Organized crime in the Balkans has its roots in the traditional clan structures. In these largely rural countries, people organized into clans with large familial ties for protection and mutual assistance. Starting in the 15th century, clan relationships operated under the kanun, or code, which values loyalty and besa, or secrecy. Each clan established itself in specific territories and controlled all activities in that territory. Protection of activities and interests often led to violence between the clans. The elements inherent in the structure of the clans provided the perfect backbone for what is considered modern-day Balkan organized crime.
