At present, there are twelve monarchies in Europe, of which six are members of the European Union: Belgium, Denmark, Luxembourg, the Netherlands, Spain and Sweden, and six are not: Andorra, Liechtenstein, Monaco, Norway, the United Kingdom and the Vatican City. All six monarchies in the European Union are constitutional monarchies. In all six monarchies that are in the EU, the monarch is legally prohibited from using political power, or the monarch does not utilise the political powers vested in the office by convention. At the dawn of the 20th century, France was the only republic among the future members states of the European Union; the ascent of republicanism to the political mainstream only started at the beginning of the 20th century. In Belgium, the monarchy enjoys a lower degree of support than in other European monarchies, and is often questioned. Popular support for the monarchy has historically been higher in Flanders and lower in Wallonia; however, in recent decades these roles have reversed.
There are three types of government systems in European politics: in a presidential system, the president is the head of state and the head of government; in a semi-presidential system, the president and the prime minister share a number of competences; finally, in a parliamentary republic, the president is a ceremonial figurehead who has few political competences. As with the definition of constitutional monarchies, sometimes the president does have non-ceremonial competences, but does not use them by constitutional convention; this is the case in Austria, for instance. By definition, modern democratic constitutional monarchies are parliamentary, as there is no elected head of state who could assume non-ceremonial competences; of the twenty one republican member states of the European Union, only one is a presidential republic and five are semi-presidential republics. These six presidential republics elect their president by direct popular vote. Among the fourteen parliamentary republics, half do the same, whereas in the remaining seven, the president is elected by parliament or other special representative body such as the German Bundesversammlung.
Degree of self-governance
Most of the European Union's member states are unitary states, which means that most of the competences lie with the central government and only minor or local issues are within the authority of regional governments. However, three states are federations of states or regions with equal competences, and six other states have either devolved certain powers to special regions or are federacies :
A further distinction is the number of chambers in the national legislature; unicameral systems with one chamber or bicameral ones with a lower house and an upper house. Federations and countries with strong regional differences or regional identities are normally bicameral, to reflect the regions' interests in national bills. The states with the larger populations, from the Netherlands upwards, all have a bicameral system. Although there is a greater mix among the smaller states, the smallest states are on the whole unicameral. While there had been legislatures with more than two chambers, nowadays there are only unicameral and bicameral ones. Additionally, there are also differences in the degree of bicameralism. Whereas Italy is considered as having "perfect bicameralism", with both chambers being equal, most other bicameral systems restrict the upper house's powers to a certain extent. There is a slight trend towards unicameralism; some upper houses have seen their powers reduced or proposals to that end. Belgium's system has been reduced from a perfectly bicameral one to a nowadays de facto unicameral system. In 2009, Romania voted in favour of unicameralism, on a plebiscite, however the country still has a bicameral system, as of. On the other hand, Ireland narrowly voted against abolishing their upper house in 2013, and Italy voted not to reduce its Senate's powers in 2016. In the member states of the European Union, if the parliament has only one chamber, it is wholly directly elected in all cases. If there are two chambers, the lower house is directly elected in all cases, while the upper house can be directly elected ; or indirectly elected, for example, by regional legislatures ; or non-elected, but representing certain interest groups.
