The city was frequently assailed by the Picts and Scots, and after the arrival of the Saxons it suffered considerably from the many wars that arose between the Britons and their new allies, as well as in the struggle for supremacy during the establishment of the several kingdoms of the Octarchy, and other minor wars. Early in the seventh century Eboracum underwent a change. By the Saxons the city was called Euro wic, Euore wic, and Eofor wic, which by Leland is supposed to have been borrowed from its situation on the river Eure, now known as the Ouse; but by what process these titles came to be contracted into its present name of York seems rather difficult to account. However, under the name of Eoforwic, the city flourished as the capital of the Bretwaldas early in the seventh century. Consequent on the conversion of Edwin, King of Northumbria, to Christianity, resulting from his marriage to Ethelburga, daughter of King Ethelbert of Kent, the city was erected in 624 into an archiepiscopal see, over which Paulinus, the confessor of the Queen, was made primate. In addition to this, Edwin had constituted the city as the metropolitan of his kingdom. Edwin's work upon the church, which he dedicated to St. Peter, and the missionary work of Paulinus, were suddenly suspended by an attack of the Britons under Cadwallo in 633. Edwin was killed, whilst Ethelburga escaped into Kent with Paulinus. The church in the meantime was allowed to decay until it was restored by Oswald, successor to Edwin. He managed to regain possession of his kingdom after a sanguinary conflict with Cadwallo, who, with the chief officers, was killed during the fight. [Illustration: YORK BOOTHAM BAR]
