Who was the lowest social class of Spanish colonial society and were the slaves and workers?

The lowest social class of Spanish colonial society was comprised of enslaved individuals and indigenous peoples, often referred to as "indiOS." Enslaved Africans were also part of this group, experiencing severe oppression and exploitation. Both groups were subjected to harsh labor conditions and had little to no rights within the colonial system. Their status as the lowest class reflected the broader societal hierarchy based on race and ethnicity during the colonial period.
