Explain why germany's location in europe contributed to it's being involved in a two front war

I presume your question is in reference to The Great War, which we now call World War I.

The days leading up to the Great War (World War I) were full of military buildup, military planning, and countries lining up with one another in alliance systems.  The Triple Entente had Britain, France and Russia as allies.  In between those countries were the members of the Triple Alliance:  Germany, Austria-Hungary, and Italy, with Germany as the leading power in that group.  

Because of the alliance system, Germany assumed that if a war began, it would need to fight on two fronts -- west and east. Germany assumed it would be fighting against both France (on its western border) and Russia (on its eastern border) if war broke out.

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.

In 1914, when Russia mobilized troops to come to the aid of Serbia against Austria-Hungary in 1914 (after the assassination of Austria's archduke by Serbian radicals), Germany declared war on Russia.  And when Germany went to war, the first thing it did was to march through Belgium to go and attack France.  Up to that point France had not had involvement in the conflicts that had begun in the Balkans.  Thus the war spread and quickly became a more global conflict.

the assassination of president lincoln was just one part of a larger plot to decapitate the federal government of the u.s. after the civil war. the first reaction to lincoln’s death was disbelief. then it quickly changed to grief. abraham lincoln’s death created an outpouring of grief from citizens in both the north and the south.

explanation:

lincoln was the first u.s. president to be assassinated. president abraham lincoln, america’s civil war leader, was assassinated just five days after confederate general robert e. lee surrendered his army at appomattox court house, ending the four-year war between the states. on the evening of april 14, 1865, lincoln was attending a performance of our american cousin at ford’s theatre in washington, d.c. john wilkes booth – a 26-year old actor, confederate sympathizer, and white supremacist – slipped into the presidential box and shot lincoln in the head. john wilkes booth and his conspirators had initially planned to kidnap lincoln to save the confederate states. but as the confederacy faltered, booth’s thoughts turned to murder. booth may have decided to act on his hatred after lincoln endorsed giving the right to vote to african-american men who had served in the union army.
