Landulf

Landulf I (c. 795 – 843), called the Old, was the first gastald (count) of Capua of his illustrious family, which would rule Capua until 1058. According to the Cronaca della dinastia di Capua, he ruled in Old Capua for twenty five years and four months and in New Capua for another year and eight months. According to Erchempert, he was "a very bellicose man" (vir bellicosissimus).

Landulf of Saint Paul (floruit 1077–1137), called Landulf Junior to distinguish him from Landulf Senior, was a Milanese historian whose life is known entirely from his main work, the Historia Mediolanensis. He presents a unique and important point of view from the conflict-ridden years of 1097–1137 in Milan. He thrice sojourned in France while his ecclesiastical faction—the Pataria—was out of favour in Milan, and there learned under some of the leading philosophers of western Europe. After 1113, Landulf's primary ambition was to regain the priesthood in the church of San Paolo which he had lost, and to this end he communicated with popes and emperors. He played a role—large in his own account—in the election of Conrad of Hohenstaufen as King of Italy in 1128.

Landulf of Milan (Italian: Landolfo di Milano, Latin: Landulfus Mediolanensis) was a late eleventh-century historian of Milan. His work Historiae Mediolanensis contains a proportion of pure invention, as well as gross inaccuracies. He is called Landulf Senior to distinguish him from the unrelated chronicler of Milan Landulf Junior.
