The Constitution of the Principality of Liechtenstein (German: Verfassung des Fürstentums 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 partial parliamentary democracy mixed with that of constitutional monarchy, as well as providing for referendums on decisions of the Landtag.[1] It also abolished the three seats in the Landtag appointed by the Prince and lowered the voting age from 24 to 21.[2] The country replaced universal male suffrage with universal suffrage, following a national referendum in 1984.
