 This army focused not on raiding, but on conquering and settling in Anglo-Saxon Britain, being composed of small bands that were already in Britain and Ireland that worked together for a period of time to accomplish their goals.The Vikings were also able to establish an extended period of economic and political rule of much of Ireland, England, and Scotland during the Norse Ivarr Dynasty that started in the late 9th century and lasted until 1094.In Ireland, coastal fortifications known as longphorts were established in many places after initial raidings, and they developed into trading posts and settlements over time.
