But the Irish at length got rid of their conqueror by a stratagem. It was through love that the sea-king was lost. Bewitched with the charms of the fair daughter of Maelsechnail, one of the petty kings of the land, he bade this chieftain to send her to him, with fifteen young maidens in her train. He agreed to meet her on an island in Loch Erne with as many Norsemen of high degree.
Maelsechnail obeyed, but his maidens were beardless young men, dressed like women but armed with sharp daggers. Thorgisl and his men, taken by surprise, were attacked and slain. The Irish chief had once before asked Thorgisl how he should rid himself of some troublesome birds that had invaded the island. "Destroy their nests," said the Norseman. It was wise advice, and Maelsechnail put it in effect against the nests of the conquerors, destroying their stone strongholds, and killing or driving them away, with the aid of his fellow chieftains.
Thus for a time Ireland was freed. It was conquered again by Olaf the White, who in 852 defeated some Danes who had taken Dublin, and then, like Thorgisl, began to build castles and tax the people. Two other viking leaders won kingdoms in Ireland, but Olaf was the most powerful of them all, and the kingdom founded by him lasted for three hundred and fifty years. From Dublin Olaf sailed to Scotland and England, the booty he won filling two hundred ships.
The sea-rovers did not confine their voyages to settled lands. Bold ocean wanderers, fearless of man on shore and tempest on the waves, they visited all the islands of the north and dared the perils of the unknown sea. They rounded the North Cape and made their way into the White Sea as early as 750. The Faroe, the Orkney and the Shetland Islands were often visited by them after 825, and in 874 they discovered Iceland, which had been reached and settled by Irishmen or Scots about 800. The Norsemen found here only some Irish hermits and monks, and these, disturbed in their peaceful retreat by the turbulent newcomers, made their way back to Ireland and left the Norsemen lords of the land. From Iceland the rovers reached Greenland, which was settled in 986, and about the year 1000 they discovered North America, at a place they named Vinland.
Such is, briefly told, the story of the early Norse wanderers. They had a later tale, of which we have told part in their conquest of Ireland. Though at first they came with a few ships, and were content to attack a town or a monastery, they soon grew more daring and their forces larger. A number of them would now fortify themselves on some coast elevation and make it a centre for plundering raids into the surrounding country. At a later date many of them ceased to pose as pirates and took the rôle of invaders and conquerors, storming and taking cities and founding governments in the invaded land.
Such was the work of Thorgisl and Olaf in Ireland and of Rollo in Normandy. England was a frequent field of invasion after 833, which continued until 851, when King Ethelwulf defeated them with great slaughter. Fifteen years later they came again, these new invaders being almost all Danes. During all his reign Alfred the Great fought with them, but in spite of his efforts they gained a footing in the island, becoming its masters in the north and east. A century later, in 1016, Canute, the king of Denmark, completed the conquest and became king of all England.
This is not the whole story of the sea-kings, whose daring voyages and raids made up much of the history of those centuries. One of the most important events in viking history took place in 862, when three brother chiefs, probably from Sweden, who had won fame in the Baltic Sea, were invited by the Russian tribes south of Lake Ladoga to come and rule over them. They did so, making Novgorod their capital. From this grew the empire of Russia, which was ruled over by the descendants of Rurik, the principal of these chiefs, until 1598.
Other vikings made their way southward through Russia and, sailing down the Dnieper, put Constantinople in peril. Only a storm which scattered their fleet saved the great city from capture. Three times later they appeared before Constantinople, twice (in 904 and 945) being bought off by the emperors with large sums of money. Later on the emperors had a picked body-guard of Varangians, as they called the Northmen, and kept these till the fall of the city in 1453. It was deemed a great honor in the north to serve in this choice cohort at Myklegaard (Great City), and those who returned from there doubtless carried many of the elements of civilization to the Scandinavian shores.
To some of these Varangians was due the conquest of Sicily by the Northmen. They were in the army sent from Constantinople to conquer that island, and seeing how goodly a land it was they aided in its final conquest, which was made by Robert Guiscard, a noble of Normandy, whose son Roger took the title of "King of Sicily and Italy." Thus it was that the viking voyages led within a few centuries to the founding of kingdoms under Norse rulers in England, Ireland, Sicily, Russia, and Normandy in France.
