"World War I (28 July 1914 – 11 November 1918)..."
The study of the global war that lasted from 1914 to 1918.
Causes of World War I: This topic delves into the various factors that contributed to the outbreak of World War I, including nationalism, imperialism, alliances, and militarism.
Assassination of Archduke Franz Ferdinand: The assassination of Archduke Franz Ferdinand of Austria-Hungary by Serbian nationalist Gavrilo Princip is widely considered the event that sparked the outbreak of World War I.
Trench Warfare: Trench warfare was a major element of World War I, in which soldiers on both sides dug elaborate networks of trenches to protect themselves from enemy fire.
Technology of World War I: World War I saw significant advances in military technology, including machine guns, tanks, airplanes, and submarines.
Western Front: The Western Front was the main theatre of World War I in Europe, stretching from the English Channel to the Swiss border and characterized by trench warfare.
Eastern Front: The Eastern Front was a theatre of World War I in eastern Europe, characterized by mobile warfare and significant territorial gains and losses by both sides.
The Battle of the Somme: The Battle of the Somme was a major offensive by British and French forces in 1916, resulting in heavy casualties and little territory gained.
United States Entry Into World War I: The United States entered World War I in 1917, largely due to factors such as unrestricted submarine warfare by Germany and the interception of the Zimmerman Telegram.
Treaty of Versailles: The Treaty of Versailles was the peace treaty signed at the end of World War I, imposing heavy reparations and other penalties on Germany.
Effects of World War I: The effects of World War I were far-reaching, including the collapse of empires, the rise of communism, the Treaty of Versailles, and the destabilization of Europe leading up to World War II.
