With World War I having effectively settled into a stalemate in Europe, the Allies attempted to score a victory against the Ottoman Empire, which entered the conflict on the side of the Central Powers in late After a failed attack on the Dardanelles the strait linking the Sea of Marmara with the Aegean Sea , Allied forces led by Britain launched a large-scale land invasion of the Gallipoli Peninsula in April The invasion also proved a dismal failure, and in January Allied forces staged a full retreat from the shores of the peninsula after suffering , casualties.
British-led forces also combated the Ottoman Turks in Egypt and Mesopotamia , while in northern Italy, Austrian and Italian troops faced off in a series of 12 battles along the Isonzo River, located at the border between the two nations.
British and French—and later, American—troops arrived in the region, and the Allies began to take back the Italian Front. The biggest naval engagement of World War I, the Battle of Jutland May left British naval superiority on the North Sea intact, and Germany would make no further attempts to break an Allied naval blockade for the remainder of the war.
World War I was the first major conflict to harness the power of planes. At the dawn of World War I, aviation was a relatively new field; the Wright brothers took their first sustained flight just eleven years before, in Aircraft were initially used primarily for reconnaissance missions. During the First Battle of the Marne, information passed from pilots allowed the allies to exploit weak spots in the German lines, helping the Allies to push Germany out of France.
The first machine guns were successfully mounted on planes in June of in the United States, but were imperfect; if timed incorrectly, a bullet could easily fell the propeller of the plane it came from. The Morane-Saulnier L, a French plane, provided a solution: The propeller was armored with deflector wedges that prevented bullets from hitting it. The British Bristol Type 22 was another popular model used for both reconnaissance work and as a fighter plane.
Dutch inventor Anthony Fokker improved upon the French deflector system in Though his most popular plane during WWI was the single-seat Fokker Eindecker, Fokker created over 40 kinds of airplanes for the Germans. On April 1, , the British created the Royal Air Force, or RAF, the first air force to be a separate military branch independent from the navy or army.
With Germany able to build up its strength on the Western Front after the armistice with Russia, Allied troops struggled to hold off another German offensive until promised reinforcements from the United States were able to arrive. On July 15, , German troops launched what would become the last German offensive of the war, attacking French forces joined by 85, American troops as well as some of the British Expeditionary Force in the Second Battle of the Marne.
The Allies successfully pushed back the German offensive and launched their own counteroffensive just three days later. The Second Battle of the Marne turned the tide of war decisively towards the Allies, who were able to regain much of France and Belgium in the months that followed.
Despite the Turkish victory at Gallipoli, later defeats by invading forces and an Arab revolt had combined to destroy the Ottoman economy and devastate its land, and the Turks signed a treaty with the Allies in late October Austria-Hungary, dissolving from within due to growing nationalist movements among its diverse population, reached an armistice on November 4.
Facing dwindling resources on the battlefield, discontent on the homefront and the surrender of its allies, Germany was finally forced to seek an armistice on November 11, , ending World War I. At the Paris Peace Conference in , Allied leaders stated their desire to build a post-war world that would safeguard itself against future conflicts of such devastating scale.
It is fitting at the close of the 20th century that some thought be given to the initial calamity that set the century upon its destructive course. The First World War by. World War I began in , after the assassination of Archduke Franz and destruction due to new military technologies and the horrors of trench warfare. In the first battle of World War I, the Germans assaulted the heavily.
As the years passed, hatred of the Versailles treaty and its authors settled into a smoldering resentment in Germany that would, two decades later, be counted among the causes of World War II. World War I took the lives of more than 9 million soldiers; 21 million more were wounded. Civilian casualties caused indirectly by the war numbered close to 10 million. The two nations most affected were Germany and France, each of which sent some 80 percent of their male populations between the ages of 15 and 49 into battle. The political disruption surrounding World War I also contributed to the fall of four venerable imperial dynasties: Germany, Austria-Hungary, Russia and Turkey.
World War I brought about massive social upheaval, as millions of women entered the workforce to support men who went to war and to replace those who never came back. The severe effects that chemical weapons such as mustard gas and phosgene had on soldiers and civilians during World War I galvanized public and military attitudes against their continued use. The Geneva Convention agreements, signed in , restricted the use of chemical and biological agents in warfare and remains in effect today.

Just about everything that happened in the remainder of the century was in one way or another a result of World War I, including the Bolshevik Revolution in Russia, World War II, the Holocaust, and the development of the atomic bomb. It was the first war to use airplanes, tanks, long range artillery, submarines, and poison gas. It left at least 7 million men permanently disabled. World War I probably had more far-reaching consequences than any other proceeding war.
Politically, it resulted in the downfall of four monarchies--in Russia in , in Austria-Hungary and Germany in , and in Turkey in It contributed to the Bolshevik rise to power in Russia in and the triumph of fascism in Italy in It ignited colonial revolts in the Middle East and in Southeast Asia. Economically, the war severely disrupted the European economies and allowed the United States to become the world's leading creditor and industrial power.
The war also brought vast social consequences, including the mass murder of Armenians in Turkey and an influenza epidemic that killed over 25 million people worldwide.
