The Full Story
Lagos in 1851 was one of the last major slave ports in West Africa. King Kosoko had seized power and expanded the slave trade, exporting thousands of people each year to Brazil and Cuba.
Britain decided to remove him.
The first attack failed. The shallow lagoon protected Lagos, and British boats couldn't get close enough. Kosoko's forces drove them back with heavy casualties. It was an embarrassing defeat.
Behind the intervention stood Samuel Ajayi Crowther. Crowther was a Yoruba man who had been captured as a child and freed by the Royal Navy. He had become a Christian missionary, and in London he made the case for action in person, before Queen Victoria and Lord Palmerston. His advocacy helped push Britain to act.
The second attack, in December 1851, succeeded. Kosoko fled. Britain installed Akitoye, a rival who had promised to end the slave trade. Lagos's slave markets closed.
The intervention was controversial even then. But it worked. One of Africa's largest slave ports was shut down, with crucial help from a man who had once been its victim.
Why This Matters
The Lagos intervention shows both the complexity and effectiveness of British abolition. Military action, African allies, and freed slaves all played crucial roles.
