What was one of the causes of tensions in europe that led world war 1?

 France, Germany, and other nations were competing for overseas territory in Africa and other places.

Explanation:

The days leading up to the Great War (World War I) were full of imperialistic competition overseas, as well as military buildup and military planning within Europe.  The countries of Europe began lining up with one another in alliance systems as well.    

The excessive competition between nations in seeking overseas territories in Africa and Asia was not only a part of the tension leading up to World War I.  The extension of European power into those other world regions also explain why it became a "world war."  When the war broke out, the European nations brought native peoples from their colonies to join in the war effort.
