The Unione Corse is a secret criminal organization organizing primarily out of Corsica and Marseilles in France. Unlike the Mafia it has not tried to gain a foothold in the United States and does not have the organization's notoriety. It was the primary organizer of the French Connection and was active between 1950 and 1970.
The symbol of the Unione Corse is the same as the symbol for Corsica generally: the Maure, or Moor's Head, a depiction of a black human head with a rag tied around the forehead, on a white field. In the case of a member of this society, this symbol is often worn as a pendant or a watch fob.
