In the meantime Offa, that the outrages against his countrymen might not secretly tend to his disadvantage, in order to conciliate the favour of neighbouring kings, gave his daughter Eadburga in marriage to Bertric, king of the West Saxons; and obtained the amity of Charles the Great, king of the Franks, by repeated embassies, though he could find little in the disposition of Charles to second his views. They had disagreed before, insomuch that violent feuds having arisen on both sides, even the intercourse of traders was prohibited. There is an epistle of Alcuin to this effect, part of which I shall subjoin, as it affords a strong proof of the magnanimity and valour of Charles, who spent all his time in war against the Pagans, rebels to God. He says,[108] “The ancient Saxons and all the Friesland nations were converted to the faith of Christ through the exertions of king Charles, urging some with threats, and others with rewards. At the end of the year the king made an attack upon the Sclavonians and subjugated them to his power. The Avares, whom we call Huns, made a furious attempt upon Italy, but were conquered by the generals of the aforesaid most Christian king, and returned home with disgrace. In like manner they rushed against Bavaria, and were again overcome and dispersed by the Christian army. Moreover the princes and commanders of the same most Christian king took great part of Spain from the Saracens, to the extent of three hundred miles along the sea-coast: but, O shame! these accursed Saracens, who are the Hagarens, have dominion over the whole of Africa, and the larger part of Asia Major. I know not what will be our destination, for some ground of difference, fomented by the devil, has arisen between king Charles and king Offa, so that, on both sides, all navigation is prohibited the merchants. Some say that we are to be sent into those parts to treat of peace.” In these words, in addition to what I have remarked above, any curious person may determine how many years have elapsed since the Saracens invaded Africa and Asia Major. And indeed, had not the mercy of God animated the native spirit of the emperors of the Franks, the pagans had long since subjugated Europe also. For, holding the Constantinopolitan emperors in contempt, they possessed themselves of Sicily and Sardinia, the Balearic isles, and almost all the countries surrounded by the sea, with the exception of Crete, Rhodes, and Cyprus. In our time however they have been compelled to relinquish Sicily by the Normans, Corsica and Sardinia by the Pisans, and great part of Asia and Jerusalem itself by the Franks and other nations of Europe. But, as I shall have a fitter place to treat largely of these matters hereafter, I shall now subjoin, from the words of Charles himself, the treaty which was ratified between him and Offa king of the Mercians.
