The Viking Invasions were a series of raids and settlements by Norse explorers from Scandinavia, primarily during the late 8th to early 11th centuries. These seafaring warriors targeted various regions, including the British Isles, parts of France, and even Russia. Their longships allowed them to navigate rivers and coastal waters, facilitating their surprise attacks on monasteries and towns. The invasions led to significant cultural exchanges and the establishment of Viking settlements, such as Dublin in Ireland and York in England. Over time, the Vikings transitioned from raiders to traders and settlers, influencing the regions they occupied and contributing to the development of medieval Europe.
