Giberto IV da Correggio

Giberto IV da Correggio (c. 1320–1373) was a condottiero and signore of Correggio, a small lordship squeezed between Este Ferrara and Visconti Milan. In 1344 Obizzo III d'Este knighted him after he saved Obizzo's life against Feltrino Gonzaga, but in 1346 Luchino Visconti took Guastalla from him.

He came to terms with the Visconti in 1354, broke with them in 1361 and joined Charles IV's anti-Visconti league in 1368. In 1372, while Giberto was at Ferrara, his nephew Guido seized Correggio and imprisoned his sons.

Stripped of his lordship, Giberto became a general of Venice against the Carraresi of Padua. Beaten at Lova, he made up for it at Piove di Sacco by capturing Rizzardo di Sambonifacio, and died in Venice in 1373.
