It began with the Royal Wedding on 12 October 1810 of King Ludwig I and Princess Therese of Saxony-Hildburghausen. The original "Oktoberfest" occurred in Munich, on October 12, 1810: For the commemoration of their marriage, Crown Prince Ludwig (later King Ludwig I) and Princess Therese of Saxe-Hildburghausen (namesake of the Theresienwiese festival grounds) organized a great horse race (the marriage took place on October 12; the horse race on October 17 — therefore, there are different dates named as being the first Oktoberfest).
