Although we have often wondered what people in African during the 19th century knew of Haiti, there is a brief mention of the Haitian Revolution in Kano. Hugh Clapperton, who traveled to Borno and the Sokoto Caliphate in the 1800s, recounted this particular episode in his Journal of a Second Expedition Into the Interior of Africa: From the Bight of Benin to Soccatoo, published in 1829. According to Clapperton, an Arab merchant residing in Kano was killed by his female slaves. According to his informants, the custom was to sell such slaves toward the coast. Clapperton, when asked what should be done, endorsed hanging the slaves once it was clear they had killed their master from Ghadamis. Naturally, this led to Clapperton's curiosity about the slave population in Kano. Surprisingly, it was thirty slaves for every free man. Given these demographics, Clapperton used the example of St. Domingo (Haiti) as a warning to the people of Kano, since slaves may rise up and seize control when they overwhelmingly outnumber their masters. Besides the example of Haiti, which we presume was either unknown or poorly understood in West Africa, Clapperton cited recent history of the Hausa slaves in Oyo who rebelled.
