How did world's biggest beer festival Oktoberfest originate?
Bavarian Crown Prince Louis married Princess Therese von Sachsen-Hildburghausen on October 12, 1810, and the royalty invited Munich's public to attend the celebrations. The festivities were repeated in the following years, giving rise to the annual tradition of Oktoberfest. Nearly 2 million gallons of beer are consumed during the festival, which presently begins in late September.
