I am interested in the modern history of Bavaria, but I can't really find any information on the Bavaria party outside the wiki. I would like to know who the chairman was in 1961, please and thank you.
Joseph Panholzer became chairman of the BP on 1959-02-22 and was replaced in 1963 by Robert Wehgartner according to "Parteien-Handbuch: Die Parteien der Bundesrepublik Deutschland 1945–1980" by Richard Stöss.
