The term used for Jews who converted to Catholicism to avoid persecution during the Inquisition is "conversos," or sometimes referred to as "Marranos." These individuals often faced intense scrutiny and suspicion from both the Spanish Inquisition and their communities, as many continued to practice Judaism in secret.
As for the Taíno, who were indigenous peoples of the Caribbean, their conversion to Christianity was often coerced by European colonizers. In some cases, practices similar to those of conversos occurred, where indigenous peoples adopted Catholicism outwardly to avoid persecution or violence, while maintaining aspects of their traditional beliefs and practices in private.
This forced conversion and the cultural syncretism that followed created complex identities wherein both conversos among Jews and indigenous peoples like the Taíno grappled with the expectations of their new religions while trying to preserve their original cultural and religious identities.
