Okay kiddo, let me explain the timeline of Berlin in a very simple way. Berlin is a very old city in Germany, it has a long and interesting history that goes back thousands of years. Here's a timeline from when the city was founded until now:
1. In the 13th century, Berlin was just a small town called "Cölln" near a river named "Spree".
2. In 1237, a guy named "Albert the Bear" founded a new town nearby called "Berline".
3. In the 15th century, Berlin became the capital of the state of Brandenburg.
4. Over the next few centuries, Berlin became more important and bigger. It was the center of the Prussian Empire, a powerful kingdom in Europe.
5. In the 20th century, Berlin was affected by two World Wars. During World War II, the city was bombed heavily and many people died. The city was divided into East Berlin (communism) and West Berlin (democracy).
6. In 1961, the East German government built a wall to separate East and West Berlin to stop people from escaping from communist rule. The wall became a symbol of the Cold War.
7. In 1989, after decades of division and tension, the wall came down and East and West Berlin were reunited as one city.
8. In the 21st century, Berlin became a cosmopolitan city and the capital of reunified Germany. It's famous for its vibrant art and music scene, cultural diversity, and history.
That's the timeline of Berlin in a nutshell, I hope that makes sense to you, kiddo!
