Technology is intrinsically rooted within social contexts. Archaeologi
cal approaches which do not take this into account fail to fully under
stand technology. The social contexts of iron production are examined
at Igurwa, an iron-smelting centre within Karagwe, a nineteenth-centur
y African kingdom. At different levels within the society, power was d
erived from the control and manipulation of technical and ritual knowl
edge of iron production. Men excluded women, iron-working clans exclud
ed other clans and the king attempted to maintain control over iron wo
rkers by the use of ritual religion and symbolism. Control of iron pro
duction was essential because of its economic importance but more impo
rtantly because of the symbolic dangers associated with smelting which
threatened the fertility of the state.
