In the late 18th century, the American constitution accepted the existence of slavery. It was considered as an institution: there have always been slaves from the 18th. They choose black slaves instead of Indians because of the trial of Valladolid, where people wondered if the Native was a man or simply an animal. It turned to be a theological problem: if the Native did not have a soul then he was an animal. In the end, they declared that Natives had a soul and this "discovery" caused an economic shock: the Natives could not be employed anymore in plantations and ships started bringing in African slaves.
Towards the end of the 18th, people thought slavery would naturally die out. They were very naive. Unfortunately, Whitney invented the Cotton Gin and put an end to those naive considerations. Rather than declining, the number of slaves increased in the South: in 1820, there were 1 500 000 slaves in America. They were 4 000 000 in 1860. Slavery was basically an economic problem for 3/4 of the cotton crops were exported, representing 60% of America"s foreign earnings. Slavery was hence very profitable to the South and -by way of consequence- to the whole continent.
Everybody sees the discrepancy between that democratic system and the harsh realities of slavery, which was a potentially explosive issue. Several stages in the explosion:
- 1800: the slave Gabriel Prosser led an insurrection with 1 000 slaves in Virginia. He was executed, as well as 35 other people.
- 1822: the authorities discovered plans for slave insurrection in South Carolina with slave Vesey trying to launch a slave insurrection.
- 1819-1822: the "black years" following the Missouri Compromise, a 2-year struggle between North and South. After this, there will be free states and slavery states.
After 1820, the USA are divided between free states and pro-slavery states. The balance is impossible. In Louisiana, slavery is allowed in the South but prohibited in the North: controversial gets tougher and tougher and violence slowly but surely rises. That situation turned about sectionalism (from Latin sectus: cut) and there were more and more slaves' insurrections. David Walker, a free black, published Appeal to the Coloured Citizens, urging slaves to rebel/revolt in 1830. His motto was "Kill or be killed !". 1831 knew an insurrection led by Nat Turner in Virginia. Sixty whites were killed.
He was the son of a free slave and moved to Boston in 1829 to sell old clothes. He published a pamphlet and, over the night, his book was a success. It infuriated Southern land owners and Goergia offered a reward of $10 000 for anyone who would deliver Walker alive and $1 000 to kill him. By the summer of 1830, Walker was dead. His point was mainly historical: there was no slavery in history. All the examples he took belonged to his biblical culture, his background being essentially religious (religion: shelter for slaves).
