"The Portuguese explorer, Fernão do Pó, seeking a route to India, is credited with having discovered the island of Bioko in 1471."

"He called it Formosa ('beautiful [isle]', a name later applied to Taiwan), but it quickly took on the name of its European discoverer, albeit spelt 'Fernando Po.' The islands of Fernando Po and Annobón were colonized by the Portuguese in 1474.... From 1827 to 1843, Britain established a base on the island to combat the slave trade."
