War of the Oxen
The War of the Oxen (German: Der Ochsenkrieg) was a military conflict between the two German states of County Haag and Bavaria-Landshut which lasted between 1421 and 1422. It was an offshoot of the larger Bavarian War (1420–1422). In 1914 the German writer Ludwig Ganghofer wrote "The War of the Oxen", a novel using the war as a backdrop. The novel has subsequently been made into two films and a television series.
