Okay kiddo, let me tell you about a very important event called the Glyndŵr Rising. It happened a very long time ago in the year 1400 in Wales, which is part of the United Kingdom.
In those olden days, there was a powerful ruler named King Henry IV who ruled over Wales and England. But there was a man named Owain Glyndŵr who wanted Wales to be independent and have its own ruler. He was very popular among the people of Wales and had a lot of supporters who also believed in his idea.
One day, Owain and his supporters started a rebellion against King Henry IV, and this was known as the Glyndŵr Rising. They wanted to fight for Wales and establish an independent Welsh state. Owain became the leader of this rebellion and many people followed him.
The Glyndŵr Rising was not an easy fight, and it lasted for over ten years. There were many battles and clashes between Owain's supporters and King Henry's army. Sometimes Owain and his supporters were winning, and sometimes they were losing, but they always kept fighting.
Despite all their efforts, Owain's rebellion was eventually crushed by King Henry's army, and he was forced to go into hiding. He was never captured and disappeared from history, but his rebellion had a lasting impact on Wales. It inspired future generations of Welsh people to fight for their country's independence and made Owain a national hero.
So, that's the story of the Glyndŵr Rising, a brave rebellion led by Owain Glyndŵr to gain independence for Wales.
