In 1882, the British introduced a memorandum of a proposed anti slavery legislation for the Porte, and in 1883, they put forward a second draft law.
In anticipation of the Brussels Anti-Slavery Conference 1889–90, which was due to take place in November 1889, the British diplomatic campaign on the Porte finally had a breakthrough.
[2] The British diplomatic pressure finally gave results when Sultan Abdul Hamid II introduced the Kanunname of 1889 on 30 December 1889.
It also importantly introduced a legal procedure to search and investigate the crime, as well as an actual punishment, with a fine of five Ottoman lira for slave trade.
The Kanunname of 1889 was introduced in order for the Ottoman Empire to be able to attend the Brussels Anti-Slavery Conference without being subjected to criticism for their bad enforcement of the previous Anglo-Ottoman Convention of 1880, and this goal was achieved.
