Human slavery - 23 facts not taught in schools

Watch this video to learn of facts about the slavery not taught in schools. The facts are mostly about the African slave trade but not exclusively: 22 facts relate to white slave owners and 1 to 'Arab' slave owners, showing that slavery is not only perpetrated by whites.

1 Treating humans as a commodity, i.e., people denied human rights, and placing a value on them based on their ability to make a profit - so the most valuable slaves were 25-year old black men, followed by child-rearing black women.
2 Using slaves without their consent, for human experiments - rather like those by Nazis on Jews
3 How Africans themselves sold Africans into slavery.  Search for 'James Marion Sims' to learn of his inhumane experiments on slaves.
4 How slaves were forced to breed so the slave population increased so increasing productivity and profits for slave owners
5 How slaves who were free or who had escaped through the Underground Network, were captured and re-sold into slavery by the Reverse Underground Network.  White laws did not allow blacks to testify against whites, so blacks could not make their legal case for freedom.
6 How slaves were branded, just like branding cows, for identification
7 The breeding of savage dogs to capture runaway slaves
8 The Zong mass killing in which ship's captain, Zong, murdered 132 slaves in order to make a claim on an insurance policy for their lost "cargo" (the slaves).
9 How a black man who had been an 'indentured servant' and after that ended he bought himself, a black man (John Kaser) for life. Indentured servitude is not slavery, but owning a person for life is closer to, if not actually being, slavery.
10 Slave owners and missionaries used the Slave Bible to justify slavery, to indoctrinate slaves to become christians, and to suppress slave rebellion and to convince slaves that slavery was acceptable and normal.
11 Branding slaves who attempted to escape slavery as being mentally ill (suffering from Drapetomania); claiming certain (fake) diseases and illnesses were only suffered by slaves or negroes; that blacks were mentally inferior to whites and they were naturally suited to servitude, and that slavery was their only route to happiness.  A guy called Samuel Cartwright was "Professor of Diseases of the Negro" Another of Cartwright's fake diseases afflicting slaves was laziness.
12 Convict leasing aka slavery.  After slavery was abolished, many blacks were unemployed. 
13 Unemployed blacks to be convicted for being unemployed.  As convicts, they were leased out to businesses and forced to perform hard labour, i.e., they were treated as slaves.
14 Millions of Africans were enslaved AFTER the abolition of the slave trade, i.e., the trade continued internationally.
15 Slaves' accommodation was inhumane, causing them physical and psychological suffering.
16 Specific laws (slave codes) were designed to prevent slave rebellion and the perpetuation of slavery of blacks generation after generation.
17 The US domestic slave trade began with the abolition of importation by the US of slaves.  That ban had the unintended consequence of forcing the separation of slave family members - because whites wanted to send them elsewhere to work as slaves, because slaves from overseas were no longer available.  Slave family members were under the constant fear that their family would be separated at any moment.
18 The Underground Railroad was an escape network made up of people committed to freeing slaves.  It  helped 100K slaves escape in a period of 40 years in the early 1800s. An analogy would be the network to help Jews escape the Nazis.
19 American slaves were slaves in urban settings not only plantations, and were forced to work in may trades, many involving skills.  They contributed to the econoic development and prosperity of cities, but without the benefits.
20 Slaves did rebel, for ex, the Haitian Revolution of the 1700s which ended French slavery and created the country today known as Haiti.  10% of sea voyages of slaves involved a rebellion by the slaves.  The rebellion led by Nat Turner (a slave) triggered debate over slavery, tightened the grip of whites over slaves, and resulted in savage reprisals by whites.
21 The East African slave trade (aka Arab slave trade) continued long after the whites abolished slavery - although as noted, whites' abolishment of slavery did not end immediately in practical terms.  The EA slave trade proves slavery was a global disease afflicting supremacists who were not only white-skinned.
22 The 'Middle Passage' refers to the inhumane conditions aboard slave ships transferring slaves to their destinations where they'd work as slaves.
23 Slavery has not ended; it is a reality for 50 million people across the world, many of them children: 'modern slavery' exists under different names: forced marriage, forced labour, and human trafficking
