The Reichstag (German for “National Diet” or “Imperial Diet”) was the parliament of the North German Confederation (1867–1870), and of the German Reich (1871–1945).
German constitution commentators consider only the Reichstag and now the Bundestag the German parliament. Another organ dealt with legislation too, in 1867-1918 the Bundesrat, in 1919–1933 the Reichsrat and from 1949 on the Bundesrat. The Bundesrat or Reichsrat represents the German states.
After the collapse of the Empire in 1806, the term was subsequently used for the Parliament of the 1849 Frankfurt constitution draft that never came into effect, the Parliament of the North German Confederation from 1867–1871 and finally that of the 1871 German Empire. Eligible to vote were all male Germans over 25 years. According to contemporary standards this was considered a modern and progressive parliament.[1] The deputies were chosen in one member constituencies, with majority vote. If necessary, a second vote took place.
The Reichstag had no formal right to install or dismiss the government. Legislation was shared between both the Reichstag and the (then) Bundesrat, which was the council of the reigning princes of the German states. Source Wikipedia
