Oktoberfest 2009, Munich, Germany

In 1933, the Bavarian white and blue flag was replaced with the swastika flag. During World War II, from 1939 to 1945, no Oktoberfest took place. Following the war, from 1946 to 1948, Munich celebrated only the "Autumn Fest." The sale of proper Oktoberfest beer—2% stronger in alcohol than normal beer—was not permitted; guests could only drink normal beer.
• Modern festival
Since 1950, there has been a traditional festival opening: A twelve gun salute and the tapping of the first keg of Oktoberfest beer at 12:00 by the incumbent Mayor of Munich with the cry "O' zapft is!" ("It's tapped!" in the Austro-Bavarian language) opens the Oktoberfest. The Mayor then gives the first beer to the Minister-President of the State of Bavaria. The first mayor to tap the keg was Thomas Wimmer.
