Mandamento
Historically a mandamento was the part of Italian territory under the jurisdiction of a "pretore" which is a kind of magistrate. These divisions were abolished in 1923.
Within Cosa Nostra a mandamento is traditionally a district of three geographically contiguous Mafia cosche (families controlling a single land feud, or a city ward) in Sicily. A capo mandamento representing the mandamento is usually entitled to be part of the provincial Mafia Commission.
