German Unity Day is a public holiday celebrated annually on October 3rd in Germany. It commemorates the reunification of Germany in 1990 when the German Democratic Republic (East Germany) joined the Federal Republic of Germany (West Germany), creating a single German state for the first time since 1945. The fall of the Berlin Wall on November 9th, 1989, which marked the end of the Cold War, paved the way for German reunification barely a year later. The Unification Treaty that was signed on September 20th, 1990, and declared October 3rd as the national holiday, sealed the end of the division of Germany. The Day of German Unity is celebrated with festivals, exhibitions, and other activities around the country, with the main celebration taking place in a different city each year. The celebrations include live music, food, drinks, and sweets, and various artists present their art at the festival.
