ELI5: Explain Like I'm 5

Second Czechoslovak Republic

Many, many years ago, there was a place called Czechoslovakia. It was a country where lots of people lived together and had their own way of doing things, but they all agreed to be part of the same country.

But one day, some people who were in charge of the country decided they didn't want to be part of it anymore. They thought it would be better if they had their own country all to themselves. So they split Czechoslovakia into two parts: one part called the Czech Republic and another part called Slovakia.

But after some time had passed, people started to realize that maybe it wasn't such a good idea after all. They missed being part of the same big country and wanted to join back together again. So they did, and it became called the Second Czechoslovak Republic.

It was like when you split apart all your toys to play with them separately, but then you realize it's more fun when you combine all the toys together and play together as one big group!
