Surya Majapahit is a name for a big kingdom that existed a long, long time ago in Indonesia. This kingdom was ruled by powerful leaders called "kings" who had strong armies and lots of people who followed them. They had a really cool symbol that represented them, which was the sun with stripes around it. This symbol was called "Surya" which means "sun" in a language called "Sanskrit".
The people who lived in the kingdom of Surya Majapahit had many different jobs, just like we do today. Some people worked in fields to grow food, others made tools and weapons, and some were very talented artists who made beautiful pottery and carvings. They also had big buildings like palaces and temples that were built out of stone and brick.
As time went on, other kingdoms began to rise in power and the kingdom of Surya Majapahit slowly faded away, but we can still learn a lot from their history and culture. It's important to remember their stories so we can understand how the world has changed and evolved over time.
