Vijayanagara was a very big and important kingdom that existed a very long time ago in a place called South India. Just like how you have kings and queens, Vijayanagara also had a king who ruled over the kingdom. The people who lived in this kingdom were very smart and good at many things like building big temples, writing books and making beautiful art.
The kingdom had many important things in it, like big buildings made of stones called forts, beautiful gardens where flowers grew, and big lakes with lots of fish in them. The king of Vijayanagara was very powerful and had a lot of soldiers who protected his kingdom from any bad people who wanted to hurt it.
Many people from different parts of the world came to visit Vijayanagara to see all the beautiful and interesting things in the kingdom. Even famous travelers like Marco Polo came all the way from countries far away to see the kingdom of Vijayanagara.
But one day, some bad people came and started fighting with the king and the soldiers of Vijayanagara. They wanted to take over the kingdom and rule it themselves. The king of Vijayanagara fought very hard to protect his kingdom but unfortunately, he lost the battle and the bad people took over.
Although Vijayanagara is not a kingdom anymore, people still talk and learn about it today because it was a very important and special place in history.
