In Norway, dissension on constitutional questions led to the "de facto" adoption of parliamentarism in 1884, after an impeachment process against the conservative cabinet of Christian August Selmer. The cabinet was accused of assisting the king in obstructing reform by veto. The new liberal government of Johan Sverdrup was reluctantly installed by King Oscar. It immediately implemented important reforms, among them extended suffrage and compulsory military service. The two opposite groups established formal political parties in 1884, "Venstre" (Left) for the liberals, who wanted to dissolve the Union, and "Højre" (Right) for conservatives, who wanted to retain a union of two equal states.
