List of Prince-Electors of Electorate of Brandenburg (The Kalmar Union)

Brandenburg divided between the sons of Albert II; John I and Otto III.

George I is executed by a radical Republican Diet as it descends into chaos during the Brandenburg Civil War (1653-1659). The 'Commonwealth' would last until it was broken up by the Danish army in 1664.

Wolfgang Casimir's reactionary regime falls as passions are inflamed by Henry X of Luxembourg retaking Bohemia and his subsequent liberal regime there.
