The civil registry was introduced in Italy in 1806, after the annexation of many Italian regions to the French Empire and the implementation of the new Civil Code, which was in force until 1815.
In the old Kingdom of the Two Sicilies, which corresponds to the Southern continental Italy, and in the Duchy of Modena and Reggio, the civil registry was established in 1809. In Sicily the civil registry was introduced only in 1820.
In the Grand Duchy of Tuscany, a mix system was introduced after the Restoration: the Decree of June 18, 1817 introduced the Civil Registry, a government agency attached to the Royal Secretary of Law responsible for the coordination and surveillance of priest and chancellors in matters of civil registry and document management. The same thing happened in the Kingdom of Sardinia since 1837, when the “Rulebook for the preservation of Civil Registry documents was introduced as an annex of the “Letters Patent” of 20 June, 1837.
Only since 1866 the Civil Registry works uninterruptedly in all Italian regions and provinces. Obviously, there are some exceptions: Lazio and Rome were incorporated to Italy in 1870, Veneto and Friuli in 1871 – except Southern Tirol and Alto Adige, incorporated in 1918, after World War I.
