The 1926 Slavery Convention or the Convention to Suppress the Slave Trade and Slavery was an international treaty created under the auspices of the League of Nations and first signed on 25 September 1926. It was registered in League of Nations Treaty Series on 9 March 1927, the same day it went into effect. The objective of the convention was to confirm and advance the suppression of slavery and the slave trade.
In the Brussels Conference Act of 1890, the signatories "declared that they were equally animated by the firm intention of putting an end to the traffic in African slaves". It was supplemented and revised by the Convention of Saint-Germain-en-Laye, signed by the Allied Powers of the First World War on 10 September 1919, in which the signatories undertook to "endeavour to secure the complete suppression of slavery in all its forms and of the slave trade by land and sea" (Article 11).
A Temporary Slavery Commission was appointed by the Council of the League of Nations in June 1924. The commission was mixed in composition including former colonial governors, as well as a Haitian, and a representative from the International Labour Organization, Frederick Lugard, was the British representative on the commission.
The convention established concrete rules and articles to advance the suppression of slavery and the slave trade.
Slavery was defined in Article 1 as
the status or condition of a person over whom any or all of the powers attaching to the right of ownership are exercised
The slave trade was defined as including
all acts involved in the capture, acquisition or disposal of a person with intent to reduce him to slavery; all acts involved in the acquisition of a slave with a view to selling or exchanging him; all acts of disposal by sale or exchange of a slave acquired with a view to being sold or exchanged, and, in general, every act of trade or transport in slaves.
The parties agreed to prevent and suppress the slave trade and to progressively bring about the complete elimination of slavery in all its forms.
The parties undertook to promulgate severe penalties for slave trading, slaveholding, and enslavement.
