World War I, better known as The 'Great War', began on 28th of July, 1914 with the assassination of Austrian Archduke Franz Ferdinand and his wife by a Serbian nationalist in Sarajevo. Austria-Hungary answered with the declaration of war from Austria-Hungary to Serbia. It was the first truly global war.
The “Great War” was a confrontation between the Triple Entente (Britain, France, and Russia) and the Triple Alliance (Austria-Hungary, Germany, and Italy).
|On July 28, Austria-Hungary declared war on Serbia, and the tenuous peace between Europe's great powers collapsed.|
However, Italy did not honor the commitment made with the Triple Alliance because Britain and France offered Italy all those territories that Italy wanted to annex in order to complete the Italian Unification. Britain and France told Italians that they will provide those territories after the victory.
The Great War ended with the Treaty of Versailles, June 28, 1919.
Twenty years later, on August 3, 1934, Adolf Hitler became the supreme leader of Germany to merge the offices of the presidency and the foreign ministry in one: Der Führer or "The German People's Guide spiritually, politically and militarily ".
