The Geg clans put great importance on marriage traditions. Marriage customs and prohibitions designed to perpetuate these traditions were still practiced at the end of World War II. According to the custom a young man from a given clan always married a young woman from outside the clan but from within the same tribe. In some tribes marriages between Christians and Muslims were tolerated even before the advent of the Communist regime, but as a rule such marriages were frowned upon. A variety of offenses against women served as an igniting spark for blood feuds. Many girls were engaged to marry in their infancy by their parents. If later the girl did not wish to marry the man whom the parents had chosen for her and married another, in all likelihood a blood feud would ensue. Among the Tosks, religious beliefs and customs, rather than clan and tribal traditions, were more important in regulating marriages. The family had for centuries presented the basic, most important unit in the social structure of the country. One aspect of this was the deep devotion of a person to his parents and family. This feeling took a striking form because the family was a social unit occupying to a great extent the place of the state. Children were brought up to respect their elders and, above all, their father, whose word was law in the confines of his family. Upon the death of the father the authority of the family devolved upon the oldest male of the family. The females of the household, with the exception of the mother, occupied an inferior position. The unwritten law of family life was based on the assumption that a daughter was part of the family until she married. When the time came for sons to set up their own households, all parental property was equally divided among them; the females did not share in this division. Geographical conditions affected Tosk social organization. The region's accessibility led to its coming much more firmly under Turkish rule. This rule in turn resulted in the breakup of the large, independent family-type units and their replacement by large estates owned by powerful Muslim landowners, each with his own retinues, fortresses, and large numbers of tenant peasants to work the lands. Their allegiance to the sultans in the period before 1912 was secured by the granting of administrative positions either at home or elsewhere in the Ottoman Empire.
