The Reichsrat or Imperial Council is the upper house of the German legislature, consisting of 4 representatives from each state within Germany.
Before the second World War, the Reichsrat membership was based on one's peerage and membership in the royalty. After the end of the second World War, the Volksverfassung introduced equal representation for all states, with a fixed 4 members per state. Currently, there are 38 states in Germany, meaning that there are 152 members in the Reichsrat. It is not required that one be a member of royalty to be part of the Reichsrat, only that one not hold another office in one's own state while serving in the Reichsrat.
