The world's largest fair has a royal background
The festival originated in Theresienwiese (also known as Wies'n) in the 1800s when Crown Prince Ludwig, later to become King Ludwig I, was married to Princess Therese of Saxony-Hildburghausen on October 12, 1810. The citizens of Munich were invited to attend the festivities on the fields in front of the city gates.
Horse races that were first held at the wedding celebrations became so popular among the people that they decided to repeat them every year. This gave rise to the tradition of Oktoberfest.
An added feature to the horse races was the first agricultural show, designed to boost Bavarian agriculture. show.Visitors at this show were able to quench their thirst at small beer stands which grew rapidly in number. In 1896 the stands were replaced with tents and halls set up by enterprising landlords with the backing of breweries. There are currently 14 main tents at the Oktoberfest.
