A Modern Slavery, written by Henry Woodd Nevinson and first published in 1906, is a historical account that investigates the ongoing practice of slavery in the Portuguese territories of West Africa, particularly Angola and the islands of São Tomé and Príncipe. Nevinson details his journey to these regions in 1905, revealing the exploitation and human rights abuses associated with the cocoa trade. His work prompted major chocolate companies to boycott cocoa from São Tomé, highlighting the intersection of colonialism and human suffering in the pursuit of profit.
