Have you ever heard the word "metropolis"? It's a big city that has a lot of people and is very important in its country or region. Well, "metropole" is kind of like that, but it's not just a city - it's an entire area that controls and governs smaller areas around it.
Think of it like a big house with lots of rooms. The metropole is like the biggest and most important room in the house, and all the smaller rooms around it are controlled by the metropole. These smaller rooms might be cities, towns, or even whole countries.
In the olden days, when countries were expanding and trying to get more power and land, they would often set up a metropole in a new area they had conquered. The metropole would have a lot of influence and power over the smaller areas around it, and would make big decisions for them.
Nowadays, metropoles aren't just about power and control - they're also about working together and sharing resources. For example, in Europe, there's something called the "European Metropolis of Lille". This metropole is made up of 90 smaller towns and cities, all working together to improve transportation, the economy, and the environment.
So, to sum it up, a metropole is like a big boss that controls and governs smaller areas around it. But it's not just about power - it can also be about working together and sharing resources.
