For many generations, Norway, with its homely, rugged population engaged in trade, shipping, fishing, and agriculture, had stood outside the turmoil of world politics. Far off were the days when the Vikings had sallied forth to conquer or ravage a large part of the then-known world. The Hundred Years' War, the Thirty Years' War, the wars of William III and Marlborough, the Napoleonic convulsion, and later conflicts had left Norway―though separated from Denmark―unmoved and unscathed. A large proportion of the people had hitherto thought of neutrality and neutrality alone. A tiny army and a population with no desires except to live peaceably in their own mountainous and semi-Arctic country now fell victims to the new Germanaggression.
