But now a new force was appearing in the Mediterranean. We have already remarked that the Roman Empire never extended itself to the shores of the Baltic Sea, nor had ever the vigour to push itself into Denmark. The Nordic Aryan peoples of these neglected regions learnt much from the empire that was unable to subdue them; as we have already noted in § 4, they developed the art of shipbuilding and became bold seamen; they spread across the North Sea to the west, and across the Baltic and up the Russian rivers into the very heart of what is now Russia. One of their earliest settlements in Russia was Novgorod the Great. There is the same trouble and confusion for the student of history with these northern tribes as there is with the Scythians of classical times, and with the Hunnish Turkish peoples of Eastern and Central Asia. They appear under a great variety of names, they change and intermingle. In the case of Britain, for example, the Angles, the Saxons, and Jutes conquered most of what is now England in the fifth and sixth centuries; the Danes, a second wave of practically the same people, followed in the eighth and ninth; and in 1013 a Danish King, Canute, reigned in England, and not only over England, but over Denmark and Norway. For a time, under Canute and his sons, it seemed possible that a great confederation of the Northmen might have established itself. Then in 1066 a third wave of the same people flowed over England from the “Norman” state in France, where the Northmen had been settled since the days of Rolf the Ganger (912), and where they had learnt to speak French. William, Duke of Normandy, became the William the Conqueror (1066) of English history. Practically, from the standpoint of universal history, all these peoples were the same people, waves of one Nordic stock. These waves were not only flowing westward, but eastward. Already we have noted (chap, xxix, § 4), a very interesting earlier movement of the same peoples under the name of Goths from the Baltic to the Black Sea. We have traced the splitting of these Goths into the Ostrogoths and the Visigoths, and the adventurous wanderings that ended at last in the Ostrogoth kingdom in Italy and the Visigoth states in Spain. In the ninth century a second movement of the Northmen across Russia was going on at the same time that their establishments in England and their dukedom of Normandy were coming into existence. The populations of South Scotland, England, East Ireland, Flanders, Normandy, and the Russias have more elements in common than we are accustomed to recognize. All are fundamentally Gothic and Nordic peoples. These “Russian” Norsemen travelled in the summer-time, using the river routes that abounded in Russia; they carried their ships by portages from the northward-running rivers to those flowing southward. They appeared as pirates, raiders, and traders both upon the Caspian and the Black Sea. The Arabic chroniclers note their apparition upon the Caspian, and give them the name of Russians. They raided Persia, and threatened Constantinople with a great fleet of small craft (in 865, 904, 941, and 1043).[348] One of these Northmen, Rurik (circa 850), established himself as the ruler of Novgorod and Kief, and laid the foundations of modern Russia. The fighting qualities of the Russian Vikings were speedily appreciated at Constantinople; the Greeks called them Varangians, and an Imperial Varangian bodyguard was formed. After the conquest of England by the Normans (1066), a number of Danes and English were driven into exile and joined these Russian Varangians, apparently finding few obstacles to intercourse in their speech and habits.
Meanwhile the Normans from Normandy were also finding their way into the Mediterranean from the West. They came first as mercenaries, and later as independent invaders; and they came mainly, not, it is to be noted, by sea, but in scattered bands by land. They came through the Rhineland and Italy partly in the search for warlike employment and loot, partly as pilgrims. For the ninth and tenth centuries saw a great development of pilgrimage. These Normans, as they grew powerful, discovered themselves such rapacious and vigorous robbers that they forced the Eastern Emperor and the Pope into a feeble and ineffective alliance against them (1053). They defeated and captured and were pardoned by the Pope; they established themselves in Calabria and South Italy, conquered Sicily from the Saracens (1060-1090), and under Robert Guiscard, who had entered Italy as a pilgrim adventurer and began his career as a brigand in Calabria, threatened the Byzantine Empire itself (1081). His army, which contained a contingent of Sicilian Moslems, crossed from Brindisi to Epirus in the reverse direction to that in which Pyrrhus had crossed to attack the Roman Republic, thirteen centuries before (275 B.C.). He laid siege to the Byzantine stronghold of Durazzo.
Robert captured Durazzo (1082), but the pressure of affairs in Italy recalled him, and ultimately put an end to this first Norman attack upon the Empire of Byzantium leaving the way open for the rule of a comparatively vigorous Comnenian dynasty (1081-1204). In Italy, amidst conflicts too complex for us to tell here, it fell to Robert Guiscard to besiege and sack Rome (1084); and Gibbon notes with quiet satisfaction the presence of a large contingent of Sicilian Moslems amongst the looters. There were in the twelfth century three other Norman attacks upon the Eastern power, one by the son of Robert Guiscard, and the two others directly from Sicily by sea....
But neither the Saracens nor the Normans pounded quite so heavily against the old empire at Byzantium or against the Holy Roman Empire, the vamped-up Roman Empire of the West, as did the double thrust from the Turanian centres in Central Asia, of which we must now tell. We have already noted (chap. xxix, § 5) the westward movement of the Avars, and the Turkish Magyars who followed in their track. From the days of Pepin I onward, the Frankish power and its successors in Germany were in conflict with these Eastern raiders along all the Eastern borderlands. Charlemagne held and punished them, and established some sort of overlordship as far east as the Carpathians; but amidst the enfeeblement that followed his death, these peoples, more or less blended now in the accounts under the name of Hungarians, led by the Magyars, re-established their complete freedom again, and raided yearly, often as far as the Rhine. They destroyed, Gibbon notes, the monastery of St. Gall in Switzerland, and the town of Bremen. Their great raiding period was between 900 and 950. Their biggest effort, through Germany right into France, thence over the Alps and home again by North Italy, was in 938-9.
Thrust southward by these disturbances, and by others to be presently noted, the Bulgarians, as we have told in § 5, established themselves under Krum, between the Danube and Constantinople. Originally a Turkish people, the Bulgarians, since their first appearance in the east of Russia, had become by repeated admixture almost entirely Slavonic in race and language. For some time after their establishment in Bulgaria they remained pagan. Their king, Boris (852-884), entertained Moslem envoys, and seems to have contemplated an adhesion to Islam, but finally he married a Byzantine princess, and handed himself and his people over to the Christian faith.
