The Viking Age was ignited by the art of building seaworthy sailing ships and the skills to sail them on the open sea. The growth in seafaring, trade, piracy, and exploration that began to gather momentum during the 8th century CE was not limited to Europe's northern seas, however. Ships, laden with cargo and with seafarers who met foreign cultures, created unexpected connections between people from the Arctic Circle to the oceans south of the equator.

Travel accounts have handed down glimpses of these voyages to the present day. However, it is archaeological discoveries in particular which uncover the story of Viking-Age seafaring and voyages of exploration. The World in the Viking Age reveals a global history concerning ships, people and objects on the move. It is a story that challenges entrenched ideas about the past and present, and the skills and opportunities of previous generations.
