The deaths of British merchant sailors and the seeming invulnerability of U-boats led to the development of depth charges , hydrophones passive sonar, , blimps, hunter-killer submarines HMS R-1, , forward-throwing anti-submarine weapons, and dipping hydrophones the latter two abandoned in To extend their operations, the Germans proposed supply submarines Most of these would be forgotten in the interwar period until World War II revived the need.
Fixed-wing aircraft were first used militarily by the Italians in Libya in October during the Italo-Turkish War for reconnaissance, soon followed by the dropping of grenades and aerial photography the next year. By , their military utility was obvious. They were initially used for reconnaissance and ground attack. To shoot down enemy planes, anti-aircraft guns and fighter aircraft were developed. Strategic bombers were created, principally by the Germans and British, though the former used Zeppelins as well.
Towards the end of the conflict, aircraft carriers were used for the first time, with HMS Furious launching Sopwith Camels in a raid to destroy the Zeppelin hangars at Tondern in Recognized for their value as observation platforms, balloons were important targets for enemy aircraft. To defend them against air attack, they were heavily protected by antiaircraft guns and patrolled by friendly aircraft; to attack them, unusual weapons such as air-to-air rockets were even tried.
Thus, the reconnaissance value of blimps and balloons contributed to the development of air-to-air combat between all types of aircraft and to the trench stalemate, because it was impossible to move large numbers of troops undetected. The Germans conducted air raids on England during and with airships, hoping to damage British morale and cause aircraft to be diverted from the front lines. The resulting panic led to the diversion of several squadrons of fighters from France.
Almost the whole of Europe and its colonial empires mobilized to wage World War I, directing almost all aspects of life including industry, finance, labor, and food production toward military purposes. Total war includes all civilian-associated resources and infrastructure as legitimate military targets, mobilizes all societal resources to fight the war, and gives priority to warfare over non-combatant needs.
In a total war, to an extent inapplicable to other conflicts, the differentiation between combatants and non-combatants diminishes and even sometimes vanishes entirely as opposing sides consider nearly every human resource, even that of non-combatants, as part of the war effort.
Actions that characterize the postth century concept of total war include: blockade and sieging of population centers, as with the Allied blockade of Germany; commerce-raiding tonnage war, and unrestricted submarine warfare, as with privateering and the German U-Boat campaigns. Almost the whole of Europe and its colonial empires mobilized to wage World War I.
Young men were removed from production jobs to serve in military roles and were replaced by women. Rationing occurred on the home fronts. Conscription was common in most European countries but controversial in English-speaking countries. About , lost their lives. Though most deaths were young unmarried men, , wives lost husbands and , children lost fathers. In the United States, conscription began in and was generally well-received, with a few pockets of opposition in isolated rural areas.
Bulgaria went so far as to mobilize a quarter of its population or , people, a greater share than any other country during the war. In Britain, government propaganda posters were used to divert all attention to the war on the home front. They influenced public opinion about what to eat and what occupations to pursue, and changed the attitude toward the war effort to one of support. Even the Music Hall was used as propaganda, with songs aimed at recruitment.
After the failure of the Battle of Neuve Chapelle, the large British offensive in March , the British Commander-in-Chief Field Marshal John French blamed the lack of progress on insufficient and poor-quality artillery shells. This led to the Shell Crisis of , which brought down both the Liberal government and Premiership of H. He formed a new coalition government dominated by liberals and appointed David Lloyd George as Minister of Munitions.
It was a recognition that the whole economy would have to be geared for war if the Allies were to prevail on the Western Front. As young men left the farms for the front, domestic food production in Britain and Germany fell. In Britain the response was to import more food, despite the German introduction of unrestricted submarine warfare, and to introduce rationing.
All of the powers in expected a short war; none had made any economic preparations for a long war, such as stockpiling food or critical raw materials. The longer the war went on, the greater the advantages of the Allies, with their larger, deeper, more versatile economies and better access to global supplies.
As historians Broadberry and Harrison conclude, once stalemate set in late in But they were highly onerous, arguably unjustifiably so, and were deeply unpopular in Germany. Hitler seized on this growing resentment and promised to "undo this injustice and tear up this treaty and restore Germany to its old greatness".
In fact, the payments demanded were so large that Germany was able to repay the final installment of interest on this debt only on October 3, The sequence of events for World War I began in with Austria-Hungary declaring war on Serbia on 28 July in a bid to reassert its authority as a Balkan power. With war breaking out between Austria-Hungary on one side and Serbia on the other, Europe quickly fell back to the alliances nations had formed.
