Question

Austria-Hungary, Bulgaria, Germany, and the Ottoman Empire became known as

Answer 1

Answers:

• Austria-Hungary, Bulgaria, Germany, and the Ottoman Empire became known as :  the Central Powers.
• The Western Front was characterized by  trench warfare that kept both sides in virtually the same positions for four years.
• The Schlieffen Plan was  Germany’s plan for a two-front war with Russia and France, which had formed a military alliance.

Allow me to add a bit of explanation about the last item, the Schlieffen Plan.  

The military plans laid before World War I presupposed a major war between the countries which were tied together with alliances.  Because the Triple Entente had Britain, France and Russia as allies, Germany thought if a war began it would need to fight on two fronts -- west and east.  So German Field Marshall Alfred von Schlieffen drew up war plans that said attack France first, quickly, and then hold that territory while deploying forces to contend with Russia in the east.   So when Germany declared war on Russia in 1914, the first thing it did was to march through Belgium to go and attack France.  Thus the war spread and became instantly a more global conflict.
