Political Institutions

The Grand Duchy of Luxembourg has been an independent sovereign state since the Treaty of London of 19 April 1839. Luxembourg is a parliamentary democracy in the form of a constitutional monarchy. The crown of the Grand Duchy is hereditary in the Nassau-Weilbourg family. Luxembourg also has a distinctive characteristic: it's the only Grand Duchy in the world.

In 1919, the revision of the Constitution and the introduction of universal suffrage marked a turning point in the political life of the Grand Duchy. Before this date, the right to vote was subject to a poll tax, in other words a certain amount of tax paid, and restricted to the male population aged 25 and over. After the the revision of 1919, all male and female citizens who had reached the age of 21 were given the right to vote. In 1972, the voting age was reduced to 18.

Luxembourg is a democratic state. Under the Constitution, the nation is the source of sovereign power and the Grand Duke takes the constitutional oath before the representatives of the sovereign nation when acceding to the throne.

The nation exercises its sovereignty indirectly via its representatives, who are elected to the Chambre des députés (Chamber of Deputies), Luxembourg's parliament.
