Sarzana (Italian: [sarˈdzaːna], Emilian: [sarˈzana]; Ligurian: Sarzann-a)[3] is a town, comune (municipality) and former short-lived Catholic bishopric in the Province of La Spezia, Liguria, Italy.

The position of Sarzana, at the entrance to the valley of the Magra (ancient Macra), the boundary between Etruria and Liguria in Roman times, gave it military importance in the Middle Ages.

During them, a small group of Carabinieri and, later, simple citizens opposed and pushed back some 300 armed Fascists who had come to devastate the town, resulting in 18 dead and about 30 injured.

It was immediately joined in personal union (aeque principaliter) with the bishopric of Brugnato and diocese of La Spezia from 4 August 1975 until their merger on 30 September 1986.

[7] A branch of the Cadolingi di Borgonuovo family, Lords of Fucecchio in Tuscany from the 10th century onwards, which had acquired the name of Buonaparte, had settled near Sarzana before 1264.
