The Senate () is the upper house in the bicameral Parliament of Romania. It has 136 seats (before the 2016 Romanian legislative election the total number of elected representatives was 176), to which members are elected by direct popular vote using party-list proportional representation in 43 electoral districts (the 41 counties, the city of Bucharest plus 1 constituency for the Romanians living abroad), to serve four-year terms. History First Senate (1859–1944) The parliamentary history of Romania is seen as beginning in May 1831 in Wallachia, where a constitution called Regulamentul Organic ("Organic Statute") was promulgated by the Russian Empire and adopted. In January 1832 it came into force in Moldavia also. This laid the foundations for the parliamentary institution in the two Romanian principalities. At the Congress of Paris of 1856, Russia gave up to Moldavia the left bank of the mouth of the Danube, including part of Bessarabia, and also gave up its claim to be the protector of Christians in the Ottoman Empire. Moldavia and Wallachia, while remaining under the suzerainty of the Ottomans, were recognized as quasi-independent self-governing principalities under the protection of the other European Powers. The Paris Convention of 19 August 1858 promulgated Statutul Dezvoltător ("Expanding Statute"), to introduce a bicameral parliament, with an upper house named in Romanian Corpul Ponderator ("Moderating Body"). This was later renamed the Senat. A formal Union of the two principalities came in 1859. On the initiative of Alexandru Ioan Cuza, a plebiscite in 1864 enlarged the principle of national representation. The 1866 Constitution of Romania proclaimed constitutional monarchy as Romania's form of government, on the basis of national sovereignty and the separation of powers. Legislative power was to be exercised by the new Prince (Carol I of Romania) and a bi-cameral parliament, with an Assembly of Deputies and a Senate. On 9 May 1877, the Declaration of Romania's independence was read under the dome of the Romanian Parliament. The 1923 Constitution, approved by both houses of parliament in May 1923, again entrusted legislative power to the Senate, the Assembly of Deputies, and the King. The constitution instituted the membership by right (senator de drept) in the Senate for: The heir to the throne; Metropolitan bishops and diocesan bishops of the Orthodox and Greek-Catholic churches; Heads of state-recognised religious bodies; The president of the Romanian Academy; Former presidents of the Council of Ministers; Former ministers with at least six years'
