Apis, Black Hand leader executed by own government.
Dimitrijevic, as a junior officer, participated in the conspiracy that assassinated King Aleksandar Obrenovic and Queen Draga. The coup brought the Karadjordjevic dynasty to power and ended the Obrenovic rule in Serbia.
Dimitrijevic co-founded the secret military society 'Unification or Death' (Black Hand). The organization aimed to unite all Serbs through revolutionary action, using terrorist methods to achieve its goals.
Dimitrijevic, as head of Serbian military intelligence, allegedly provided weapons and training to the assassins who killed Archduke Franz Ferdinand in Sarajevo. This event triggered the July Crisis and the outbreak of World War I.
Dimitrijevic was arrested, tried by a Serbian military court in Thessaloniki, and executed by firing squad. The trial was politically motivated, aimed at removing the Black Hand's influence from the Serbian army and government.
