In the period between c. 870 and 914, the Vikings appear to have directed their activities in Britain and there was a relative peace in Ireland. The following 25 years beginning in 914 AD were perhaps a highpoint of Viking agression. More permanent Viking settlement began in this period. Initially the Irish were unable to counter these threats, and Niall Glundub, the Cenel nEogain king of Tara, was killed in battle at Dublin in 919. Yet the threat gradually receded by 940's and the Viking rulers were drawn into the Irish political order, so that their military power usually served Irish political ends.

By the middle of the tenth century Norse and Danish Viking coastal settlements and trading ports had been established at Dublin, Wexford, Waterford, Cork and Limerick. These Viking trading towns and their populations were gradually absorbed into the social and political system that surrounded them. The annals frequently make reference to Irish intermarriages and military alliances with the Vikings, as echoed in the famous Battle of Clontarf in 1014 AD with Viking constituents on both sides. By the late 10th century the 'Foreigners' in Dublin [and elsewhere] were not seen as an enemy to be driven back into the sea but as a potential source of wealth and tribute for the Irish chieftains. Claimants to the High Kingship of Ireland soon came to understand that their power would often be gauged by their ability to control the important port of Dublin.

Although the early Vikings, or 'Ostmen', were well-known for their raids on the Irish and the Irish Church, their contributions to Ireland were to have a greater positive impact, This included the establishment of Ireland's first towns, the expansion of its seafaring trade, and the influence on its art.

Within the Irish political scene the power control of the kings of Tara (Ireland) alternated between the Northern and Southern Ui Niaill (Neill) clans. In the 9th century Maelsechnaill (I) of Clann Cholmain began to make forays into Munster attempting to strengthen the Southern Ui Niaill influence, creating enemies rather than allies of the Munstermen. This policy led to a disastrous reaction from Munster by the end of the 10th century, viz. Brian Borumha.
