Showing São Tome: Journey to the Abyss--Portugal's Stolen Children by Paul D. Cohn

In 1485 the Portuguese Crown and Catholic Church began to kidnap Jewish children, forcibly convert the young conscripts, and ship them to São Tomé Island off the African equator to work the government sugar plantations. The collision of slavery, sugar agriculture, and discovery of The Americas transformed this island colony into the nidus of the wholesale black slave trade that infected Africa and Western commerce for the next 350 years. Sao Tome reveals the Medieval Church's complicity in the business of human bondage.
This little-known chapter of the Diaspora tells the story of young Marcel Saulo and his sister Leah abducted with other children from their synagogue in Lisbon and shipped by caravel 4,000 miles to the West-African island where they bear witness to the holocaust of African slavery. This is a historical novel that chronicles one man's courageous struggle against religious and racial persecution, torture, and disease, and explores the abyss of Inquisition, Portuguese and Spanish world expansion, and the blight of slavery fueled by the calamitous growth of sugar commerce.
