Explanation of Alliances
The war began in 1914 after the assassination of Archduke Franz Ferdinand of Austria, which led to Austria-Hungary declaring war on Serbia. The complex system of alliances that had developed over the previous decades rapidly escalated the conflict. Russia mobilized in defense of Serbia, prompting Germany to declare war on Russia and subsequently on Russia’s ally, France. The United Kingdom entered the war after Germany invaded Belgium, a neutral country.
Italy’s entry on the side of the Allies was influenced by promises of territorial gains, and the United States joined the war later, primarily due to unrestricted submarine warfare by Germany and the Zimmerman Telegram, which sought to incite Mexico against the U.S.
The war was characterized by trench warfare, new military technologies, and a high number of casualties, ultimately leading to the defeat of the Central Powers and the signing of the Treaty of Versailles in 1919. The war significantly altered national borders and set the stage for future conflicts, including World War II.
