The Kanunname of 1889 was a kanunname (Code of law) issued by Sultan Abdul Hamid II on 30 December 1889. It prohibited the importation and sale of African slaves from foreign lands to the Empire. It was introduced due to British diplomatic pressure in anticipation of the Brussels Anti-Slavery Conference 1889–90. The law included the previous anti-slavery decrees in to one code of law. It was the first anti-slavery law that was actually enforced in the Ottoman Empire, and resulted in a reduction of the slave trade.
