What it is

Excavated, lined pits where indigo is fermented with ash to dye cotton in deep tones. They made Kano one of the great textile centres of the trans-Saharan route.

The date of 1498 is traditional; indigo was used in the region earlier (it already appears in Tellem textiles).

What it led to

  • dyed textiles exported across the Sahara
  • Hausa dyers' guilds
  • the indigo turbans and robes of the Tuareg
