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. _HAAKON THE GOOD AND THE SONS OF GUNHILD._ We have told how King Haakon succeeded his brother, Erik Blood-Axe, on the throne, and how, from his kindly and gentle nature, people called him Haakon the Good. There were other sons and several grandsons of Harold the Fair-Haired in the kingdom, but the new king treated them with friendliness and let them rule as minor kings under him. He dealt with the peasants also in the same kindly spirit, giving them back their lands and relieving them of the tax which Harold had laid. But he taxed them all in another way, dividing the country into marine districts, each of which was required to supply the king, on his demand, with a fully equipped warship. Yet as this was for the defence of the country, the people did not look on it as oppressive. And as Norway had a long mountainous coast, and important events were often long in becoming known, he gave orders that the approach of an enemy should be made known by signal fires lighted all along the coast. Haakon made other wise laws, in which he took the advice of the ablest men of the kingdom. But now we have to speak of the most striking event in the new king's career. Norway at that time was a haunt of idolatry. Men worshipped Odin and a host of other gods, and there was not a Christian in the whole land except the king himself, who had been brought up in the new faith by his foster-father, King Athelstan of England. An earnest Christian, he looked with sorrow on the rude worship and heathen belief of his people, but not until he had been many years on the throne did he venture to interfere with it. Then, about 950, when he had won the love of them all, he took steps to carry out his long-cherished desire.
