Hey there kiddo, do you know what a kingdom is? It's like when a really powerful person, called a king or queen, has a big group of people who live in their land and follow their rules.
Now, a long time ago in a place called the Philippines, there was a king named Sri Lumay who came from Borneo. He sailed across the sea with his family and followers until he reached an island called Cebu.
When he arrived, he created a community and became the first ruler of what's called "Rajahnate of Cebu". A "rajahnate" is like a kingdom, but instead of a king or queen, they use the word "Rajah" (pronounced Ra-hah) which means ruler.
Under Sri Lumay's rule, the people of Cebu built a lot of things like houses, boats, and temples. They also traded goods with other kingdoms nearby.
After Sri Lumay passed away, his son Tupas became the new ruler. He improved the Cebuano's farming methods, built more structures, and strengthened the kingdom's army for protection against invaders.
Rajahnate of Cebu continued to be an important center of trade and culture until it was later conquered by the Spanish in the 16th century.
So in summary, the Rajahnate of Cebu was a kingdom ruled by a powerful leader called a "rajah" who helped the people build things and trade with others. It was an important place in history, but it doesn't exist anymore because it was conquered by the Spanish a long time ago.
