Dragutin Dimitrijevic is a founding member and inspirational leader of the nationalistic Serbian secret society Ujedinjenje ili Smrt (“Union or Death”), better known as the Black Hand, which from its inception in 1911 seeks to create a Greater Serbia through the use of violence.

A professor of tactics at the military academy in Belgrade, he exerts considerable influence over his students, and he fosters Serbian nationalistic activity abroad.

The society's members are primarily army officers with some government officials.

Operating from Belgrade, it conducts propaganda campaigns, organizes armed bands in Macedonia, and establishes a network of revolutionary cells throughout Bosnia.

Within Serbia, it dominates the army and wields tremendous influence over the government by terrorizing officials.
