“Oktoberfest is a sixteen-day festival held each year in Munich, Bavaria, Germany during late September (and running to early October). It is one of the most famous events in the city and the world's largest fair, with some six million people attending every year…
 
…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).”
