The first settlers in the area were the Sidicini; the
Etruscans founded here the town of
Cesennia, which later passed under
Roman control. After the fall of the
Western Roman Empire, Mignano became part of the
Lombard Duchy of Benevento and, in 776, part of the
County of Capua. In 1139 the nearby
Galluccio was the seat of a successful ambush of
Roger II of Sicily's troops against the army of
Pope Innocent II, who, captured, was forced to sign a
treaty of peace in the Mignano castle. After the
Hohenstaufen and
Angevine domination, the
Aragonese gave it as a fief to
Ettore Fieramosca. In 1581 his heir Ettore Leognano Fieramosca ceded it to Giulio Cesare De Capua. In 1734 the troops of
Charles of Bourbon besieged here Marshal
von Traun, who had to flee to
Capua. During World War II Mignano was the seat of fierce fightings, part of the
Battle of San Pietro Infine. In order to facilitate their escapement, the German destroyed the fortress and the bridge on the
Rava. The nearby Monte Lungo was conquered on December 16, 1943, by the Italian
1° Raggruppamento Motorizzato. ==Main sights==
