In December 1851 and under the pretext of abolishing slavery, the British bombarded Lagos, dislodged Kosoko from the throne, and installed a more amenable Akitoye as Oba of Lagos. Though Akitoye signed a treaty with Britain outlawing the slave trade, Tinubu subverted the 1852 treaty and secretly traded slaves for guns with Brazilians and Portuguese traders.
