Answer 1

im doing a report at the moment on this :

The first world wars beginning

What sparked it was the assassination of Archduke Franz Ferdinand, heir to the Austro-Hungarian throne in Sarajevo on 28 June 1914. Ferdinand's death was by the hand of the Black Hand, a Serbian pro-self-government secret society.

This set in motion an automated series of events that culminated in the world's first global war.

Austria-Hungary's reaction to the death of their heir came in three weeks. Arguing that the Serbian government was implicated in the plotting of the Black Hand, the Austro-Hungarians opted to take the opportunity to stamp its authority upon the Serbians. Crushing the movement for self-government there and cementing Austria-Hungary's influence in the Balkans (a region of southeastern Europe)

It did so by issuing an ultimatum to Serbia which, in the extent of its demand that the assassins be brought to justice effectively nullified Serbia's authority.

Austria-Hungary's expectation was that Serbia would reject the remarkably severe terms of the ultimatum, thereby giving her a pretext for launching a limited war against Serbia.

Serbia had long had Slavic ties with Russia, while Austria-Hungary didn't have such a strong relationship. Austria-Hungary was not expecting that Russia would be drawn into the dispute to any great extent. A

Austro-Hungarian government sought assurances from her ally, Germany, that she would come to her aid should the unthinkable happen and Russia declared war on Austria-Hungary.

Germany readily agreed, even encouraged Austria-Hungary's warlike stance.

So then, we have the following remarkable sequence of events that led inexorably to the 'Great War'

Austria-Hungary, unsatisfied with Serbia's response to her declared war on Serbia on 28 July 1914.

Russia, bound by treaty to Serbia, announced mobilization of its vast army in her defense, a slow process that would take around six weeks to complete.

Germany, allied to Austria-Hungary by treaty, viewed the Russian mobilization as an act of war against Austria-Hungary, and after scant warning declared war on Russia on 1 August.

France, bound by treaty to Russia, found itself at war against Germany and, by extension, on Austria-Hungary following a German declaration on 3 August. Germany was swift in invading neutral Belgium so as to reach Paris by the shortest possible route.

Britain, allied to France by a more loosely worded treaty which placed a "moral obligation" upon her to defend France, declared war against Germany on 4 August. Her reason for entering the conflict lay in another direction: she was obligated to defend neutral Belgium by the terms of a 75-year old treaty.

With Britain's entry into the war, her colonies and dominions abroad variously offered military and financial assistance, and included Australia, Canada, India, New Zealandand the Union of South Africa.
