The Black Hand
The Black Hand was formed when ten men met on 9 May 1911 to form Ujedinjenje ili Smrt (Unification or Death), better known as the Black Hand.
By 1914, there were many hundred members, perhaps as many as 3500. Many members were Serbian army officers. The professed goal of the group was the creation of a Greater Serbia, by use of violence, if necessary. The Black Hand trained guerillas and saboteurs and planned political murders. The Black Hand was organized at the grassroots level in 3- to 5-member cells, supervised by district committees and by a Central committee in Belgrade whose ten-member Executive Committee was led, more or less, by Colonel Dragutin Dimitrijević (also known as Apis). To ensure secrecy, members rarely knew much more than the members of their own cell and one superior above them. New members swore "I (...), by entering into the society, do hereby swear by the Sun which shineth upon me, by the Earth which feedeth me, by God, by the blood of my forefathers, by my honour and by my life, that from this moment onward and until my death, I shall faithfully serve the task of this organisation and that I shall at all times be prepared to bear for it any sacrifice. I further swear by God, by my honour and by my life, that I shall unconditionally carry into effect all its orders and commands. I further swear by my God, by my honour and by my life, that I shall keep within myself all the secrets of this organisation and carry them with me into my grave. May God and my brothers in this organisation be my judges if at any time I should wittingly fail or break this oath."[9]

Just prior to World War I, under the orders of the Chief of Serbian Military Intelligence, Serbian Military Officers and remnants of the by then moribund Black Hand organized and facilitated the assassination of Franz Ferdinand, Archduke of Austria on occasion of his visit to Sarajevo, Bosnia. The Austro-Hungarian investigation of the assassination rounded up all but one of the assassins and also much of the underground railroad that had been used to transport the assassins and their weapons from Serbia to Sarajevo. Within two days following the assassination, Austria-Hungary and Germany advised Serbia that they should open an investigation, but Serbian Foreign Minister Gruic, speaking for Serbia replied, "Nothing had been done so far, and the matter did not concern the Serbian Government," after which "high words" were spoken on both sides. Entreaties by Germany asking Russia to intercede with Serbia were ignored. On 23 July Austria-Hungary delivered a toughly worded letter to Serbia with ten enumerated demands and additional demands in the preamble aimed at the destruction of the anti-Austrian terrorist and propaganda network in Serbia. Austria called attention to Serbia's March 1909 declaration committing to the Great Powers to respect Austria-Hungary's sovereignty over Bosnia-Herzegovina and committing Serbia to maintain good neighborly relations with Austria-Hungary. If the ten enumerated demands and demands in the preamble were not agreed to within 48 hours, Austria-Hungary would recall its ambassador from Serbia. The letter became known as the July Ultimatum. Serbia accepted all but one of the demands, to let the Austrian officers conduct an investigation on Serbian soil, which would have compromised its sovereignty. In response, Austria-Hungary recalled its ambassador.
