What it is

A system of ditches and ramparts several kilometres long, the largest in the Great Lakes, centred on Bigo, beside Ntusi, a herders' settlement with pottery and cattle. They point to hierarchical societies before Bunyoro and Buganda.

Ntusi was occupied c. 1000-1400 and Bigo c. 1300-1500 according to pottery and radiocarbon. The link with the semi-legendary Bachwezi and a Kitara state is an uncorroborated oral tradition. Approximate coordinates.

What it led to

  • archaeology of political complexity in the Great Lakes
  • study of the antecedents of the interlacustrine kingdoms
  • debate on the Bachwezi state
