So, you know how there's this thing called football, right? Well, a long time ago, some people in Europe wanted to start playing football too. But they didn't really call it football, they called it American Football because it's the kind of football that's popular in America.
So, the NFL (which stands for National Football League) decided they wanted to help out and spread the love of American Football to Europe. They created something called NFL Europe which was like a league for football teams in Europe.
There were teams from a bunch of different countries like Germany, England, and Spain. They played games against each other and there was even a big championship game where the best teams got to compete to be the champions of NFL Europe.
It was pretty cool because it gave people in Europe a chance to watch and play American Football, even though it wasn't as popular there as it is in America. But after a while, the league decided to stop having games in Europe because it wasn't making as much money as they wanted it to.
But, some people still remember NFL Europe fondly and still love playing and watching American Football in Europe to this day.
