In 1037 Bonifazio had taken to wife Beatrice of Lorraine, who in 1046 gave birth to a daughter, Matilda, the celebrated countess or _comitissa_, as she is entitled by the chroniclers. After the death of Bonifazio, by assassination, in 1052, Matilda was soon associated with her mother in the government of Tuscany and of the whole duchy, and when left an orphan in 1076, became sole ruler of those extensive dominions. Beatrice had remarried, and as she was very religious, and her second husband, Goffredo of Lorraine, was brother to Pope Stephen IX., this served to increase their common zeal for the papal policy, afterwards so devotedly pursued by Matilda. When this high-minded, energetic woman became sole ruler, she held the reins of government in a firm grasp, and was often seen on battle-fields with a sword at her side. Her political position was one of great peril, for she was driven to take part in the fierce quarrel, recently begun, between the Church and the Empire. At first the great, high-tempered Hildebrand conducted the struggle as the inspiring genius of various Popes; later on, when raised to the pontifical Chair as Gregory VII., he fought in person against Henry IV. of Germany, and found Matilda his strongest and best ally. In this conflict, stirring and dividing all Europe, it was only natural that many opposing passions should be excited in Italy. All cities that, like Pisa and Lucca, considered themselves wronged by Duke Bonifazio, now declared for the Empire, and the Empire sided with them against Matilda. The same course was followed by all dissatisfied feudatories, especially by those whom Bonifazio had stripped of their possessions. More than once, it is true, Countess Matilda seized estates which had been arbitrarily alienated; but she seldom restored them to their original owners, preferring instead to bestow them on churches, convents, and trusty adherents of her own. This added fresh fuel to the flame. Hence an increasingly tangled web of opposing passions, of conflicting interests, from which at last some profit accrued to Florence. The Guelph spirit of the city and its commercial position, on the highway to Rome, had from the outset inclined it to the Church, and now, as a declared ally, was actively favoured by Beatrice and Matilda.
