Introduction about world war one
World War I is infamous for the protracted stalemate of trench warfare along the Western Front, embodied within a system of opposing manned trenches and fortifications (separated by a "No man's land") running from the North Sea to the border of Switzerland. Hostilities were also prosecuted, however, by more dynamic invasion and Battle, by fighting at sea and - for the first time - in and out from the air. Also, there were some battles that foreshadowed the rapid movement of WWII, take for example the Battle of St. Mihel in 1918. Here, within a matter of one day, American troops, supported by tanks, airplanes, and artillery, advanced over 20 miles, clearing a salient that had been a thorn in the side of the French army since 1914. More than 9 million soldiers died on the various battlefields, and nearly that many more in the participating countries' home fronts on account of food shortages and genocide committed under the cover of various civil wars and internal conflicts. In World War I, only some 5% of the casualties (directly caused by the war) were civilian - in World War II, this figure approached 50%.
Ultimately, World War I Created a decisive break with the old world order that had emerged after the Napoleonic Wars, as modified by the mid-19th century National revolutions, the processes of European national unification and European colonialism. Three European land empires were shattered and subsequently dismembered to varying degrees: the German, the Austro-Hungarian and the Russian. In the Balkans and the Middle East, the Ottoman Empire experienced the same fate.
