The asylum allowed in the dominions of the emperors to some of
those exiled outlaws, and the imprudent provocations given by these
latter to their adventurous countrymen, attracted various bands
of Norman pirates to the shores of Guelders; and from desultory
descents upon the coast, they soon came to inundate the interior
of the country. Flanders alone successfully resisted them during
the life of Baldwin Bras-de-fer; but after the death of this brave
chieftain there was not a province of the whole country that
was not ravaged by these invaders. Their multiplied expeditions
threw back the Netherlands at least two centuries, if, indeed,
any calculation of the kind may be fairly formed respecting the
relative state of population and improvement on the imperfect
data that are left us. Several cantons became deserted. The chief
cities were reduced to heaps of ruins. The German emperors vainly
interposed for the relief of their unfortunate vassals. Finally,
an agreement was entered into, in the year 882, with Godfrey the
king or leader of the Normans, by which a peace was purchased
on condition of paying him a large subsidy, and ceding to him the
government of Friesland. But, in about two years from this period,
the fierce barbarian began to complain that the country he had
thus gained did not produce grapes, and the present inspiration
of his rapacity seemed to be the blooming vineyards of France.
The emperor Charles the Fat, anticipating the consequence of a
rupture with Godfrey, enticed him to an interview, in which he
caused him to be assassinated. His followers, attacked on all points
by the people of Friesland, perished almost to a man; and their
destruction was completed, in 891, by Arnoul the Germanic. From
that period, the scourge of Norman depredation became gradually
less felt. They now made but short and desultory attempts on the
coast; and their last expedition appears to have taken place
