Color was never a badge of slavery in the ancient or medieval world, nor has it been in the modern world outside of Christian states. Homer sings of a black man, a "reverend herald"
Of visage solemn, sad, but sable hue,Short, woolly curls, o’erfleeced his bending head, . . .Eurybiates, in whose large soul alone,Ulysses viewed an image of his own.
Greece and Rome had their chief supplies of slaves from Europe and Asia. Egypt enslaved races of all colors, and if there were more blacks than others among her slaves, there were also more blacks among her nobles and Pharaohs, and both facts are explained by her racial origin and geographical position. The fall of Rome led to a cessation of the slave trade, but after a long interval came the white slave trade of the Saracens and Moors, and finally the modern trade in Negroes.
Slavery as it exists universally among primitive people is a system whereby captives in war are put to tasks about the homes and in the fields, thus releasing the warriors for systematic fighting and the women for leisure. Such slavery has been common among all peoples and was wide-spread in Africa. The relative number of African slaves under these conditions was small and the labor not hard; they were members of the family and might and did often rise to high position in the tribe.
Roman Slaves
Remembering that in the fifteenth century there was no great disparity between the civilization of Negroland and that of Europe, what made the striking difference in subsequent development? European civilization, cut off by physical barriers from further incursions of barbaric races, settled more and more to systematic industry and to the domination of one religion; African culture and industries were threatened by powerful barbarians from the west and central regions of the continent and by the Moors in the north, and Islam had only partially converted the leading peoples.
Egyptian Slaves
When, therefore, a demand for workmen arose in America, European exportation was limited by religious ties and economic stability. African exportation was encouraged not simply by the Christian attitude toward heathen, but also by the Moslem enmity toward the unconverted Negroes. Two great modern religions, therefore, agreed at least in the policy of enslaving heathen blacks, while the overthrow of black Askias by the Moors at Tenkadibou brought that economic chaos among the advanced Negro peoples and movement among the more barbarous tribes which proved of prime advantage to the development of a systematic trade in men.

The modern slave trade began with the Mohammedan conquests in Africa, when heathen Negroes were seized to supply the harems, and as soldiers and servants. They were bought from the masters and seized in war, until the growing wealth and luxury of the conquerors demanded larger numbers. Then Negroes from the Egyptian Sudan, Abyssinia, and Zanzibar began to pass into Arabia, Persia, and India in increased numbers. As Negro kingdoms and tribes rose to power they found the slave trade lucrative and natural, since the raids in which slaves were captured were ordinary inter-tribal wars. It was not until the eighteenth and nineteenth centuries that the demand for slaves in Christian lands made slaves the object, and not the incident, of African wars.
Roman Slaves
In Mohammedan countries there were gleams of hope in slavery. In fiction and in truth the black slave had a chance. Once converted to Islam, he became a brother to the best, and the brotherhood of the faith was not the sort of idle lie that Christian slave masters made it. In Arabia black leaders arose like Antar; in India black slaves carved out principalities where their descendants still rule.
Muslim Slaves
Some Negro slaves were brought to Europe by the Spaniards in the fourteenth century, and a small trade was continued by the Portuguese, who conquered territory from the "tawny" Moors of North Africa in the early fifteenth century. Later, after their severe repulse at Al-Kasr-Al-Kabu, the Portuguese began to creep down the west coast in quest of trade.
They reached the River of Gold in 1441, and their story is that their leader seized certain free Moors and the next year exchanged them for ten black slaves, a target of hide, ostrich eggs, and some gold dust. The trade was easily justified on the ground that the Moors were Mohammedans and refused to be converted to Christianity, while heathen Negroes would be better subjects for conversion and stronger laborers. In the next few years a small number of Negroes continued to be imported into Spain and Portugal as servants. We find, for instance, in 1474, that Negro slaves were common in Seville.
There is a letter from Ferdinand and Isabella in the year 1474 to a celebrated Negro, Juan de Valladolid, commonly called the "Negro Count", (El Conde Negro), nominating him to the office of "Mayoral of the Negroes" in Seville. The slaves were apparently treated kindly, allowed to keep their own dances and festivals, and to have their own chief, who represented them in the courts, as against their own masters, and settled their private quarrels.
Between 1455 and 1492 little mention is made of slaves in the trade with Africa. Columbus is said to have suggested Negroes for America, but Ferdinand and Isabella refused. Nevertheless, by 1501, we have the first incidental mention of Negroes going to America in a declaration that Negro slaves "born in the power of Christians were to be allowed to pass to the Indies, and the officers of the royal revenue were to receive the money to be paid for their permits."
Montevideo's colonial district is the birthplace of Uruguay's Candombe music. Africans from the Southern and Western regions (Bantú regions which include Congo, Angola and Mozambique) were brought to Uruguay and Argentina through the slave trade beginning in 1750. "Africans arriving from the Bantú region brought with them the Candombe rhythm," explains Navos. "Being from different nations and regions, they didn't have the possibility of communicating through language."
Within the now-famous address is what historian Philip S. Foner has called "probably the most moving passage in all of Douglass' speeches."
Most favelas are constructed from whatever material the inhabitants can find. The houses are not sturdily built and do not offer much protection from Mother Nature. Electricity is rare and there is no running water.
Some of the older favelas in Rio de Janeiro were originally started as quilombos (independent settlements of fugitive African slaves) among the hilly terrain of the area surrounding Rio, which later grew as slaves were liberated in 1888 with no places to live. It is generally agreed upon that the first favela to be called by this name was created in November 1897. At the time, 20,000 veteran soldiers were brought from the conflict against the settlers of Canudos, in the Eastern province of Bahia, to Rio de Janeiro and left with no place to live.
