INTRODUCTION xi Political office does not carry with it juridical rights over a particular, defined stretch of territory and its inhabitants. Membership of the local community, and the rights and duties that go with it, are acquired as a rule through genealogical ties, real or fictional. The lineage principle takes the place of political allegiance, and th$ interrelations of territorial segments are directly co-ordinated with the interrelations of lineage segments. Political relations are not simply a reflexion of territorial relations. The political system, in its own right, incorporates territorial relations and invests them with the particular kind of political significance they have. X. The Balance of Forces in the Political System A relatively stable political system in Africa presents a balance between conflicting tendencies and between divergent interests. In Group A it is a balance between different parts of the administrative organization. The forces that maintain the supremacy of the paramount ruler are opposed by the forces that act as a check on his powers. Institutions such as the regimental organization of the Zulu, the genealogical restriction of succession to kingship or chiefship, the appointment by the king of his kinsmen to regional chiefships, and the mystical sanctions of his office all reinforce the power of the central authority. But they are counterbalanced by other institutions, like the king's council, sacerdotal officials who have a decisive voice in the king's investiture, queen mothers' courts, and so forth, which work for the protection of law and custom and the control of centralized power. The regional devolution of powers and privileges, necessary on account of difficulties of communication and transport and of other cultural deficiencies, imposes severe restrictions on a king's authority. The balance between central authority and regional autonomy is a very important element in the political structure. If a king abuses his power, subordinate chiefs are liable to secede or to lead a revolt against him. If a subordinate chief seems to be getting too powerful and independent, the central authority will be supported by other subordinate chiefs in suppressing him. A king may try to buttress his authority by playing off rival subordinate chiefs against one another. It would, be a mistake to regard the scheme of constitutional checks and balances and the delegation of power and authority to
