Notes:
Italics denote orders and medals (except commemorative medals) which are not conferred any more.

1. In the Republic the stars of the ribbon bars to the Gold Medals for Military, Naval and Aerial Valor have been encircled by a laurel wreath.
2. By the Royal Decree of 1943 subsequent awards of the War Merit Cross should be denoted by an addition of 1, 2 and 3 bronze, then 1, 2 and 3 silver and 1, 2, 3 gold crowns. Per Republican regulations the crowns were substituted by stars. It seems, however, that despite these regulations a separate ribbon bar was used to denote each new award of the cross.
3. In 2001 the insignia of the Order of Merit of the Italian Republic and the Order of the Star of Italian Solidarity were completely revised; the way of denoting the class on the ribbon was revised too.
4. The Order of St. Maurice & St. Lazarus and the Order of the Crown of Italy, although not part of the current Italian award system, can be worn after the currently awarded orders, provided the small crowns on their ribbon bars are replaced by stars.
5. In 1981 Public Security forces (Pubblica Sicurezza) were replaced by the State Police (Polizia di Stato). Prior to 1981 the State Police Meritorious Service Medal (Medaglia al merito di servizio Polizia di Stato) was called Public Security Long Command Medal (Medaglia di lungo comando Pubblica Sicurezza) and the State Police Long Service Cross (Croce di Anzianita di Servizio Polizia di Stato) was Public Security Long Service Cross (Croce di Anzianita Pubblica Sicurezza). The ribbons of both decorations remained the same.
6. According to one source State Police Long Service Crosses are conferred for 35, 30 and 20 years of service respectively. It is likely that the length of service required for particular classes changed recently. in 1981, its decorations ceased to be awarded.
