ELI5: Explain Like I'm 5

Personal union

Have you ever played a game with your friend where you both control one character and work together to win? That's kind of like what a personal union is!

In real life, a personal union happens when one person becomes the ruler of two different countries. It's like they're playing two different characters - the ruler of both countries at the same time.

When this happens, the ruler makes decisions for both countries, but each country still keeps its own laws, traditions, and government. It's like each country still has its own special abilities in the game, but the ruler is controlling both of them.

This can sometimes happen when a king or queen gets married to someone who is also a ruler of another country, or if a king or queen dies without any children and a relative from another country becomes the new ruler.

It's important to remember that even though one person is ruling both countries, they still have to make decisions that are good for each country individually. It's like playing a game where you have to make choices that help both characters win, rather than just one.
