The First World War, also known as World War I, began in 1914 and lasted until 1918. It was primarily a conflict between the Allies (including France, the UK, Russia, and later the USA) and the Central Powers (Germany, Austria-Hungary, and the Ottoman Empire). The war was triggered by the assassination of Archduke Franz Ferdinand of Austria-Hungary. The war was fought mainly in Europe, with significant battles such as the Battle of the Somme and Verdun. The war led to the collapse of several empires, including the Russian, Ottoman, German, and Austro-Hungarian empires. The Treaty of Versailles, signed in 1919, officially ended the war and imposed heavy reparations on Germany. The impact of World War I influenced the course of the 20th century, setting the stage for World War II.
