Social Organization. Tonga society was once strongly egalitarian despite differences in wealth and the existence of slavery. Slaves were incorporated into the descent group of the owner, and they or their descendants might then be chosen as spirit guardians. The colonial administration abolished slavery. Today few know whose ancestors were or were not slaves. Lineages claiming priority of settlement within a neighbor.hood were said to hold katongo in that area, which amounted to a right to provide custodians for local shrines and sometimes a right to receive a portion of game killed. In southern Gwembe, status differences were more apparent. Today status reflects success in exploiting new economic opportunities, including education. Teachers and others with technical training, along with shop owners and wealthier farmers, form an emerging rural elite.
Political Organization. The Republic of Zambia is a single-party state organized into provinces and districts with their own administrations. Districts are divided into wards, and these into branches and sections. Elected councillors provide the effective grassroots political organization and have replaced the chieftaincy/village hierarchy that was the backbone of the colonial administration. Chiefs and village headmen still exist, but headmen have few functions, and chiefs act primarily as land allocators and ceremonial heads. Political initiative flows from the central government. As much as possible, the Tonga maintain their independence by avoiding contact with authority except when it might work to their advantage-Prior to the colonial era, and even much later, political leadership was usually provided by "big-men," whose exercise of power did not create a permanent office. Hereditary political office was the exception. Usually the political community was the neighborhood, of perhaps a thousand people, whose name derived from a geographical feature. Political authority was shared by senior men and women who assembled to settle disputes and organize communal rituals. Neighborhood residents were expected to attend each other's funerals. They had to observe ritual restrictions associated with "the work of the neighborhood," which centered on the agricultural cycle. They came together at local shrines to appeal for rain. Neighborhoods are still important under the party organization. Branch and section councillors summon people for communal labor: repairing roads, building additions to the local school, and other community work. Gwembe neighborhoods also have drum teams that perform at local funerals and represent the neighborhood on ceremonial occasions.
Social Control. Homestead members were expected to settle their own differences. Neighborhood moots dealt with quarrels between descent groups or general issues. Direct action to enforce rights or redress injury was common, but crosscutting ties of kinship damped down the possibility for prolonged feuding. Gossip and the fear of sorcery were important mechanisms of social control. The colonial administration instituted chief's courts and delegated to headmen the right to settle village disputes. Messengers attached to the chief's court provided an embryonic police force, reinforced by district messengers under the authority of the district commissioner. In 1964 elected party officers took over adjudication at the neighborhood level, and local courts are no longer under the jurisdiction of chiefs. Courts are responsible to the Ministry of Justice, which appoints their members and regulates procedures. Courts are still expected to operate within customary law unless it clashes with national legislation. Police units, party vigilantes, and other representatives of the central government are constant reminders of the centralization of authority.
Conflict. In years of hunger, neighborhood once raided neighborhood to obtain food, and neighbor stole from neighbor. In the Zambezi plain, lineage members quarreled over the allocation of alluvial fields, and adjacent cultivators accused each other of moving boundary marks. When cattle or other stock invaded fields, damages were demanded. There were quarrels over adultery, the flight of wives, and failure to meet marriage payments. Deaths, illnesses, and other misfortune led to accusations of sorcery. Many of these grounds for conflict still exist, and theft of livestock has increased vastly, as has armed banditry along the roads. The availability of alcohol, since beer has become commercialized, has increased the amount of physical violence.
