Berlin began as a small trading center in the 13th century on the banks of the Spree River. It became the capital of Prussia in 1701 and transformed into a significant cultural and political center under the Hohenzollern dynasty. Berlin underwent rapid industrialization in the 19th century, becoming a major European city and hub for science and culture. The city played a pivotal role in both World Wars and was severely damaged in World War II. After the war, Berlin was divided during the Cold War until reunification with the fall of the Berlin Wall in 1989. Today, Berlin is known as a global city with a vibrant culture and art scene that attracts many visitors to experience its dynamic history.
