Liberal Left Party
The party had a close cooperation with the Conservative Party, and was part of multiple Governments, including Konow's Cabinet, Bratlie's Cabinet, Bahr Halvorsen's First and Second Cabinet, Berge's Cabinet and Lykke's Cabinet. Both Abraham Berge and Wollert Konow (SB) were Prime Ministers from the party.
The party received 26 representatives in Parliament of Norway in the 1909 election, but the numbers sank, and by the 1933 election the party was without seats. In 1933 the party changed its name to the Liberal People's Party (Frisinnede Folkeparti). Part of the explanation for the defeat in the 1933 election has been credited to the electoral cooperation with National Unification (NS). After the defeat the party leaned closer towards NS, which gave even worse results in the 1936 elections. By then most members had joined the Conservatives, and in 1945 the party was formally dissolved to the advantage of the Conservatives. Among the politicians who remained members of the Liberal People's Party until 1945 were later Prime Minister John Lyng.
The party leaders were Abraham Berge (1909–1910), Magnus Halvorsen (1910–1912), Erik Enge (1915–1918), Bernt Holtsmark (1918–1922), Oluf Christian Müller (1922–1924), Karl Wefring (1924–1925), P. A. Holm (1925–1930), Anton Wilhelm Brøgger (acting, 1930–1931) Einar Greve (1931–1933) and Rolf Thommessen (1933).
