Okay kiddo, let me explain to you what the Kingdom of Gwynedd is. Imagine a long, long time ago, there was a group of people who lived in an area called Wales. They spoke a different language and had their own way of living. These people were called the Welsh.
Now, within the Welsh people, there was a group of rulers who were in charge of a certain area called Gwynedd. This area was located in the northwest part of Wales. These rulers were called kings and queens, like in a fairy tale.
The Kingdom of Gwynedd was their land, and they were responsible for taking care of the people who lived there. They made sure everyone had food to eat, places to live, and were safe from harm. The kings and queens were very important to the people of Gwynedd.
They had their castle in the city of Bangor, and it was where they lived with their families. The castle was protected by high walls and large gates to keep the enemies out. The kings and queens had their knights to help them defend the castle.
The Kingdom of Gwynedd was also known for its special things, like its own language and customs. The Welsh people were proud of their rich traditions and their connection to their land. They had their own music, poetry, and stories that they passed down from generation to generation.
So, in short, the Kingdom of Gwynedd was a place where the Welsh kings and queens ruled over a certain part of Wales, and they were responsible for taking care of the people who lived there. They had their castle in Bangor, and the Welsh people were proud of their special language and customs.
