Italy

  The disintegration of the ancient Roman empire into small, free territories or towns prevented the introduction of a uniform system of hallmarking on the territory of modern Italy until recent times  Territorial states introduced their own hallmarking systems; in towns, the guilds usually stamped their own hallmarks 
1797  The Republic of Venice on whose territory there had been a uniform system of hallmarking, organized by the state, came to an end. In addition to the city of Venice, this territory included Verona, Brescia, Bergamo and Friuli, part of Istria and nearly the whole of Dalmatia. 
1810  A decree by Napoleon introduced into the Kingdom of Italy a hallmarking system based on the French model, with assay  offices in Milan, Venice, Ancona, Verona and Brescia 
1815-59 (1866)  The French system remained in force on the territory occupied by Austria (Kingdom of Lombardy-Venice), Hallmarking offices were set up in Milan and Venice. 
1818-72  A special system of hallmarking was valid in the principalities of Modena and Parma during this period. 
1873  According to the law of 2 May, 1872, uniform hallmarking for the whole of Italy became valid. Manufacture was liberalized, the control of purity was not obligatory. Purities of 960. 900 and 800/1000 were introduced. 
1936  Introduction of new marks and standards of 926 and 800/1000 valid to this day.
