Following the elevation of a commoner into nobility by the Swedish monarch, the new nobleman had to seek "introduction" in order to be a fully recognised member of the House of Nobility "(Riddarhuset)," a term that also refers to its function as a chamber in the Riksdag of the Estates, the Swedish Parliament. In 1866 the Nobility was formally separated from government and incorporated as a separate institution, governed by statutes handed down by the monarch (from 1975: the government). This last link to the government and state was abolished in 2003. The Palace of the Nobility served as official representation for the nobility and was regulated by the Swedish government, but this regulation ceased completely in 2003, as have the privileges. The membership roster is published every three years.
