The Frankfurt National Assembly (German: Frankfurter Nationalversammlung) was the first freely elected parliament for all German states, including the German-populated areas of the Austrian Empire, elected on 1 May 1848 (see 1848 German federal election).
The session was held from 18 May 1848 to 30 May 1849 in the Paulskirche at Frankfurt am Main. Its existence was part of the result of the "March Revolution" within the states of the German Confederation.
After long and controversial debates, the assembly produced the so-called Frankfurt Constitution (Paulskirchenverfassung or St. Paul's Church Constitution, officially the Verfassung des Deutschen Reiches) which proclaimed a German Empire based on the principles of parliamentary democracy.
