Overview

Anti-Slavery International is a United Kingdom-based nongovernmental organization and registered charity focused exclusively on slavery and related abuses. Founded in London on 17 April 1839 as the British and Foreign Anti-Slavery Society, it emerged from the abolitionist movement that had secured the end of the British transatlantic slave trade and the substantial abolition of slavery across the British Empire. Its original purpose was international: to campaign against slavery in countries where British emancipation had not resolved the wider global system of enslavement. The organization became a significant participant in nineteenth-century abolitionist networks. It helped convene the first World Anti-Slavery Convention in London in 1840, a major international meeting that brought together campaigners from Europe, the United States, and elsewhere. The convention also exposed conflicts within reform movements, particularly over the exclusion of women delegates from formal participation. During the nineteenth century, the society continued to document slavery and support abolitionist activity beyond the British Empire, including work connected with the United States, Africa, the Middle East, and the Ottoman sphere. Its remit broadened during the twentieth century as legal chattel slavery declined but coercive labour systems, colonial exploitation, trafficking, and discrimination persisted. In 1909 it merged with the Aborigines' Protection Society, becoming the Anti-Slavery and Aborigines' Protection Society. The organization campaigned against abuses in the Congo Free State, including the forced labour system associated with King Leopold II, and used photographic evidence in a pioneering public campaign. It also opposed indentured labour in British colonies, supported action concerning indigenous forced labour in the Peruvian Amazon, and contributed evidence and advocacy to the League of Nations' investigation that led to the 1926 Slavery Convention. After the Second World War, Anti-Slavery worked through international institutions, first the League of Nations and later the United Nations. It campaigned against the Red Sea slave trade and slavery in the Arabian Peninsula, contributing to international pressure that accompanied the abolition of slavery in Saudi Arabia in 1962 and subsequent legal abolition in other Gulf and Arabian states. The organization also supported the development of international standards addressing slavery-like practices. The organization changed names several times as its work evolved. It was known as the Anti-Slavery Society from 1947 to 1956, the Anti-Slavery Society for the Protection of Human Rights from 1956 to 1990, and Anti-Slavery International for the Protection of Human Rights from 1990. In 1995 it adopted the shorter name Anti-Slavery International. Its modern work addresses forced labour, debt bondage, child labour, trafficking, domestic servitude, descent-based slavery, exploitative supply chains, and state failures to protect survivors. It combines research, survivor-informed advocacy, litigation and policy lobbying, public campaigning, and collaboration with local civil-society organizations. The organization has worked on bonded labour in Nepal, slavery in Niger, child camel jockeying in the Gulf, forced labour in Indian garment production, trafficking law in the United Kingdom and European Union, domestic workers' rights, and abuses connected with cotton production in Xinjiang. It remains an advocacy organization rather than a commercial product brand.

History

Anti-Slavery International traces its institutional history to the British and Foreign Anti-Slavery Society, established in London on 17 April 1839. The new body was formed after abolitionists concluded that ending slavery in the British Empire did not end slavery globally. Joseph Sturge was central to its creation, while John Harfield Tredgold served as its first secretary and George William Alexander as its first treasurer. The society's first major international initiative was the World Anti-Slavery Convention, held in London in June 1840. It connected abolitionists across national boundaries and made the society an important node in international human-rights advocacy, although the convention's treatment of women delegates revealed divisions within the movement. During the nineteenth century, the society publicized slavery outside the British Empire and supported abolitionist causes in the United States, Africa, and the Middle East. In the 1850s, it assisted John Brown with the preparation and publication of his autobiography. After the abolition of slavery in the United States in 1865, its attention increasingly turned toward remaining systems of enslavement and coercive labour elsewhere. In the early twentieth century, the organization campaigned against forced labour and abuses in the Congo Free State under King Leopold II. The campaign used photographs taken by missionary Alice Seeley Harris, making it an early example of visual documentation being used to mobilize international public opinion. In 1909, the society merged with the Aborigines' Protection Society and became the Anti-Slavery and Aborigines' Protection Society. It later opposed indentured labour in British colonies and supported efforts concerning indigenous labour exploitation in the Peruvian Amazon, including action against the Peruvian Amazon Company in 1921. The society contributed information and advocacy to the League of Nations' study of slavery in the 1920s. That process led to the creation of expert bodies and ultimately to the 1926 Slavery Convention. Although the organization and some international officials believed that legal slavery was nearing its end, later events demonstrated that slavery-like practices and coercive labour remained widespread. Following the Second World War, Anti-Slavery transferred much of its international institutional work to the United Nations system. From 1945 onward it campaigned against the Red Sea slave trade and slavery in the Arabian Peninsula. Its advocacy helped keep the issue on the international agenda during a period when geopolitical relationships limited government action. Saudi Arabia prohibited slave ownership in 1962; abolition followed in other Arabian and Gulf states over subsequent years. The organization was called the Anti-Slavery Society from 1947 to 1956 and the Anti-Slavery Society for the Protection of Human Rights from 1956 to 1990. It became Anti-Slavery International for the Protection of Human Rights in 1990 and adopted the shorter name Anti-Slavery International in 1995. From the late twentieth century onward, its definition of slavery expanded in practical terms to include trafficking, forced labour, debt bondage, domestic servitude, child exploitation, and other situations in which people cannot freely leave exploitative conditions. In the 1990s it supported the ECPAT movement against the sexual exploitation and trafficking of children and helped establish the United Kingdom branch. In the twenty-first century it partnered with organizations in Nepal and Niger on bonded labour and slavery, campaigned against child camel jockeying in the Gulf, supported the former slave Hadijatou Mani in proceedings before the ECOWAS Court, and advocated legislation on trafficking and forced labour in the United Kingdom. It also contributed to campaigns for international standards on domestic workers and exposed forced labour in garment supply chains in India. More recently, its work has included pressure on governments and companies over alleged forced-labour risks in Xinjiang cotton production. The organization continues to combine historical abolitionist campaigning with research, legal advocacy, policy engagement, and partnerships with affected communities.
