After four or five months of tentative measures or of incidents which taught both parties that they could not, either of them, hope to completely destroy their opponents, the two allied brothers received at Verdun, whither they had repaired to concert their next movement, a messenger from Lothaire, with peaceful proposals which they were unwilling to reject. The principal was that, with the exception of Italy, Aquitaine, and Bavaria, to be secured without dispute to their then possessors, the Frankish empire should be divided into three portions, that the arbiters elected to preside over the partition should swear to make it as equal as possible, and that Lothaire should have his choice, with the title of Emperor. About mid June, 842, the three brothers met on an island of the Saone, near Chalons, where they began to discuss the questions which divided them; but it was not till more than a year after, in August, 843, that assembling all three of them, with their umpires, at Verdun, they at last came to an agreement about the partition of the Frankish empire, save the three countries which it had been beforehand agreed to except. Louis kept all the provinces of Germany of which he was already in possession, and received besides, on the left bank of the Rhine, the towns of Mayence, Worms, and Spire, with the territory appertaining to them. Lothaire, for his part, had the eastern belt of Gaul, bounded on one side by the Rhine and the Alps, on the other by the courses of the Meuse, the Saone, and the Rhone, starting from the confluence of the two latter rivers, and, further, the country comprised between the Meuse and the Scheldt, together with certain countships lying to the west of that river. To Charles fell all the rest of Gaul: Vasconia or Biscaye, Septimania, the marches of Spain, beyond the Pyrenees, and the other countries of Southern Gaul which had enjoyed hitherto, under the title of the Kingdom of Aquitaine, a special government subordinated to the general government of the empire, but distinct from it, lost this last remnant of their Gallo-Roman nationality, and became integral portions of Frankish Gaul, which fell by partition to Charles the Bald, and formed one and the same kingdom under one and the same king.
Thus fell through and disappeared, in 843, by virtue of the treaty of Verdun, the second of Charlemagne’s grand designs, the resuscitation of the Roman empire by means of the Frankish and Christian masters of Gaul. The name of emperor still retained a certain value in the minds of the people, and still remained an object of ambition to princes; but the empire was completely abolished, and in its stead sprang up three kingdoms, independent one of another, without any necessary connection or relation. One of the three was thenceforth France.
