Vendettas could go on for months, sometimes years, and usually ended when one family was exterminated or left the town. In some cases (like the tit for tat killing of a murderer) vendettas would be concluded after the 'guilty' individual(s) were killed. In other cases vendettas, particularly long-running ones, were ended in a peaceful to terms or exchange of property. In the case of long vendettas, families often agreed upon a temporary (, 'truce') in order to allow for crop harvests or the attendance of religious ceremonies; when the ended, the killing could resume. A cornerstone of the Maniot's vendetta culture was the agreement that all vendettas immediately stop in a universal whenever the community faced a Turkish threat. The longest of all was announced by the Mavromichalis clan when war was declared on the Ottoman Empire in March 1821, beginning the Greek War for Independence. Vendettas continued after the liberation of Greece even though the Regency tried to demolish the towers. The Maniot vendetta culture is considered one of the most vicious and ruthless of all the Mediterranean vendetta cultures. One of the last large scale vendettas on record required the Greek Police, 1,000 Greek Army soldiers, and 200 Greek Navy sailors to stop.
