World War One, also known as the Great War, thewartoendallwars, or the warofthenations, was a global conflict centered in Europe that began on July 28, 1914, and lasted until November 11, 1918
135 countries took part in World War One, with more than 15 million people losing their lives
The conflict involved nearly all of the biggest powers in the world and was focused around two alliances: the Allies and the Central Powers
Countries of the Allies included Russia, France, the British Empire, Italy, the United States, Japan, Romania, Serbia, Belgium, Greece, Portugal, and Montenegro
Countries of the Central Powers included Germany, Austria-Hungary, Turkey, and Bulgaria
World War One began on June 28, 1914, triggered by the assassination of Archduke Franz Ferdinand of Austria and his wife Sophie by a Bosnian revolutionary called Gavrilo Princip
One of the primary causes of World War One was a difference over foreign policy, with the assassination of Franz Ferdinand being the immediate trigger
Tensions over foreign policy between major world powers, a tangle of alliances, and territorial ambitions all contributed to the outbreak of World War One
The Bosnian crisis and the Moroccan crisis were events that heightened tensions and contributed to the outbreak of World War One
The United States entered World War One in 1917 after 128 Americans were killed by a German submarine, leading to President Woodrow Wilson declaring war to restore peace in Europe
Over 8 million soldiers died in World War One, with 21 million injured and a total of 65 milliontroops mobilized during the conflict
Chemical weapons, particularly mustard gas, were used for the first time in World War One
The Treaty of Versailles in 1919 officially ended World War One, requiring Germany to accept full responsibility for causing the war, make reparations, surrender territory, and limit its military
The League of Nations was established to prevent future wars, but the US Senate's refusal to join and the resentment in Germany and Japan led to their withdrawal from the League
World War One led to the collapse of empires, including the Russian Empire, the Ottoman Empire, the German Empire, and the Austro-Hungarian Empire
Interesting facts about World War One include the invention of plastic surgery, the establishment of blood banks, and the experiences of soldiers in the trenches
Before World War I, a significant arms race occurred among major European powers like Germany, France, and Britain, leading to competition to build up military capabilities including naval forces, armies, and weaponry
The arms race created insecurity and mistrust among nations involved, each seeking to maintain or enhance military superiority over others
Militarism was closely intertwined with alliance systems in Europe before the war, with formations like the Triple Entente (France, Russia, and Britain) and the Triple Alliance (Germany, Austria-Hungary, and Italy) creating a complex web of military commitments and obligations
Alliances were partly a response to militaristic policies and actions by rival powers, escalating tensions and making the outbreak of war more likely
Militarism influenced the development of military strategies and war plans that emphasized offensive operations and rapid mobilization, with military leaders eager to use their power to achieve political objectives
Militarism was closely linked with nationalism in Europe before World War I, with nationalistic fervor fueling public support for militaristic policies and aggressive actions by governments
Militarystrength and conquest were often seen as symbols of national pride and superiority, leading to a willingness to use force to assert dominance and expand territory
Overall, militarism fostered an atmosphere of competition, suspicion, and aggression among major European powers, making the outbreak of WorldWar I more likely as tensions escalated and diplomaticefforts to resolve conflicts failed
The assassination of Archduke Franz Ferdinand of Austria-Hungary in Sarajevo in 1914 triggered a chain reaction of events that led to war
Austria-Hungary, supported by Germany, issued an ultimatum to Serbia after the assassination, demanding harsh concessions
Serbia, backed by Russia, refused to comply completely, leading Austria-Hungary to declare war on Serbia
Russia's mobilization prompted Germany to declare war on Russia and its ally France, escalating the conflict
The Franco-German rivalry and the Schlieffen Plan:
Germany's military strategy, the Schlieffen Plan, aimed to quickly defeat France in a two-front war by invading France through Belgium
The plan was driven by fears of encirclement by France and Russia
Germany's alliance with Austria-Hungary and the expectation of Italian neutrality were crucial for the plan
Implementing the Schlieffen Plan in 1914 violated Belgian neutrality and drew Britain into the war, as Britain was committed to defending Belgian sovereignty through treaties
When Austria-Hungary declared war on Serbia in 1914, Russia began mobilizing its forces to support Serbia
When Austria-Hungary declared war on Serbia in 1914, Russia began mobilizing its forces to support Serbia
Germany, fearing a two-front war against Russia and France, issued a "blank check" of unconditional support to Austria-Hungary, emboldening Austria-Hungary to take a hardline stance against Serbia
Militarism in Europe in the 1800s and early 1900s was a significant force, with many governments strongly influenced, if not dominated, by military leaders, interests, and priorities
Generals and admirals sometimes acted as de facto government ministers, advising political leaders, influencing domestic policy, and demanding increases in defence and arms spending
The rising militarism in Europe led to an arms race, fostering new military technologies and increased defence spending
Militarism not only affected policy but also shaped culture, the media, and public opinion, with the press portraying military leaders as heroes and painting rival nations as aggressive
Militarism created an environment where war, rather than negotiation or diplomacy, was considered the best way of dealing with foreign rivals and settling international disputes
