Ukrainian mafia

Ukrainian mafia is a type of criminal organization with origins in Ukraine. Such organizations are regarded as one of the most influential types of organized crime coming out of the former USSR, including also the Russian mafia, the Georgian mafia, the Chechen mafia, the Armenian mafia and the Azerbaijani mafia. Ukrainian criminal organizations are involved in a significant number of illegal activities. Although Ukrainian criminal organizations are for the most part independently operating enterprises, they are sometimes connected with Russian mafia organizations, such as the case with Semyon Mogilevich.[1]
