Which of these African countries list "Spanish" as an official language?

Equatorial Guinea is the only African country that lists Spanish as an official language. This is primarily due to the country's historical ties with Spain, as it was a Spanish colony until it gained independence in 1968. The Spanish language has since been maintained as one of the official languages, alongside French and Portuguese. This linguistic influence is also reflected in the country's education system, government documents, and media, making Spanish a significant part of Equatorial Guinea's cultural and administrative fabric.
