@livinglava,
No, in fact, slavery has never been racist. To take the example of slavery in the West Indies, Columbus asked Isabella, after his first voyage, if he could enslave the aboriginals. She told him no, that if they accepted Christianity, they could not be enslaved, and if they did not accept Christianity, they were limbs of Satan and must be destroyed. That they might not have understood the difference between peonage and slavery is a moot point--a great deal of the population of Europe were still serfs/peons, and only economic considerations were "liberating" them. The serfs in Russia were not liberated until 1861. The Romans enslaved anyone who resisted them in arms past a certain point (the nuances of Roman policy are to be found in Machiavelli's
Discourses on the First Ten Books of Titus Livius). The populations of the province of Africa (roughly, modern Tunisia and parts of Libya and Algeria), Magna Graecia (the Greek colonies of southern Italy), parts of Cisalpine Gaul (northern Italy) and parts of Iberia were all sold into slavery for resisting in arms. Octavian, known as Caesar Augustus, staffed his civil service with Greek slaves, because they were uniformly literate. The slave populations of those areas listed above were used in the
latifundia, huge slave driven "ranches" which produced grain, wine, olive oil, wool cloth and pottery. Eventually, the small holders and small craftsmen of what we call Italy were driven out of business, and ended up in the cities on welfare. They could find casual labor in construction (nobody with an ounce of sense employs slaves to build the roof over their heads). The state provided
panem et circenses--bread and circuses--to keep the free population contented. Eventually, about the only customer for the goods the wealthy patricians produced on their
latifundia was the empire itself. It eventually destroyed the economy of the western portion of the empire, leading to the collapse of imperial authority in the west in the fifth century. It was a good thing that Constantine had divided the empire between east and west--the eastern portion, which was not hag-ridden by slavery, lasted another thousand years, until it finally fell to the Turks in 1453.
The Turks used slaves intensively. Many of their finest troops were slaves from the Caucasus Mountians--at the time, Caucasians had a reputation as fierce warriors. The Mamluks (from an Arabic word meaning property, and slave when applied to people) eventually took over Egypt in the 13th century, and controlled it until Napoleon's invasion in 1798. Of course, after 500 years in Egypt, they no longer looked very white.
It was common for the Norse, the Danes, the Svear (Swedes), the Angles and the Saxons to enslave men captured in war, and women and children taken in conquest. Nothing about slavery in the history of Europe had anything to do with race.
Slavery came to North America with the sugar plantations in the West Indies, which were originally run with white labor, indentured workers. But they couldn't handle the climate, and malaria killed them off pretty quickly (the Spanish unwittingly brought malaria to the Americas) . Eventually, they settled on west African slaves, because of their resistance to malaria (due to endemic sickle cell anemia--but I wont'go into that here). A Dutch captain who had been driven off course in the middle passage eventually fetched up at Jamestown in 1609 and tried to sell some of his human cargo. No one was interested--they had trouble enough feeding themselves. So, on a high tide one night, he left his least eligible slaves behind, and sailed away. Sheer humanity lead the Jamestown colonists to feed them. Blacks became the slave of choice because they could handle the climate and the malaria (which also quickly became endemic in the American south--tens of thousands of soldiers in the American civil war on both sides died from it). The British encouraged settlers in the southern colonies to buy slaves because it was a way of maximizing the profits from their sugar island plantations. When the British claim that they ended slavery in the 1830s, they're not being quite truthful. They ended black African slavery. They replaced them with coolie labor from India--illiterate villagers who put their mark on a contract of indenture, and became slaves by default just as Africans had two centuries earlier.
Slavery was the disease of the ancient European and middle eastern world (read your bible sometime). It has never been about race--it has always been about greed and the will to dominate. You need to read almost a lifetime's worth of history before you comment on a topic as broad and deep as slavery.
