World War One, also known as the Great War, began in July 1914. The immediate cause of the war was the assassination of Archduke Franz Ferdinand of Austria-Hungary on June 28, 1914. This event sparked a chain reaction of political and military alliances that ultimately led to the outbreak of war in Europe.

July 28, 1914, is considered the official start date of World War One, as Austria-Hungary declared war on Serbia, setting off a series of declarations of war among the major European powers. The conflict would eventually involve countries from around the world and result in millions of deaths.

The war lasted for over four years, with fighting taking place on multiple fronts and involving new technologies such as tanks, airplanes, and chemical weapons. The toll of the war was immense, with an estimated 16 million people killed and millions more wounded or missing.
