NORSE EXPLORATION AND TRADE REACHED ITS PEAK BETWEEN 793 AND 1066 A.D. DURING THE VIKING AGE. VIKINGS WERE KNOWN FOR THEIR SEAMANSHIP, AND THE VIKING-ERA LONGSHIP WAS AN ENGINEERING MARVEL OF ITS DAY. IT WAS QUICK, NARROW, AND LIGHT, DARTING THROUGH SHALLOW OR DEEP WATER, POWERED BY OAR OR SAIL. FROM SCANDINAVIA, VIKINGS SAILED THE RIVERS OF EUROPE AND THE OCEANS EAST AND WEST FROM THE BALTIC TO BYZANTIUM. THEY SETTLED IN GREENLAND, ICELAND, VINLAND IN NORTH AMERICA, AND ACROSS EUROPE, LEAVING THEIR MARK ON EUROPEAN HISTORY.
