WORLD HISTORY

Detailed explanation-1: -The spark that ignited World War I was struck in Sarajevo, Bosnia, where Archduke Franz Ferdinand-heir to the Austro-Hungarian Empire-was shot to death along with his wife, Sophie, by the Serbian nationalist Gavrilo Princip on June 28, 1914.

Detailed explanation-2: -A month after the assassination of Archduke Franz Ferdinand and his wife Sophie on July 28, 1914, the Austro-Hungarian government declares war on Serbia. Immediately, and within a period of six days, European countries declare war upon one another.

Detailed explanation-3: -Until the year 1939, the 1914-18 war was referred to as the “Great War". When war was declared in September and the realisation came that most countries of the world were involved in some way, “Great” became regarded as a misnomer so First was substituted. Logically the 39-45 war became the Second world war.
