When the habit of selling men began to be restricted to the selling of negroes, companies were formed to organize this business and to have it carried on with economy. The Portuguese had a monopoly of the trade for a long time. They went up and down the African coast, picking quarrels with the natives when the latter did not quarrel enough among themselves to create a suitable supply of captives. Slaves were in great demand in Spain, and quite numerous at Seville. The percentage which the Portuguese exacted induced the Spaniards at length to enter into the traffic, which they did, according to Zunigo, in 1474. At that time negroes were confined, like Jews, to a particular quarter of a Spanish city. They had their places of worship, their own regulations and police. "A _Cedula_ [order] of November 8, 1474, appoints a negro named Juan de Valladolid mayoral of the blacks and mulattoes, free and slaves, in Seville. He had authority to decide in quarrels and regular processes of law, and also to legalize marriages, because, says the _Cedula_, 'it is within our knowledge that you are acquainted with the laws and ordinances.' He became so famous that people called him _El Conde Negro_, The Black Count, and his name was bestowed upon one of the streets of the negro quarter." Thus men were born in Europe into a condition of slavery before 1500. In that year the introduction of negroes into Hayti was authorized, provided they were born in Spain in the houses of Christian masters. Negroes who had been bred in Morisco[9] families were not allowed to be carried thither, from a well-grounded fear that the Moorish hatred had sunk too deeply into a kindred blood. A great many slaves were immediately transported to Hayti; for in 1503, "Ovando, the Governor-General of the Indies, who had received the instructions of 1500, asked the court 'not to send any more negroes to Espanola, because they often escaped to the Indians, taught them bad habits, and could never be retaken.'"
