Entangling alliances triggered by the assassination.  Austria-Hungary declared war on Serbia because of the assassination.  Serbia was allied with Russia, so Russia was dragged into the war.  Germany mobilized to attack Russia, but Russia was allied with France so France came to Russia's defense.  Germany and France had been at war before and had plans for invading each other.  France's entry into the war led Germany to use one of their old plans for invading France which required them to march through Belgium.  Britain was allied with Belgium and had pledged to help Belgium in the event of an attack by Germany, so Britain was pulled in on the side of the French and Russians.  Since Britain was involved, that meant all of her colonies were involved as well.  \n\nThe book The Guns of August has lots of details on the causes of the war.\n\nAlso, check out the Wikipedia article at http://en.wikipedia.org/wiki/Causes_of_World_War_I

The Army is the branch of the United States armed forces that has primary responsibility for land-based military operations. As of fiscal year 2004 (FY04), it consisted of 485,500 soldiers (including 71,400 women) on active duty and 591,000 in reserve (325,000 in the Army National Guard (ARNG) and 246,000 in the United States Army Reserve (USAR)). The Continental Army was formed on June 14, 1775, before the establishment of the United States, to meet the demands of the American Revolutionary War. Congress created the United States Army on June 3, 1784 after the end of the American Revolutionary War, to replace the disbanded Continental Army. However, the US Army considers itself to be an evolution of the Continental Army, and thus dates its inception from the origins of the Continental Army.

Killing of Archduke was a trigger moment, I think.\nThe real cause was that Germany started rising very fast and it has discovered that it was left behind by countries like British Empire, US and France. True, they had big economies and vast colonial territories (like Britain and France)in Africa and Asia, plus European map consisted of unsolved puzzles.\nThe steadfast growing of German economy and its advance in military technologies made it possible to challenge the world leaders of that time and finish first the Austria-Hungary Empire.\nUltimately, the cause for WW 1 were nonnegotiable contradictions within the Great Powers of that time.
