Causes of World War 1

One cause of WWI was nationalism. It caused Germany and Italy to move a part their states, but strong nationalist movements and revolutions led to the unification of in 1861 and that of Germany in 1871. Another cause was that the Franco-Prussian War of Germany in 1870-1871 was that France was left seething over the loss of Alsace-Lorraine to Germany and Revanche was a major goal of the French.

A second reason was imperialism. Great Britain, France and Germany had to get foreign markets after the increase in manufacturing caused by the Industrial Revolution. Those countries competed for economic expansion in Africa. Britain and France resolved their differences in Africa. Crises was foreshadowing the war involved the conflict of Germany against Britain and France in North Africa.
