Venstre (which means "Left" in Norwegian) was the party advocating parliamentarism, whereas the conservatives, who opposed parliamentarism, formed the party Høyre (which means "Right"). When the fight for parliamentarism was won, Venstre's leader Johan Sverdrup became the first Norwegian prime minister to be appointed on the basis of having the support of a majority in the Storting. Later, Venstre advocated universal suffrage for men, which was achieved in 1898, the break-up of the Swedish-Norwegian Union, which happened in 1905, and universal women's suffrage, which was introduced in 1913.
