2021, Forced labour picking cotton in Uzbekistan had almost been eradicated. Before 2017 adults and children were compelled by State law to labour for free picking cotton; child labour was eliminated from 2017 on. In 2015 some 14% of the cotton-picking labour force in Uzbekistan hwas forced labour, falling to 4% in 2020 and reducing further by 2921. The industry has been modernised, with machinery now doing much of the work. Large Western brands such as Nike and Walmart had exterted pressure for Uzbek cotton to be boycotted unless responsibly sourced.

Ca. 10,000, from Angola
13 May 1888. Slavery was abolished in Brazil despite heavy opposition from the landowners. Brazil had agreed to abolish the slave trade, under pressure from Britain, in 1831, but this trade did not cease completely in Brazil until 1853. In the 1860s there was pressure to abolish all slavery in Brazil, and in 1871 the Brazilian parliament passed a law that all children of slave mothers were free. In 1884 Cearas and Amazonas freed their slaves, and in 1885 all Brazilian slaves aged over 65 were freed. Complete emancipation without compensation to landowners was decreed on 13 May 1888 and about 700,000 slaves valued at �40 million (i.e ca.�57 each, or� about �3,800 in 2000 prices) were freed.

The 1494 Treaty moved this line a further 270 leagues to the west. This resulted in Portugal having possession of both Brazil and Africa; in turn this greatly facilitated the expansion of the slave trade, providing cheap labour for the sugar plantations.
9 April 1839, The liberation of slaves in Jamaica was posing severe problems for the landowners, many of whom had treated their slaves brutally.
1838, In Jamaica, Jamaican Governor Sir Lionel Smith read out the proclamation ending slavery on the island.

1 August 1834, Slavery was abolished in all British colonies. �20 million was paid as compensation to former slave owners.� This was a victory for the Anti-Slavery League, formed in 1823, and their Parliamentary leader, Thomas Fowell Buxton. It also completed the work of William Wilberforce; his anti-slavery Bill, to abolish the slave trade, incepted in 1789, was passed in 1807. This move gave impetus to the anti-slavery campaign in the USA.
In South Africa, 35,000 slaves were freed as slavery ended throughout the British Empire. In Barbados the slaves continued to work for their former masters but now as hired servants.
In Jamaica, slave owners were compensated at �19 per slave. However the market rate for a slave then was �35 (�2,000 at 2000 prices). Most of this money in fact went to the plantation creditors, as the plantations were in debt, heavily mortgaged, and in places declining in fertility through overwork. Additionally the UK Government now moved from a Protectionist to a Free Trade stance, eliminiating heavy duties against non-UK-colonial sugar,and sugar prices fell by half.
23 August 1833. London abolished slavery throughout the British Empire. The trade in slaves in Britain had been illegal since 1807. Other European countries slowly followed suit; France continued with the trade till 1819. Spain abolished it in 1820, getting �400,000 compensation from Britain. Portugal abolished the slave trade in 1830, and was paid �300,000 by Britain. Boer farmers in South Africa, facing a loss of this free labour, moved northwards to land outside British control. The Boers were aggrieved that whilst British slave owners in the West Indies received full compensation for the loss of their slaves, Dutch Boer farmers received only one fifth compensation.� Every slave in the British Empire was now nominally free, although to offset the sudden shortage of labour, field slaves were �apprenticed� to their masters till 1840, and domestic slaves till 1838.

29 November 1781, The slave ship Zong sighted land in the West Indies (see 6 September 1781). Collingwood, the ship�s Master, told his officers there was insufficient water for them and all the slaves on board. Dysentery had also plagued the ship on its voyage from Liverpool, killing 60 slaves and 7 crew. Collingwood said if the slaves died of thirst the ship�s owners would bear the loss but if they were thrown overboard the loss would be covered� under insurance as a legal jettison. The weakest 132 slaves were picked out; 54 were thrown overboard that day, 42 the next day, and a further 26 were handcuffed and thrown overboard a few days later. A further ten jumped overboard before they were thrown. On 22 December 1781 the Zong docked at Kingston, Jamaica; the remaining slaves were sold and Collingwood returned to England, and claimed �30 each (�2,200 in 2000 prices) for the 132 �jettisoned� slaves. The insurers refused to pay, and the first trial ruled in favour of Collingwood, saying �it was the same as if horses had been thrown overboard�. The insurers appealed to the Court of Exchequer and Lord Mansfield, judge, ruled otherwise. He said that although the law supported Collingwood, a higher principle applied; distinguishing between �law� and justice� he ruled in this �shocking case� against Collingwood. Mansfield�s ruling was the first in an English Court that a slave was not simply merchandise.
6 September 1781, The slave ship Zong left Liverpool, with Luke Collingwood as its Master, with 400 slaves and 17 crew, see 29 November 1781.

27 September 1672, In Britain, The Royal African Company was granted a monopoly of the African slave trade. A healthy slave could be bought in America for under �20 (approximately �2,000 in 2000 prices), but the trade was still very profitable.

The slave trade to the United States had been prohibited in 1807 but slavery continued in the southern States as the cotton trade grew. The publication of Harriet Beecher�s Uncle Tom�s Cabin in 1852 convinced many of the evils of slavery but Northerners were still reluctant to back a full abolitionist policy. But they did not wish to se slavery spread from the South either and this led to the American Civil War of 1861-65 after the election of Abraham Lincoln as President. Slaves were freed in areas joining the Northern side and in all areas after the 13th Amendment was passed.
3 March 1865. The USA established the Bureau of Freed Slaves, offering them education, medical care, and financial assistance.
