Matilda of Tuscany
In the same year, the pope and Matilda of Tuscany helped arrange a marriage of Conrad to Maximilla (also called Matilda), a daughter of Count Roger I of Sicily. Maximilla, escorted by Bishop Robert II of Troina, arrived at Pisa with a large fleet and a dowry of "many gifts of treasure". The wedding took place in Pisa in 1095. That same year, Matilda of Tuscany divorced Welf V, whose enraged father, Welf IV, switched allegiance and was restored to the duchy of Bavaria by the emperor in 1096. In 1097, Margrave Adalbert Azzo II died and his vast lands were disputed by his sons. Fulk and Hugh were supporters of Conrad, while Welf IV had sided with the emperor. In a sign of the turning tide, Welf, with the help of Patriarch Udalric and Duke Henry of Carinthia, invaded Italy and secured his claims to the inheritance. This reduced Conrad to total reliance on Matilda of Tuscany.
