About São Tomé

São Tomé, the capital of São Tomé and Príncipe, sits on São Tomé Island, the larger of the country's two main islands. The city was founded by Portuguese explorers in 1485 on land that was uninhabited before their arrival, there is no pre-colonial indigenous population in the country's recorded history. São Tomé became a major transit point for the Atlantic slave trade, serving as a hub for enslaved Africans transported to Brazil and the Caribbean. The country gained independence from Portugal on 12 July 1975. São Tomé and Príncipe was one of the first African countries to undertake a democratic transition, moving from a single-party Marxist state to a multiparty democracy in 1990. The country operates a semi-presidential system, with the president and prime minister sharing executive authority. São Tomé is a small city of around 80,000 people housing the National Assembly, the presidency, and the principal ministries of one of Africa's smallest and least populous states.

Frequently Asked Questions

  • Was São Tomé and Príncipe always inhabited?

    No. The islands of São Tomé and Príncipe were uninhabited when Portuguese explorers arrived around 1470. There was no indigenous population prior to Portuguese colonisation. The population today is descended from Portuguese colonisers and the enslaved Africans brought to work on sugar plantations, creating a distinct Creole culture and language (Forro).

  • When did São Tomé and Príncipe gain independence?

    São Tomé and Príncipe gained independence from Portugal on 12 July 1975, following Portugal's Carnation Revolution of April 1974, which ended decades of authoritarian rule and began the decolonisation of Portugal's African territories. The country was initially governed as a one-party state by the MLSTP (Liberation Movement of São Tomé and Príncipe).

  • What type of government does São Tomé and Príncipe have?

    São Tomé and Príncipe is a semi-presidential republic, meaning executive power is shared between a directly elected president and a prime minister accountable to the National Assembly. The country transitioned from a Marxist single-party state to a multiparty democratic system in 1990, making it one of Africa's earliest democratic transitions.

  • What role did São Tomé play in the slave trade?

    São Tomé was a central node in the Atlantic slave trade from the late 15th through the 17th centuries. Portuguese colonisers used the island as a transit and processing point for enslaved Africans transported from the West African coast to Portugal, Brazil, and the Caribbean. The island's sugar plantations were among the first in the Atlantic world to use enslaved African labour at scale.

  • Is São Tomé and Príncipe one of Africa's smallest countries?

    Yes. São Tomé and Príncipe is Africa's second smallest country by population, after Seychelles, with approximately 220,000 inhabitants. By area, at 964 square kilometres, it is Africa's second smallest country, also after Seychelles. It is a member of the African Union, the Community of Portuguese Language Countries (CPLP), and the Economic Community of Central African States (ECCAS).

Sights and landmarks

The historic inner city of São Tomé, the Bairro Histórico, contains Portuguese colonial architecture from the 15th and 16th centuries, including the Sé Catedral, one of the oldest churches in sub-Saharan Africa. The Forte de São Sebastião, built in 1575 as a defence against pirate attacks, now houses the national museum with collections on slavery, colonial history and traditional culture. The presidential palace and National Assembly are found in the compact city centre. Outside the city lie abandoned sugar cane plantations, known as roças, which make visible the island's wealth and history of slavery. The neighbouring pristine rainforests and volcanic mountain landscapes make the islands attractive for ecotourism.

Climate and best time to visit

São Tomé has a tropical rainforest climate with high temperatures and rainfall throughout the year, except for a short dry period. The grande seca (great dry season) runs from June to August, the smaller dry period falls in December and January. Outside these periods there is rain almost daily, mainly in the afternoon. Temperatures vary little: 28°C to 32°C by day, 20°C to 24°C at night. Humidity is high all year. The best time to visit is June to August when it is drier, though the sea is rougher then. The southern part of the island receives considerably more rain than the north due to orographic uplift.

Regional significance

São Tomé and Príncipe occupies a distinctive position as the smallest island state in the Gulf of Guinea, surrounded by large oil-producing countries such as Nigeria, Equatorial Guinea and Gabon. The geographic location in the Gulf has given the islands strategic significance in the context of maritime security and oil exploration boundaries. The Joint Development Zone, a shared offshore exploration area with Nigeria, represents the most concrete regional economic cooperation. As a small state, São Tomé has strategically maintained good relations with both Portugal and Brazil, China and the US, alternately attracting international attention and aid.

Economy

São Tomé's economy has traditionally rested on cocoa exports, the basis of the colonial plantation economy. After independence, plantations were nationalised but fell into decline; some have since been privatised and specialised in high-quality organic cocoa for luxury chocolate makers. Tourism is growing as an economic pillar thanks to pristine nature, colonial architecture and a reputation as an exclusive ecotourism destination. Offshore oil reserves have been discovered in the country's exclusive economic zone, but large-scale exploitation has not yet begun. The island state is heavily dependent on foreign aid and imports of basic goods. GDP per capita is low in African terms, but political stability and a democratic reputation attract development cooperation.
