[3] Hugh was also noted for his support of the new Ottonian dynasty (in Italy since 961), and has been praised for his justice by the contemporary theologian Peter Damian in his De principis officio (On the Office of a Prince).

[3] Hugh's rule has also been remembered for its close cooperation with the Papal States in the resolution of territorial disputes and his generosity in gifting marchesal (public) lands for the foundation of monasteries of the Catholic Church.

[9] Hugh supported Otto III in his ecclesiastical reforms and against Venice, to whose duke, Pietro IV Candiano, he was related.

[1] In 996, Otto placed the eight Adriatic counties[d] disputed between him and the papacy under the joint control of Hugh and Margrave Conrad of Ivrea, also Duke of Spoleto and Camerino, although he also left a missus to oversee the courts and finances.

In a letter dated 5 August 996 Otto tells Pope Gregory V that "we are leaving the foremost men of Italy as aid and comfort to you—Hugh of Tuscany, faithful to us in everything, and Conrad...", and goes on to assure him he would receive "the works and services due" him in the disputed territory.

[e] Hugh and Conrad of Ivrea apparently requested the Empress Theophanu to come to Italy to set matters straight at Bobbio.

Hugh, whose job it was as ruler of Spoleto to maintain the link between the south Italian principalities and the empire,[6] intervened to place Pandulf's youngest son, Laidulf on the Capuan throne and quell the revolt.
