Each voter had one vote, which was cast on an electoral district ballot. The number of seats was determined by
proportional representation. The number of Reichstag seats fluctuated because they depended on the total number of votes cast, with one seat allocated for 60,000 votes. In 1919 the
Weimar National Assembly consisted of 421 members; in 1933 the last Reichstag had 647.
Eligible voters and voting procedures In the election to the Weimar National Assembly, the group of eligible voters expanded considerably, from 14,441,400 in 1912 (the
last Reichstag election under the Empire) to 37,362,100 in 1919, primarily because women had been given the right to vote and the voting age was lowered from 25 to 20. Those who could not exercise the right to vote were active duty soldiers, people living in a sanatorium or nursing home and those in criminal or pre-trial detention. Citizenship had to have been obtained at least one year before election day. The election date was set by the Reich president. After November 1918 it had to be a Sunday or a public holiday, in accordance with a long-standing social democratic demand. The Reich was divided into 35 electoral districts (sg. ) that were combined into 16 electoral associations (sg. ). The parties drew up a list of candidates for each electoral district in which they were participating and also a list of candidates at the Reich level. A district received one seat for every 60,000 votes cast for a list, with the first 60,000 votes going to the first candidate on the list (as ranked by the party), the second 60,000 to the second candidate, and so on. Residual votes were transferred to the level of the electoral association. There, the remaining votes from the districts making up the association were added together; for a full 60,000 votes, there was one seat from the district list that had contributed the most residual votes. Any additional remaining votes were carried over to the national level where a party again received one seat (from the national list) per 60,000 votes. A number of additional rules were added to this basic procedure. The most important was that a party could win seats only if it had received 30,000 or more votes in at least one district. Furthermore, a national list could deliver only as many seats as the party had already received in total at the lower levels. These provisions disadvantaged small parties without a regional focus. They nevertheless also resulted in a large number of parties being represented in the Reichstag. Beyond the 30,000 vote hurdle there was no minimum threshold (such as the 5% threshold of
second votes in modern Germany) for a party to enter the Reichstag.

Landtag of Prussia, albeit naturally excluding their territories located in other states. == Presidents and Council of Elders ==
