Viking raids began in AD793 with small, unorganized attacks on monasteries in England. The raids grew in size and frequency as thousands of Vikings left Scandinavia to pillage other lands, traveling via rivers to trade in places like Istanbul and Baghdad. Norwegians sought new lands, settling in Scotland, Ireland, Iceland and Greenland while Danish Vikings focused on Ireland, Wales and eastern England. The Vikings looted treasures, slaves, food, gold and other goods. Monks recorded the attacks and described the widespread destruction, massacres, burnings, and theft wrought by the Vikings as well as the terror left among the remaining populations.
