Serbia and Montenegro consisted of two republics, Serbia with its capital in Belgrade and Montenegro with its capital in Podgorica.
Serbia had two autonomous provinces (autonomna pokrajina / аутономна покрајина): The part of Serbia that was in neither (often called "Central Serbia") was not a province and had no special status.
Independently of this division, Serbia was further divided into 29 districts (okrug / округ) and the city of Belgrade.
Each of districts (and the city) was further divided into municipalities (општина / opština).
Montenegro was divided into 21 municipalities (opština / општина).
