What was one of the causes of tensions in europe that led to world war i? the nations in eastern europe wanted to unite as a single nation under the ottoman empire. germany, austria-hungary, and russia promised to send military support if a war broke out in europe. france, germany, and other nations were competing for overseas territory in africa and other places. britain cut off germany’s supply ships, and the german people were slowly starving.

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

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.
