'ealdorman' of his people. The wealth of the monasteries and the success of Anglo-Saxon society attracted the attention of people from mainland Europe, mostly Danes and Norwegians. Because of the plundering raids that followed, the raiders attracted the name Viking – from the Old Norse víkingr meaning an expedition – which soon became used for the raiding activity or piracy reported in western Europe. In 793, Lindisfarne was raided and while this was not the first raid of its type it was the most prominent. In 794, Jarrow, the monastery where Bede wrote, was attacked; in 795 Iona was attacked; and in 804 the nunnery at Lyminge Kent was granted refuge inside the walls of Canterbury. Sometime around 800, a Reeve from Portland in Wessex was killed when he mistook some raiders for ordinary traders. Viking raids continued until in 850, then the Chronicle says: "The heathen for the first time remained over the winter". The fleet does not appear to have stayed long in England, but it started a trend which others subsequently followed. In particular, the army which arrived in 865 remained over many winters, and part of it later settled what became known as the Danelaw. This was the "Great Army", a term used by the Chronicle in England and by Adrevald of Fleury on the Continent. The invaders were able to exploit the feuds between and within the various kingdoms and to appoint puppet kings, such as Ceolwulf in Mercia in 873 and perhaps others in Northumbria in 867 and East Anglia in 870. The third phase was an era of settlement; however, the "Great Army" went wherever it could find the richest pickings, crossing the English Channel when faced with resolute opposition, as in England in 878, or with famine, as on the Continent in 892. By this stage, the Vikings were assuming ever increasing importance as catalysts of social and political change. They constituted the common enemy, making the English more conscious of a national identity which overrode deeper distinctions; they could be perceived as an instrument of divine punishment for the people's sins, raising awareness of a collective Christian identity; and by 'conquering' the kingdoms of the East Angles, the Northumbrians and the Mercians, they created a vacuum in the leadership of the English people. Danish settlement continued in Mercia in 877 and East Anglia in 879—80 and 896. The rest of the
