1892–1950 The
British Empire, having signed the
1926 Slavery Convention as a member of the
League of Nations, was obliged to fight slavery and the slave trade in all land under the direct or indirect control of the British Empire. Since the Trucial States were informally a
British protectorate, the British were expected by the
League of Nations to enforce this policy in the region. Officially, the British declared that they did just that, but in reality, the slavery and slave trade in the Trucial States were tolerated by the British. As was the case with the rest of the Gulf states, the British considered their control over the region insufficient to do much about slavery and the slave trade. The British
India Office advised the British authorities that any attempts to enforce an anti-slavery treaty in the region could cause economic and political unrest, since slavery was "deeply rooted in religious and political history".
1950–1970 After
World War II, there was a growing international pressure from the United Nations to end the slave trade. After the Independence of India in 1947, the
British Foreign Office secured direct control over the Trucial States and for the first time considered itself to have sufficient control to enforce the laws against slavery and slave trade, particularly since a bigger international presence in the Gulf States attracted more attention to the slavery, and a stronger international condemnation against it. In 1948, the United Nations declared slavery to be a crime against humanity in the
Universal Declaration of Human Rights, after which the
Anti-Slavery Society pointed out that there were about one million slaves in the Arabian Peninsula, which was a crime against the
1926 Slavery Convention, and demanded that the UN form a committee to handle the issue. The UN formed the
Ad Hoc Committee on Slavery in 1950, which resulted in the introduction of the
Supplementary Convention on the Abolition of Slavery. The Ad Hoc Committee on Slavery filed a report on the chattel slavery in the Trucial States during the 1950-1951 investigation. In 1951 the British founded the Trucial Oman Levies or Trucial Oman Scouts in Sharjah to fight the slave trade. When
slavery in Qatar was abolished in 1952 the British asked the Trucial Council assembly of Trucial rulers to follow their example and abolish slavery, but they refused, stating that slavery was legal in Islam, and that they lacked the funds to pay compensation to slave owners. The
1956 Supplementary Slavery Convention differed between "non-self-governing territories" and "other non-metropolitan territories" such as the Persian Gulf states, and the British stated that the Convention did not apply to the Trucial states, but encouraged the Trucial rulers to abolish slavery and apply the Convention voluntarily. In 1957 the British pressured the Gulf rulers to accept the
1956 Supplementary Slavery Convention in accordance with the Colonial Application; this was accepted by Kuwait, Qatar and Bahrain, but the rulers of the Trucial States stated that such a law could not be enforced. When the Trucial rulers did accept the
1956 Supplementary Slavery Convention, they did not follow it up with issuing the necessary edicts, and the British regarded the issue as too sensitive to pressure them to do so. In 1958 the British Political Agent in Dubai
Peter Tripp urged the Trucial rulers to issue a decree, ''a'lan'', to prohibit slavery and fulfil the obligations of the
1956 Supplementary Slavery Convention. The Trucial rulers claimed that slavery was already defunct but that they would issue such a decree if the British government wished them to. In 1963, the British Political Resident Sir
William Luce reported that the Trucial rulers had finally signed an agreement to issue a decree to follow the
1956 Supplementary Slavery Convention; they claimed that they had indeed issued such a decree, but the British could find no evidence to confirm that such a decree had ever been issued. ==After independence: the United Arab Emirates==
