The sail was invented long ago and provided a way to harness the wind to power ships. Gas turbine engines came along in modern times and is used today to power ships.
The main power source for a longship was its sails, which harnessed wind to propel the vessel across the water. In addition to sails, longships were also equipped with oars, allowing them to maneuver effectively in shallow waters or during calms when wind was insufficient. This combination of sail and oar made longships versatile and capable of swift travel across various marine environments.

Viking society was primarily divided into three main groups: the nobility, the freemen, and the thralls. The nobility, or jarls, held political power and land, often leading raids and trade expeditions. Freemen, or karls, were common people who could own land and participate in local governance, while thralls were enslaved individuals, often captured in raids, who worked for the other two groups. This stratification influenced social dynamics and economic activities within Viking communities.
