Introduction
The First World War, lasting from 1914 to 1918, marked a fundamental turning point in 20th-century history. It involved many of the world’s great powers, divided into two main alliances: the Allies (primarily France, Russia, and Great Britain) and the Central Powers (mainly Germany, Austria-Hungary, and the Ottoman Empire). Although the war erupted suddenly in July 1914, its roots extended far back into the 19th century and early 20th century.
To fully understand why the war began, one must examine the political tensions, military alliances, imperial rivalries, nationalist movements, and immediate events that created a volatile environment in Europe. shutdown123
