The correct answer is $1914-1918$.<br /><br />The First World War, also known as World War I, took place from 1914 to 1918. It was a global conflict that involved many of the world's major powers, including the Allied Powers (such as France, Russia, and the United Kingdom) and the Central Powers (such as Germany, Austria-Hungary, and the Ottoman Empire).<br /><br />The war began in July 1914, following the assassination of Archduke Franz Ferdinand of Austria by a Serbian nationalist. This event triggered a series of diplomatic and military actions that led to the outbreak of the war. The conflict lasted for four years, with major battles taking place on the Western Front (in France and Belgium) and the Eastern Front (in Russia and the Balkans).<br /><br />The war ended in November 1918, with the signing of the Armistice on November 11, 1918. The Treaty of Versailles, signed in June 1919, formally ended the war and imposed heavy penalties on Germany, which contributed to the rise of Nazism and the outbreak of World War II in the 1930s.<br /><br />The other options provided are incorrect:<br /><br />- $1240-1480$ refers to the Middle Ages, a period that predates the First World War by several centuries.<br />- $1812-1815$ refers to the War of 1812, a conflict between the United States and the United Kingdom that took place during the early 19th century.<br />- $1939-1945$ refers to the Second World War, which followed the First World War by two decades.
