The first Oktoberfest was celebrated to commemorate Prince Ludwig’s marriage to Princess Therese of Sachsen-Hildburghausen. The celebrations started on October 12, 1810, and ended on October 17, 1810.
The festivities concluded with horse racing. Following a successful party, the couple decided to make it an annual event. The galas used to be held in October every year until the weather prompted them to be shifted to September.
