What was one of the main reasons for the popularity of African slavery?

it was because of the sugar revolution in Europe.Sugar cultivation is quite labor intensive, and indentured servants were insufficient to meet the demand for labor. Additionally, the life expectancy of a servant or slave on sugar plantations was quite short; as a result there was a continual demand for slaves to replace those who died. So great was the demand that several stock companies, including the Royal African Company, were organized to engage in the Caribbean slave trade for profit.  Many slaves in Colonial America, particularly in South Carolina, arrived by way of the Caribbean islands.

Explanation:

So the sugar market in Europe was the primary reason for the transport of African slaves to the Caribbean.

the caste system in india is the paradigmatic ethnographic example of caste. it has origins in ancient india, and was transformed by various ruling elites in medieval, early-modern, and modern india, especially the mughal empire and the british raj.it is today the basis of educational and job reservations in india.it consists of two different concepts, varna and jati, which may be regarded as different levels of analysis of this system.

the caste system as it exists today is thought to be the result of developments during the collapse of the mughal era and the british colonial regime in india. the collapse of the mughal era saw the rise of powerful men who associated themselves with kings, priests and ascetics, affirming the regal and martial form of the caste ideal, and it also reshaped many apparently casteless social groups into differentiated caste communities.the british raj furthered this development, making rigid caste organisation a central mechanism of administration
