The Oktoberfest in Munich is the largest folk festival in the world. For two weeks each year, more than 6 million people invade the Bavarian capital and push the city to its limits, drinking close to 7 million liters of beer in the process. The festival, or "Wiesn" (meadow) as the locals call it, started as a horse race to celebrate the wedding of Bavaria's Crown Prince Ludwig and princess Therese in October 1810. The event was so popular that the king decided to hold it annually, and it soon became famous beyond the borders of Bavaria. Attracting locals as well as people from all over the world, the Oktoberfest today has become a unique blend of traditional Bavarian culture and pop culture.
