Adalbert II, Margrave of Tuscany
Adalbert II (c. 875–915), called the Rich, son and successor of Adalbert I, Margrave of Tuscany, and grandson of Boniface II, was much concerned in the troubles of Lombardy, at a time when so many princes were contending for the wreckage of the Carolingian Empire. Before his father died in 884 or 886, he is accredited the title of "count". He inherited from his father the titles of Count and Duke of Lucca and Margrave of Tuscany.
