Note about the coloring: Every combination which appears at least twice has been assigned a color. The Conservative Party is an ancestor of the Independence Party and here counted as such.

Note about Magnús Guðmundsson: Jón Magnússon died June 23 1926. Magnús Guðmundsson acted as PM until Jón Þorláksson could be reached. Officially the third cabinet of Jón Magnússon is said to have been in office until July 8 1926, but as the PM was dead, it seemed proper to include the acting PM in the list.

Abbreviations

• CiP: Citizens' Party (Borgaraflokkurinn). Extinct.
• CP: Conservative Party (Íhaldsflokkurinn). Extinct.
• HP: Home Rule Party (Heimastjórnarflokkurinn). Extinct.
• IP: Independence Party (Sjálfstæðisflokkurinn).
• LL: Association of Liberals and Leftists (Samtök frjálslyndra og vinstri manna). Extinct.
• OIP: The old Independence Party (no relation to the current one). OIP langsum and OIP þversum denote two fractions that split the party at one time. Extinct.
• PA: The People's Alliance (Alþýðubandalagið). Extinct.

All but two parties are labelled extinct. That only means that they no longer exist under those names. Apart from the Independence Party and the Progressive Party, the following possess parliamentary seats: The Union of Leftists (Samfylkingin, mostly former Social Democrats), The Left-Green Movement (Vinstri hreyfingin - grænt framboð, mostly former Socialists) and The Liberal Party (Frjálslyndi flokkurinn, followers from all over the spectrum). Those last three have never been in government in their current incarnations.
