The Christian empire  of the West divided into three kingdoms, those of Lothaire, Louis and Charles the Bald since the Treaty of Verdun in 843 is the subject of several threats: Lothaire undergoes Muslim attacks that go so far as to threaten Rome in 846. The Muslims are content to plunder the Basilica of St. Peter, they take many cities in Italy. It is also threatened by the Vikings who are multiplying incursions into Europe including Muslim Spain and the kingdoms of Louis and Charles.
During this generation, Louis seeks to invade the territory of Charles facing new Viking threats. With the support of the clergy and these vassals, Charles succeeds in preserving his territories. The advantages granted to the vassals initialize the feudal power which will be of setting throughout the Middle Ages. The kingdom of Lothaire is shared between his three sons at his death in 855.
This revival is accompanied by a new advance of Christianity on pagan lands. Photios emissaries carry the “good word” in the Slavic countries, which by opening themselves to Christianity participate in the extension of the role of Europe in the history of the world, thus enlarging the “valley of weeping”.
