The raiders were Scandinavians--‘Vikings,’[B] as they have come to be called, from the fact that their settlements, though scattered all over the Baltic region, lay thickest in the ‘viks’ (fjords), and especially along the shores of the great ‘Vik,’ the Skager-Rak and Christiania Fjord. All these communities were ready, on slight pretext, to take to warfare and plunder, and leaders were never wanting. Politics, economic conditions, and mere half-savage love of adventure, all played their part in driving them seaward; and once the Vikings had tasted plunder, desire of more soon led them far afield. [B] The ‘i’ in Viking is short. The Scandinavians were as yet heathens, and were to continue so for long centuries. They were not altogether barbarians, despite the savagery which appears so terribly in their deeds. Their social condition was well developed, and they were not without a tincture of civilized culture and art. In metal-work their achievements were notable. They had long been renowned as boat-builders. Tacitus especially notes their proficiency in that science. It does not appear, however, that they took any part in the Teutonic attacks on the Roman Empire, but in 515 a Danish chief named Hygelac raided the coast of Frankland. He was defeated and slain by Theudebert I. It was, perhaps, the conquest of the Saxons by Charles the Great which alarmed the Danes into attacking Christendom. Before 793 scarcely anything is heard of hostility from them. But Denmark, bordering on Saxony, naturally became the refuge of the Saxon chiefs, and was gradually drawn into the conflict. About 800 King Godfrid took up a position of open hostility to the new “Roman” Emperor of the West. In 808 Charles apparently meditated an invasion of Denmark, and in 810 a Danish fleet of two hundred sail ravaged Frisia. Two years later Godfrid prepared to invade the Frankish Empire, but was assassinated. His successor sued for terms, and Charles the Great died in peace. Nevertheless, the impulse had been given, and from 793 onward Viking ravages began to afflict Europe. For many years they were confined mainly to Ireland, which was wasted almost from sea to sea, the result being, of course, that its brilliant art and literature were steadily destroyed. The wasters of Ireland appear to have been chiefly Norwegians; Denmark was involved in civil war. Frankland, no doubt, appeared too powerful to annoy with impunity. England also seemed strong. The raids of 793-794 were directed on anarchic Northumbria.
