Unification or Death, popularly known as the Black Hand, was a secret military society formed in 1901 by officers in the Army of the Kingdom of Serbia. It gained a reputation for its alleged involvement in the assassination of Archduke Franz Ferdinand in Sarajevo in 1914 and for the earlier assassination of the Serbian royal couple in 1903, under the aegis of Captain Dragutin Dimitrijević.
