Editing Althing (section)

=== Personal union ===
The [[Danish–Icelandic Act of Union|Act of Union]] (which took effect on 1 December 1918) made Iceland a [[Sovereign state|state]] in [[personal union]] with the [[Denmark|Kingdom of Denmark]]. It was set to expire after 25 years, when either state could choose to leave the union. The Althing was granted unrestricted legislative power. In 1920, the number of members of the Althing was increased to 42. Since 1945, the Althing has customarily assembled in the autumn. With the [[Constitutional Act of 1934]], the number of members was increased by seven and the system of national representatives abolished in favour of one providing for eleven seats used to equalize discrepancies between the parties' [[Direct election|popular vote]] and the number of seats they received in the Althing, raising the number of members of the Althing to 49. In 1934, the voting age was also lowered to 21. Further changes in 1942 provided for an additional three members and introduced proportional representation in the double-member constituencies. The constituencies were then 28 in number: 21 single-member constituencies; six double-member constituencies; and Reykjavík, which elected eight members. With the additional eleven equalization seats, the total number of members was thus 52.<ref name="ath"/>
