The Speaker, or Talman, of the Riksdag is the chairman of the national parliament in Sweden. The new Riksdag was created in 1867, when the old Riksdag of the Estates institution was abolished and included two chambers, each with its own speaker. Since the intoduction of parliamentarism in the 1920s the Riksdag has properly functioned as the Parliament of Sweden. In 1970 the institution underwent changes which transformed it into a unicameral legislative with 349 members as a precursor of the new Constitution of Sweden adopted in 1974.
Under the new Instrument of Government (one of the four fundamental laws of the Constitution) enacted in 1974, that task was removed from the Monarch of Sweden and given to the Speaker of the Riksdag.
The word is also used by Swedish speakers for the parliaments of Finland (it is the official term used by the Swedish-speaking minority there) and Estonia, and for the old Reichstag of Germany as well as the building in Berlin.
