The Senate (, ; , ; ) is one of the two chambers of the bicameral Federal Parliament of Belgium, the other being the Chamber of Representatives. It is considered to be the "upper house" of the Federal Parliament. Created in 1831 as a chamber fully equal to the Chamber of Representatives, it has undergone several reforms in the past, most notably in 1993 and 2014. The 2014 elections were the first without a direct election of senators. Instead, the new Senate is composed of members of community and regional parliaments and co-opted members. It is a chamber of the communities and regions and serves as a platform for discussion and reflection about matters between these federated entities. The Senate today plays a minor role in the federal legislative process. However, the Senate, together with the Chamber, has full competence for the Constitution and legislation on the organization and functioning of the Federal State and the federated entities. Since the reform of 2014, it holds about ten plenary sessions a year. History After the Belgian Revolution of 1830, the National Congress decided on the Belgian Constitution and the state structure. Belgium would become a unitary state. A bicameral Parliament was chosen over a unicameral one. The Senate was seen as a more conservative and elite body that served as a counterweight to the more progressive Chamber of representatives. Senators were directly elected, but only those who paid ground taxes were eligible. Only men who paid taxes were allowed to vote. There was also the possibility for the heir to the throne to become senator by right. In 1893 the principal of universal multiple voting right was introduced for men. This was combined with the principle of compulsory voting and the principle of proportional representation. For the Senate, candidates still needed to pay ground taxes, but the threshold was lowered. Moreover, a new category of provincial senators was introduced. After World War I, the single vote system - "one man, one vote" - was introduced. This principle of universal suffrage was only applicable to men, women had no right to vote. They however could be a candidate in elections. 1921 saw a new reform for the Senate. The prerequisite of taxes was abolished and 4 categories of senators were created: directly elected senators, provincial senators, co-opted senators and senators by right. In 1936, Maria Baers and became the first women senators.
