São Tomé and Príncipe, officially the Democratic Republic of São Tomé and Príncipe, is an island nation in the Gulf of Guinea, off the western equatorial coast of Central Africa. It consists of two archipelagos around the two main islands: São Tomé and Príncipe, located about 140 kilometres (87 miles) apart and about 250 and 225 kilometres (155 and 140 miles), respectively, off the northwestern coast of Gabon.
With a population of 199,910 (2016 Census), São Tomé and Príncipe is the second-smallest African country after Seychelles, as well as the smallest Portuguese-speaking country. Its people are predominantly of African and mestiço descent, with most practising Roman Catholicism. The legacy of Portuguese rule is also visible in the country's culture, customs, and music, which fuse European and African influences.
