Golden age

The Scramble

Sign or stand
November 1895. Oyo signed treaties with Britain in 1888 and 1893. Now Captain R. L. Bower arrives from the Lagos Protectorate with soldiers, a field gun and a Maxim gun, and demands that the Alaafin submit to British authority.
| Sign | Submit, as the treaties require. Alaafin Adeyemi I keeps his throne under British rule, but Unity falls hard for a month. |
| Stand | Refuse the demands and face Bower’s column. Hold the palace and history changes. |
What really happened (the game tells you at the end)
On 12 November 1895 Bower’s force bombarded Oyo, and by 1896 the kingdom’s independence was over. Adeyemi I stayed Alaafin under British rule until 1905, and in 1906 Yorubaland was merged into Southern Nigeria. Your city rebuilds: the column will come again while you stay in the Scramble.
