The Constitution of Liechtenstein was promulgated on 5 October 1921, replacing the 1862 constitution. It was granted by Johann II, Prince of Liechtenstein, and established the rule of parliamentary democracy mixed with that of constitutional monarchy, as well as providing for referendums on decisions of the Landtag. It also abolished the three seats in the Landtag appointed by the Prince and lowered the voting age from 24 to 21.
A referendum on lowering the voting age from 20 to 18 was held in Denmark on 19 September 1978. It was held after the Danish government lowering the age of majority from 20 to 18 in 1976. The change was approved by 53.8% of voters with a turnout of 63.2%. The electoral age had previously been lowered from 21 to 20 in a 1971 referendum, after a 1969 referendum had rejected lowering the electoral age to 18.
A referendum on lowering the voting age from 21 to 20 was held in Denmark on 21 September 1971. The change was approved by 56.5% of voters, with a turnout of 86.2%.

A constitutional and electoral age referendum was held in Denmark on 28 May 1953. Both proposals were approved by voters, leading to both a new constitution taking effect on 5 June, and the electoral age being lowered from 25 to 23 years, also starting on 5 June. Voter turnout was 59.1% for the constitution question and 57.1% for the voting age question.

A referendum on the electoral law was held in Italy on 18 April 1999. Voters were asked whether they approved of replacing the mixed-member proportional representation electoral system with one based solely on single-member constituencies, with the 25% of seats instead allocated to the second-placed in the constituencies with the most votes. The proposal was supported by larger parties, but opposed by smaller ones. Although the proposal was approved by 91.5% of voters, turnout was only 49.6%, resulting in the referendum being invalidated as the threshold of 50% was not passed.
