Okay, so Ramas are like the bosses of Thailand. They are kings who have a very important job of taking care of the whole country and making sure everyone is happy and safe.
There were many Ramas in Thailand, but we'll talk about the most popular ones.
The first Rama was like the very first boss of Thailand. He was called Rama I. Then after him, there was Rama II, Rama III, and so on. Each Rama had their own special job like building temples or protecting the country from enemies.
People in Thailand really love their Ramas because they do a lot of good things for them. And even though they're kings, they still try to help everyone out and make their lives better.
So that's what Ramas are: they're like big bosses who work hard to keep everyone happy in Thailand.
