context: The first Oktoberfest was organized in the form of horse rides on October 17, 1810, to honor the wedding of Crown Prince Ludvig Bavaria and Therese von Sachsen-Hildburghausen. Previously, horse rides had been held on Marienplatz, but this time the city of Munich organized an event outside the city walls near Sendlinger Berg. King Maximilian I ordered the area to be named after Theresienwiese, his grandmother. In 1850, Ludwig I of Bavaria, now the King, erected a large bronze casting statue in the area, the largest of which was last cast in ancient Rome. [1]
