of the crime family who report directly to the boss, the capobastone (head of command). Power structure For many years, the power apparatus of the single families were the sole ruling bodies within the two associations, and they have remained the real centres of power even after superordinate bodies were created in the Cosa Nostra beginning in the 1950s (the Sicilian Mafia Commission) and in the 'Ndrangheta a superordinate body was created only in 1991 as the result of negotiations to end years of inter-family violence. However, the absolute autonomy of Calabrian crime families prior to this is not supported by historical evidence. At least since the end of the 19th century, some stable mechanisms for coordination and dispute settlement have existed. Contacts and meetings among the bosses of the locali were frequent. A new investigation, known as Operation Crimine, which ended in July 2010 with an arrest of 305 'Ndrangheta members revealed that the 'Ndrangheta was extremely "hierarchical, united and pyramidal," and not just clan-based as previously believed, as said by Italy's chief anti-mafia prosecutor Pietro Grasso. At least since the 1950s, the chiefs of the 'Ndrangheta locali have met regularly near the Sanctuary of Our Lady of Polsi in the municipality of San Luca during the September Feast. These annual meetings, known as the crimine, have traditionally served as a forum to discuss future strategies and settle disputes among the locali. The assembly exercises weak supervisory powers over the activities of all 'Ndrangheta groups. Strong emphasis was placed on the temporary character of the position of the crimine boss. A new representative was elected at each meeting. Far from being the "boss of bosses," the capo crimine actually has comparatively little authority to interfere in family feuds or to control the level of interfamily violence. At these meetings, every boss "must give account of all the activities carried out during the year and of all the most important facts taking place in his territory such as kidnappings, homicides, etc." The historical preeminence of the San Luca family is such that every new group or locale must obtain its authorization to operate and every group belonging to the 'Ndrangheta, "still has to deposit a small percentage of illicit proceeds to the principale of San Luca in recognition of the latter's primordial supremacy." Security concerns have led to the creation in the 'Ndrangheta of a secret society within the secret
