Analysis of landholdings in the march of Tuscany is substantially founded on relationships with some of the wealthier and more significant monastic institutions in the region. Behind these were the relationships attained in the institutional sphere essential for the kindred to settle in this area of the kingdom. Bonds built with the Florentine bishops and the Adalbertings stand out above all others. Once the Hucpoldings had, however, reached their paramount political and social dominance, it was the Benedictine monasteries which were the main patrimonial intermediaries in all territorial environments across the march.

The city of Florence and its territory represented the centre of reference from as early as the middle of the ninth century. In the city centre the abbadiola of S. Andrea was controlled for at least three generations with the blessing of the city's bishop. The final decades of the tenth century saw the independent foundation of the monastery of S. Maria, the so-called Badia fiorentina, which became one of the most powerful monasteries in the whole of Tuscany, due to the consistent endowment of Willa and the Marquises Hugh and Boniface II. Also in the Florence area, we find traces of the almost century-old relationships with the church of S. Salvatore a Settimo to the west of Florence.

Control of the march, together with Hugh I's prestigious ascendancy gave him the opportunity to increase his power and influence over the whole Tuscan territory, thus playing a key role during the reign of Otto III.
