How about population? How would somalis go about industrialising in that period when our total population didnt even break the threshold of 1 Million if we compare it to the japanese pre industrialisation their population was at 30 Million, A Healthy number to implement industrialisation and growth.I looked at the ref to it and it says Sokoto was a slave society.

Somali societies had more diversified trade developments and networks.
For example our textile industry was larger it was the one of the most dominant in Africa, especially in East Africa and they got incredibly wealthy from it continued throughout the 1800s until the early 1900s, exporting finished garments, shawls and artisanal caps.
It managed to even stay competitive against American textile exports:
And this is just southern Somalia alone, Harar textiles and tailored garments probably compounded that several folds i am looking more into.
