Whereas the signatories of the General Act of the Brussels Conference of 1889-90 declared that they
were equally animated by the firm intention of putting an end to the traffic in African slaves,
Whereas the signatories of the Convention of Saint-Germain-en-Laye of 1919, to revise the General
Act of Berlin of 1885 and the General Act and Declaration of Brussels of 1890, affirmed their intention
of securing the complete suppression of slavery in all its forrns and of the slave trade by land and sea,
Taking into consideration the report of the Temporary Slavery Commission appointed by the Council of
the League of Nations on June 12th, 1924,
Desiring to complete and extend the work accomplished under the Brussels Act and to find a means of
giving practical effect throughout the world to such intentions as were expressed in regard to slave
trade and slavery by the signatories of the Convention of Saint-Germain-en-Laye, and recognising that
it is necessary to conclude to that end more detailed arrangements than are contained in that
Convention,
Considering , moreover, that it is necessary to prevent forced labour from developing into conditions
analogous to slavery,
Have decided to conclude a Convention and have accordingly appointed as their Plenipotentiaries [
names omitted ]
... have agreed as follows:
Article 1
For the purpose of the present Convention, the following definitions are agreed upon:
(1) Slavery is the status or condition of a person over whom any or all of the powers attaching to the
right of ownership are exercised.
(2) The slave trade includes 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.
Article 2
The High Contracting Parties undertake, each in respect of the territories placed under its sovereignty,
jurisdiction, protection, suzerainty or tutelage, so far as they have not already taken the necessary
steps:
( a ) To prevent and suppress the slave trade;
( b ) To bring about, progressively and as soon as possible, the complete abolition of slavery in all its
forms.
Article 3
2
The High Contracting Parties undertake to adopt all appropriate measures with a view to preventing
and suppressing the embarkation, disembarkation and transport of slaves in their territorial waters and
upon all vessels flying their respective flags.
The High Contracting Parties undertake to negotiate as soon as possible a general Convention with
regard to the slave trade which will give them rights and impose upon them duties of the same nature
as those provided for in the Convention of June 17th, 1925, relative to the International Trade in Arms
(Articles 12, 20, 21, 22, 23, 24 and paragraphs 3, 4 and 5 of Section II of Annex II), with the
necessary adaptations, it being understood that this general Convention will not place the ships (even
of small tonnage) of any High Contracting Parties in a position different from that of the other High
Contracting Parties.
It is also understood that, before or after the coming into force of this general Convention, the High
Contracting Parties are entirely free to conclude between themselves, without, however, derogating
from the principles laid down in the preceding paragraph, such special agreements as, by reason of
their peculiar situation, might appear to be suitable in order to bring about as soon as possible the
complete disappearance of the slave trade.
Article 4
The High Contracting Parties shall give to one another every assistance with the object of securing the
abolition of slavery and the slave trade.
Article 5
The High Contracting Parties recognise that recourse to compulsory or forced labour may have grave
consequences and undertake, each in respect of the territories placed under its sovereignty,
jurisdiction, protection, suzerainty or tutelage, to take all necessary measures to prevent compulsory
or forced labour from developing into conditions analogous to slavery.
It is agreed that:
(1) Subject to the transitional provisions laid down in paragraph (2) below, compulsory or forced
labour may only be exacted for public purposes.
(2) In territories in which compulsory or forced labour for other than public purposes still survives, the
High Contracting Parties shall endeavour progressively and as soon as possible to put an end to the
practice. So long as such forced or compulsory labour exists, this labour shall invariably be of an
exceptional character, shall always receive adequate remuneration, and shall not involve the removal
of the labourers from their usual place of residence.
(3) In all cases, the responsibility for any recourse to compulsory or forced labour shall rest with the
competent central authorities of the territory concerned.
Article 6
Those of the High Contracting Parties whose laws do not at present make adquate provision for the
punishment of infractions of laws and regulations enacted with a view to giving effect to the purposes
of the present Convention undertake to adopt the necessary measures in order that severe penalties
may be imposed in respect of such infractions.
Article 7
The High Contracting Parties undertake to communicate to each other and to the Secretary-General of
the League of Nations any laws and regulations which they may enact with a view to the application of
the provisions of the present Convention.
Article 8
3
The High Contracting Parties agree that disputes arising between them relating to the interpretation or
application of this Convention shall, if they cannot be settled by direct negotiation, be referred for
decision to the Permanent Court of International Justice. In case either or both of the States Parties to
such a dispute should not be Parties to the Protocol of December 16th, 1920, relating to the
Permanent Court of International Justice, the dispute shall be referred, at the choice of the Parties and
in accordance with the constitutional procedure of each State, either to the Permanent Court of
International Justice or to a court of arbitration constituted in accordance with the Convention of
October 18th, 1907, for the Pacific Settlement of International Disputes, or to some other court of
arbitration.
Article 9
At the time of signature or of ratification or of accession, any High Contracting Party may declare that
its acceptance of the present Convention does not bind some or all of the territories placed under its
sovereignty, jurisdiction, protection, suzerainty or tutelage in respect of all or any provisions of the
Convention; it may subsequently accede separately on behalf of any one of them or in respect of any
provision to which any one of them is not a Party.
Article 10
In the event of a High Contracting Party wishing to denounce the present Convention, the denunciation
shall be notified in writing to the Secretary-General of the League of Nations, who will at once
communicate a certified true copy of the notification to all the other High Contracting Parties,
informing them of the date on which it was received.
The denunciation shall only have effect in regard to the notifying State, and one year after the
notification has reached the Secretary-General of the League of Nations.
Denunciation may also be made separately in respect of any territory placed under its sovereignty,
jurisdiction, protection, suzerainty or tutelage.
Article 11
The present Convention, which will bear this day's date and of which the French and English texts are
both authentic, will remain open for signature by the States Members of the League of Nations until
April 1st, 1927.
The Secretary-General of the League of Nations will subsequently bring the present Convention to the
notice of States which have not signed it, including States which are not Members of the League of
Nations, and invite them to accede thereto.
A State desiring to accede to the Convention shall notify its intention in writing to the Secretary-
General of the League of Nations and transmit to him the instrument of accession, which shall be
deposited in the archives of the League.
The Secretary-General shall immediately transmit to all the other High Contracting Parties a certified
true copy of the notification and of the instrument of accession, informing them of the date on which
he received them.
Article 12
The present Convention will be ratified and the instruments of ratification shall be deposited in the
office of the Secretary-General of the League of Nations. The Secretary-General will inform all the High
Contracting Parties of such deposit.
The Convention will come into operation for each State on the date of the deposit of its ratification or
of its accession.
