Which is the best example of nationalism causing tensions in Europe?

A. Germany worried about economic rivalry with Russia.
B. Britain built the world’s most respected navy.
C. France was bitter about losing Alsace and Lorraine in the Franco-Prussian War.
D. Competition for colonies brought France and Germany to the brink of war in Morocco

Answer 1

C. France being bitter about losing Alsace and Lorraine in the Franco-Prussian War is the best example of nationalism causing tensions in Europe. France's loss of territory to Germany in the Franco-Prussian War led to a strong desire for revenge and a determination to regain the lost territory, which created tension between France and Germany. This nationalist sentiment contributed to the outbreak of World War I.
