The House of Wittelsbach (German: Haus Wittelsbach) is a German dynasty, with branches that have ruled over territories including Bavaria, the Palatinate, Holland and Zeeland, Sweden (with Denmark and Norway), Hungary (with Romania), Bohemia, the Electorate of Cologne and other prince-bishoprics, and Greece. Their ancestral lands of the Palatinate and Bavaria were Prince-electorates, and the family had three of its members elected emperors and kings of the Holy Roman Empire. They ruled over the Kingdom of Bavaria which was created in 1805 and continued to exist until 1918.

The House of Windsor, the reigning royal house of the British monarchy, are descendants of Sophia of Hanover, a Wittelsbach Princess of the Palatinate by birth and Electress of Hanover by marriage, who had inherited the succession rights of the House of Stuart and passed them on to the House of Hanover.

Kurt Eisner (German pronunciation: [kʊʁt ˈʔaɪsnɐ]; 14 May 1867 – 21 February 1919) was a German politician, revolutionary, journalist, and theatre critic. As a socialist journalist, he organized the Socialist Revolution that overthrew the Wittelsbach monarchy in Bavaria in November 1918, which led to his being described as "the symbol of the Bavarian revolution". He is used as an example of charismatic authority by Max Weber. Eisner subsequently proclaimed the People's State of Bavaria but was assassinated by far-right German nationalist Anton Graf von Arco auf Valley in Munich on 21 February 1919.
