In the middle of the 19th century, the kingdom of Congo, in northern Angola, lived on the slave trade, but Portugal was being pressured by diplomatic partners to extinguish that trade, wrote the historian and journalist Xavier de Figueiredo.
The visit of D. Nicolau to Lisbon, with the furor it generated at the time, was the last diplomatic attempt by the Angolan kingdom, which ended up also determining its extinction, having been completely absorbed by the colonial power.
The book "Príncipe do Congo", by publisher Guerra e Paz, portrays the biography of the Angolan nobleman, in a "journalistic and historical" record, explained the author.
"The 'Prince of Congo' has to do with a key period of what was the colonial history of Angola" and addresses the life of a "person who appears and has an action that deserves to be told for its unusualness", he stressed.
Until then, the entire colonial economy in Angola "had something to do with the slave trade", in a "monoeconomics", which can be comparable to the current dependence on oil.
After the end of the slave trade, "it moved to a diversified economy, based on mines, fisheries, agriculture", explained the author, who also lamented the lack of attention of Portuguese public opinion to African issues.
