The Senate of Spain (Spanish: Senado de España) is the upper house of Spain's parliament, the Cortes Generales. It is made up of 264 members: 208 elected by popular vote, and 56 appointed by the regional legislatures. All senators serve four-year terms, though regional legislatures may recall their appointees at any time.
Spanish Senate was instituted by the Constitution of 1837 under the Regency of Maria Christina of the Two Sicilies. It remained under the regime of the Constitutions of 1845, 1856, 1869 and 1876. It was composed at that latter time of three main categories; Senators by their own right, Senators for life and Senators elected. This chamber was suppressed after the Coup of General Miguel Primo de Rivera in 1923.
Only after the Transicion in 1978 was again re-instituted.
