couldn't do it. But Charles I didn't listen, and soon both sides were arguing and fighting over who had the power to make the laws.

The fighting started in 1642 when Charles I, with his army of soldiers called Cavaliers, went to war against the Parliament, who had their own soldiers called Roundheads. Led by a man named Oliver Cromwell, the Roundheads were able to defeat the Cavaliers in many battles.

In 1645, the Roundheads won a decisive victory at a place called Naseby. This meant that they were one step closer to winning the war. Eventually, after many more battles and negotiations, the Parliament won the war and Charles I was put on trial for treason. He was found guilty and was executed in 1649, which was a very sad ending to a long and bitter fight for power.
