Count Dirk II added Maasland, Kennemerland and the island of Texel
to his domain. This was formally acknowledged by Emperor Otto III
as a reward for his support. At about 940, Dirk II extended his
influence southwards by marrying Hildegard, daughter of the Count
of Flanders, a descendant of Charlemagne and a great-granddaughter of
Alfred the Great, King of England. Dirk II and Hildegard replaced
the wooden church of Egmond with a stone Abbey church where both of
them were buried.
