One of Hitler's uses of the Enabling Act was to dissolve all of the state parliaments (except Prussia's) and reconstitute them based on the results of the partly-free federal election held in March (with the exception of Communist seats). Prussia was excluded from this measure because it had held state elections at the same time, with a similar result (a Nazi plurality). With the Communists now banned and most Social Democrats either jailed or in exile (the SPD would be banned outright in June), the Nazis now had a majority in the Prussian parliament, which elected Hermann Göring as Minister-President.
