who did austria declare war on in ww1?
serbia
when the war broke out, much of the fighting was between western powers, and the immediate "casus belli" was an assassination. the victim was the heir to the austro-hungarian throne, franz ferdinand, and he was assassinated on 28 june 1914 by a yugoslav nationalist named gavrilo princip in the city of sarajevo, at the time part of the austro-hungarian empire. although serbia agreed to all but one point of the austrian ultimatum (it did not take responsibility in planning the assassination but was ready to hand over any subject involved on its territory), austria-hungary was more than eager to declare war, attacked serbia and effectively began world war i. fearing the conquest of a fellow slavic orthodox nation, russia declared war on austria-hungary. germany responded by declaring war on russia as well as france, which it feared would ally with russia. to reach france, germany invaded neutral belgium in august, leading britain to declare war on germany. the war quickly stalemated, with trenches being dug from the north sea to switzerland. the war also made use of new and relatively new technology and weapons, including machine guns, airplanes, tanks, battleships, and submarines. even chemical weapons were used at one point. the war also involved other nations, with romania and greece joining the british empire and france and bulgaria and the ottoman empire joining germany. the war spread throughout the globe with colonial armies clashing in africa and pacific nations such as japan and australia, allied with britain, attacking german colonies in the pacific. in the middle east, the australian and new zealand army corps landed at gallipoli in 1915 in a failed bid to support an anglo-french capture of the ottoman capital of istanbul. unable to secure an early victory in 1915, british empire forces later attacked from further south after the beginning of arab revolt and conquered mesopotamia and palestine from the ottomans with the support of local arab rebels and supported an arab revolt against the ottomans centered in the arabian peninsula.

bullet::::- "categorical theory", under which the power to declare war includes "the power to control all decisions to enter war". this means that the power to 'declare war' in effect rests with the ability to engage in combat.





















































bullet::::- "pragmatic theory", which states that the power to declare war can be made unnecessary by an act of war in itself.





















































bullet::::- "formalist theory", under which the power to declare war constitutes only a formal documentation of executive war-making decisions. this sits closest to traditional legal conceptions of what it is to declare a war.
