Germany, Bulgaria and the Ottoman Empire.
The Austro-Hungarian Empire, which was dissolved following World War I, was led by Emperor Franz Josef I. By the time the war started, Franz Josel was in his eighties, so his military forces were led by General von Hotzendorf until by General von Hötzendorf. When Emperor Franz Josef died in 1916 and Emperor Karl I succeeded to the throne, he took over as leader of the army and navy.
I believe you are asking what started World War I and that would be the assassination of the Austria-Hungary leader
Germany, Bulgaria and Turkey were Austria Hungary's allies during WW1.GermanyGermany was one.
If you're talking about Austria-Hungary and the one whose death started World War I, that would be Archduke Franz Ferdinand. During World War II, considering that it started in 1939, Austria was already a part of Nazi Germany, making Hitler the leader of Austria (and all other German countries excluding Switzerland and Liechtenstein). Not sure who was in charge of Hungary during this time...
There was no Austria-Hungary after WWI it was broken up after the first world war
Joseph Ferdinand
Austria-Hungary
Germany and Italy
Franz Josef
That would be Archduke Franz Ferdinand of Austria.
In world war 1, Serbians shot Austria-Hungary's leader witch started the whole thing, and Britain and the other Allies destroyed Germany's economy. And as for World War 2, Adolf Hitler and Japan started taking over many countries.
