Meanwhile on the Eastern Front the Germans advanced but not decisively.

After a brief German advance in 1914, the western front was stabilized and a long and brutal trench warfare started: it was a 'war of attrition' (the western front remained immovable).

The second front was the Eastern front in which the Russians fought against Germans and Austro-Hungarians. The two main scenarios were the Western front, where the Germans confronted Britain, France and, after 1917, the Americans. The conflict developed on several fronts in Europe, Africa, and Asia.Some of the major battles during the war included the First Battle of the Marne, Battle of the Somme, Battle of Tannenberg, Battle of Gallipoli, and the Battle of Verdun.Britain declared war on Germany because of its invasion of neutral Belgium - Britain had agreements to protect both Belgium and France.

Germany then declared war on Russia because Germany had an alliance with Austria-Hungary.Russia got involved as it had an alliance with Serbia.Because its leader had been shot, Austria-Hungary declared war on Serbia. He was killed by a Serbian person, who thought that Serbia should control Bosnia instead of Austria. Assassination of Archduke Franz Ferdinand: In June 1914, Archduke Franz Ferdinand, the heir to the throne of Austria-Hungary, was shot while he was visiting Sarajevo in Bosnia.Nationalism: Much of the origin of the war was based on the desire of the Slavic peoples in Bosnia and Herzegovina to no longer be part of Austria Hungary but instead be part of Serbia.This increase in militarism helped push the countries involved into war. Great Britain and Germany both greatly increased their navies in this time period. By 1914, Germany had the greatest increase in military buildup. Militarism: As the world entered the 20th century, an arms race had begun.The increasing competition and desire for greater empires led to an increase in the confrontation that helped push the world into World War I. Imperialism: Before World War I, Africa and parts of Asia were points of contention among the European countries because of their raw materials.Thus, there were two rival groups in Europe.įig: Alliances at the beginning of the War.The Triple Entente, which was made up of Britain, France, and Russia, concluded by 1907.The Triple Alliance-1882 linking Germany with Austria-Hungary and Italy.These treaties meant that if one country was attacked, allied countries were bound to defend them. Mutual Defense Alliances: Countries throughout Europe made mutual defence agreements.Germany was seen as a threat by the other powers and destabilized the international situation. The new international expansionist policy of Germany: In 1890 the new emperor of Germany, Wilhelm II, began an international policy that sought to turn his country into a world power.The war happened because of several different events that took place in the years building up to 1914. There was no single event that led to World War I. The main members of the Central Powers were Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria.The United States also fought on the side of the Allies after 1917. The main members of the Allied Powers were France, Russia, and Britain.WW I was fought between the Allied Powers and the Central Powers.

World War I (WW I), also known as the Great War, lasted from 28 July 1914 to 11 November 1918.
