At least since the 1950s, 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.
From the beginning of the 1960s until the outbreak of the first 'Ndrangheta war in 1975 the position of capo crimine was held by Antonio Macrì from Siderno. Since the mid-1970s, according to several pentiti, members of the Nirta family from San Luca and the Piromalli family from Gioia Tauro rotated among themselves the position of capo crimine.
