land is passed down through the male lineage; fore culture is heavily patrilineal. boys marry and remain on the land on which their fathers lived. daughters of one clan typically marry into many different clans, but these marriage alliances often do not last long. conflict often arises over unused land for expansion of farming and grazing, and villages or kinship groups will often band together to defend territory. generally, these battles are fought with bows and arrows as the primary weapon. settlements are temporary; a group will flee when they lose a battle over their land and will take refuge with other groups of friends or relatives.
