Arnulf II of Flanders was Count of Flanders from 965 until his death.
He was the son of Baldwin III of Flanders and Matilda of Saxony. Baldwin III died in 962, when Arnulf was just an infant, and with Arnulf's grandfather count Arnulf I of Flanders still alive. When Arnulf I died three years later (965), the regency was held by their kinsman Baldwin Balso.
By the time Arnulf attained his majority in 976, Flanders had lost some of the southern territory acquired by Arnulf I. The latter had given some parts of Picardy to King Lothar of France to help assure his grandson's succession, and gave Boulogne as a fief to another relative. Then early in Arnulf's minority Lothar had taken Ponthieu and given it to Hugh Capet, and the first counts of Guines had established themselves.
He married Rozala of Lombardy, daughter of Berengar II of Italy, and was succeeded by their son, Baldwin IV.
Arnulf married Suzanne "Rosala"de Lombardy Princess of Italy, daughter of King Berengar II of Italy and Willa Princess Of Tuscany. (Suzanne "Rosala"de Lombardy Princess of Italy was born about 960 in Ivrea, died on 26 Jan 1003 in Ghent, East Flanders, Belgium and was buried in Ghent, East Flanders, Belgium.)
