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 about the year 1000, when they threatened, but did not succeed in seizing on, the city of Utrecht. It is remarkable that, although for the space of one hundred and fifty years the Netherlands were continually the scene of invasion and devastation by these northern barbarians, the political state of the country underwent no important changes. The emperors of Germany were sovereigns of the whole country, with the exception of Flanders. These portions of the empire were still called Lorraine, as well as all which they possessed of what is now called France, and which was that part forming the appanage of Lothaire and of the Lotheringian kings. The great difficulty of maintaining subordination among the numerous chieftains of this country caused it, in 958, to be divided into two governments, which were called Higher and Lower Lorraine. The latter portion comprised nearly the whole of the Netherlands, which thus became governed by a lieutenant of the emperors. Godfrey count of Ardenne was the first who filled this place; and he soon felt all the perils of the situation. The other counts saw, with a jealous eye, their equal now promoted into a superior. Two of the most powerful, Lambert and Reginald, were brothers. They made common cause against the new duke; and after a desperate struggle, which did not cease till the year 985, they gained a species of imperfect independence--Lambert becoming the root from which sprang the counts of Louvain, and Reginald that of the counts of Hainault.