Austria-Hungary and Germany were allies. Serbia was allied with Russia; as was France. Russia aided Serbia and attacked Austria. So Austria-Hungary was fighting in two fronts with Serbia and with Russia and consequently lost on both fronts.
In a bid to aid Austria-Hungary against Russia, and fearing an attack from France, Germany mobilized its army and attacked France. The war that broke out in was a war for the European balance of power. Poland refused to agree to German demands, and on 1 September overwhelming German forces launched the Polish campaign and defeated her in three weeks. Russia also invaded eastern Poland. Poland thus got divided into two parts.
In March Britain and France had guaranteed Polish sovereignty, and in honor of that pledge first demanded that German forces withdraw, and then on 3 September declared war on Germany. America was committed by the Neutrality Acts of and of non-intervention in overseas conflicts.
The entry of the USA signaled a change in the political balance of the war of great significance. German forces in Stalingrad surrendered in January and by May Italian and German forces finally surrendered in Tunisia, enabling the Allies to mount the invasion of Sicily and then Italy.
Italy sued for an armistice in September American economic might and political interests helped to bind together the different fronts of conflict, while America's worldwide system of supply and logistics provided the sinews of war necessary to complete the defeat of the aggressor states.
A major intelligence deception operation and declining air power weakened the German response and by September German forces had been driven from France. Many of the weapons that dominate military operations today were developed during World War I, including the machine gun, the tank and specialized combat aircraft.

Militarism, Imperialism, nationalism and alliance system. Political and economic instability in Germany. Over 60 million people died in World War II. Estimated deaths range from million. German Nazis committed genocide against Jews and Romanis, people with disabilities, Poles, homosexuals, Jehovah's witnesses and Afro-Germans. Because mighty Russia supported Serbia, Austria-Hungary waited to declare war until its leaders received assurance from German leader Kaiser Wilhelm II that Germany would support their cause.
The Dual Monarchy of Austria-Hungary then sent an ultimatum to Serbia, with such harsh terms as to make it almost impossible to accept.
Convinced that Austria-Hungary was readying for war, the Serbian government ordered the Serbian army to mobilize and appealed to Russia for assistance. According to an aggressive military strategy known as the Schlieffen Plan named for its mastermind, German Field Marshal Alfred von Schlieffen , Germany began fighting World War I on two fronts, invading France through neutral Belgium in the west and confronting Russia in the east.
On August 4, , German troops crossed the border into Belgium. In the first battle of World War I, the Germans assaulted the heavily fortified city of Liege , using the most powerful weapons in their arsenal—enormous siege cannons—to capture the city by August The Germans left death and destruction in their wake as they advanced through Belgium toward France, shooting civilians and executing a Belgian priest they had accused of inciting civilian resistance.
In the First Battle of the Marne , fought from September , , French and British forces confronted the invading Germany army, which had by then penetrated deep into northeastern France, within 30 miles of Paris. The Allied troops checked the German advance and mounted a successful counterattack, driving the Germans back to north of the Aisne River. The defeat meant the end of German plans for a quick victory in France. Both sides dug into trenches , and the Western Front was the setting for a hellish war of attrition that would last more than three years.
Particularly long and costly battles in this campaign were fought at Verdun February-December and the Battle of the Somme July-November German and French troops suffered close to a million casualties in the Battle of Verdun alone. In the latter poem, McCrae writes from the perspective of the fallen soldiers:.
To you from failing hands we throw The torch; be yours to hold it high. If ye break faith with us who die We shall not sleep, though poppies grow In Flanders fields. Visual artists like Otto Dix of Germany and British painters Wyndham Lewis, Paul Nash and David Bomberg used their firsthand experience as soldiers in World War I to create their art, capturing the anguish of trench warfare and exploring the themes of technology, violence and landscapes decimated by war.
This increased hostility was directed toward the imperial regime of Czar Nicholas II and his unpopular German-born wife, Alexandra. Russia reached an armistice with the Central Powers in early December , freeing German troops to face the remaining Allies on the Western Front. At the outbreak of fighting in , the United States remained on the sidelines of World War I, adopting the policy of neutrality favored by President Woodrow Wilson while continuing to engage in commerce and shipping with European countries on both sides of the conflict.
In , Germany declared the waters surrounding the British Isles to be a war zone, and German U-boats sunk several commercial and passenger vessels, including some U. Widespread protest over the sinking by U-boat of the British ocean liner Lusitania —traveling from New York to Liverpool, England with hundreds of American passengers onboard—in May helped turn the tide of American public opinion against Germany.
Germany sunk four more U. 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 destroy 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.
