Camillo Benso, Count of Cavour
Elsewhere in Europe, centre-left movements appeared from the 1860s, mainly in Spain and Italy. In Italy, the centre-left was born as coalition between the liberal Camillo Benso, Count of Cavour and the progressive Urbano Rattazzi, the heads respectively of the Right and Left groupings in Parliament. This alliance was called "connubio" ("marriage") for its opportunist characteristics. In the 1900s, centre-left positions were expressed by people and parties who believed in social democracy and democratic socialism, but also some liberals or Christian-democrats were associated with the centre-left. Currently, the centre-left parties in Europe are united in the social democratic Party of European Socialists and ecologist European Green Party.
