JAMB - History (2012 - No. 35)
Sayyid Said increased the volume of trade with the Europeans by
allowing them to take control of the trade with the hinterland
replacing Indian middlemen with Europeans
allowing European consuls to reside in Zanzibar
making English the lingua franca of Zanzibar.
Explication
The European consuls were to ensure compliance with commercial treaties signed between their countries and the Omani rulers and to protect citizens of their countries from molestations.
