The Riksakten was the 1815 Act of Union that regulated the terms of the constitutional personal union between Sweden and Norway established in 1814. The fundamental documents of the union were only the Convention of Moss and the revised Norwegian constitution of 4 November 1814. The Norwegian constitution had been adapted to the union before it was entered into, but the Swedish one was never adjusted correspondingly. The conservative Swedish Riksdag had not allowed the Swedish constitution of 1809 to be revised. Therefore, a bilateral treaty had to be negotiated in order to clarify procedures for treating constitutional questions that had to be decided jointly by both governments.
