A longship is a type of ship used by the Vikings from around the 8th to the 11th centuries. These vessels are characterized by their long, narrow hulls, shallow drafts, and symmetrical ends, allowing them to navigate both open seas and shallow rivers. Longships were primarily used for exploration, trade, and warfare. The design of longships enabled them to be fast and agile, making them effective for raiding and transporting troops. They were often powered by both sails and oars, allowing for versatility in different weather conditions. Longships played a crucial role in the expansion of Norse culture across Europe.
