Summary

By the mid-9th century, Ireland, Scotland, and England had become major targets for Viking settlement and raids. Vikings gained control of key territories in Scotland, including the Northern Isles, Hebrides, and mainland areas. In Ireland, they established trading towns that served as bases for raids. When Frankia’s defences were strengthened, Viking forces turned their attention to England, where they found ample opportunities for conquest and plunder.

By the mid-9th century, Ireland, Scotland, and England faced increased Viking presence. In Scotland, Vikings established dominance over the Northern Isles (Shetland and Orkneys) and the Hebrides, along with significant control over mainland Scotland.

Within Ireland, Vikings established trading towns along the coast, including Dublin, Waterford, Wexford, Wicklow, and Limerick. These settlements served as bases for raids within Ireland and across the Irish Sea to England.

However, King Charles the Bald’s efforts to fortify West Frankia in 862 prompted Viking forces to shift their focus towards England. As Frankia’s defences strengthened, the Vikings found greater opportunities for conquest and plunder in England.

By the mid-ninth century, Ireland, Scotland and England had become major targets for Viking settlement with those raids. Vikings gained control of the Northern Isles of Scotland (Shetland and the Orkneys), the Hebrides and much of mainland Scotland. They founded Ireland’s first trading towns: Dublin, Waterford, Wexford, Wicklow and Limerick, and used their base on the Irish coast to launch attacks within Ireland and across the Irish Sea to England. When King Charles the Bald began defending West Frankia more energetically in 862, fortifying towns, abbeys, rivers and coastal areas, Viking forces concentrated more on England than Frankia.
