São Tomé and Príncipe

São Tomé and Príncipe lie astride the equator in the Gulf of Guinea, and unlike almost every other inhabited land they had no native population: they were entirely uninhabited when Portuguese mariners — by tradition João de Santarém and Pero Escobar — reached them around 1470–1471 in the course of exploring the West African coast. Recognising their value as bases for trade with the mainland, the Portuguese crown set about colonising them under the captaincy (donatário) system, granting the islands to settlers who would develop them on the crown's behalf.

Attracting voluntary settlers to so remote and unhealthy a place proved hard, and the first colonists were largely people the kingdom wished to be rid of. The successful settlement of São Tomé was established in 1493 by Álvaro Caminha, who received the island as a crown grant; Príncipe was settled around 1500. Among the earliest inhabitants were degredados (convicts and exiles) and, in a notorious episode, some two thousand young children taken from Jewish families expelled from Portugal and deported to the island to be raised as Christians, most of whom perished. From this forced mixture, together with enslaved and later freed Africans, the islands' Creole society would grow.

The settlers found the volcanic soil and equatorial climate ideal for sugar cane, and within a few decades the Portuguese had created on São Tomé one of the first plantation economies built on enslaved African labour. Captives were brought from the nearby mainland — the Kingdom of Kongo and the Niger Delta region — to clear forest, plant cane and work the mills. This sugar-and-slavery model, pioneered here on a previously empty island, would later be carried across the Atlantic to Brazil and the Caribbean, where it reshaped the history of the Americas.

Through the sixteenth century sugar made São Tomé rich. The island became Africa's foremost sugar exporter and, for a brief period, was reckoned among the world's largest producers; the number of mills grew from a handful in the 1510s to some sixty by 1550. At the same time the islands served as a major entrepôt of the transatlantic slave trade: captives shipped from the mainland were gathered, held and transhipped at São Tomé before being sent on to Europe, the Atlantic islands, the Spanish Caribbean and Brazil. The crown took the islands under direct administration — São Tomé in 1522, Príncipe later in the century — as their strategic and commercial value grew.

Slavery on the plantations was brutal, and resistance was constant. From early in the colony's life enslaved people escaped into the forested, mountainous interior, where they formed independent maroon communities; the most enduring were the Angolares, of disputed origin — held either to descend from survivors of a shipwrecked slave ship around the mid-sixteenth century or from runaways of the plantations — who settled the rugged south and lived largely by fishing, rejecting plantation labour. These free communities of the interior repeatedly raided the estates.

The greatest uprising came in 1595, when a leader remembered as Rei Amador (Amador Vieira), associated with the Angolares, united maroons and plantation slaves in a general revolt against Portuguese rule. Beginning on 9 July 1595, his forces — said to have numbered in the thousands — overran much of the island and burned plantations, and for a time controlled most of São Tomé before the Portuguese regrouped. Amador was captured and executed early in 1596, but he endured in memory as a hero of resistance and is today honoured as a national figure. Sugar, meanwhile, was already failing: competition from Brazil, the poor quality of the islands' product, slave revolts and a destructive Dutch sack of São Tomé in 1641 left the plantation economy in long decline, and the islands subsisted thereafter largely as a slave-trade transit point.

Figures of the era

For more than a century after sugar's collapse the islands languished as a way-station of the slave trade. Revival came with new crops: coffee was introduced in the early nineteenth century and cocoa (cacao) around the 1820s, brought from Brazil. Both flourished in the rich volcanic soil, and great plantations — the roças — spread across the best land, owned by Portuguese companies and absentee landlords and run by managers with near-total authority over the workforce. By the early twentieth century São Tomé and Príncipe had become, for a time, the world's leading producer of cocoa, the islands' defining crop ever since.

Portugal abolished slavery in its empire by stages in the nineteenth century, with an abolition decree of 1869 and full emancipation completed in the 1870s. In practice, the plantations replaced enslaved labour with the serviçais system: African workers, brought above all from Angola and Mozambique under nominal contracts, in reality coerced, retained against their will and rarely returned home. The death rate was appalling. These conditions amounted, in the words of contemporaries, to slavery in all but name.

The system became an international scandal in the early 1900s. The British journalist Henry Nevinson, after travelling through Angola and São Tomé, exposed the traffic in his 1906 book A Modern Slavery, reporting that roughly one in five workers died each year. The Quaker chocolate firm Cadbury — a major buyer of São Tomé cocoa — sent the investigator Joseph Burtt, whose report confirmed the abuses, and in 1909 Cadbury, Fry and Rowntree announced a boycott of São Tomé cocoa. The affair shamed the Portuguese regime and prompted reforms, but coerced labour on the islands persisted for decades, and the buyers shifted much of their sourcing to the British Gold Coast (modern Ghana).

The colonial order rested on a deep social and racial hierarchy, and the Forros — the Creole descendants of freed slaves, whose name comes from the carta de alforria, the letter of manumission — guarded their status as free islanders and refused field labour. In early 1953 rumours spread that the administration under Governor Carlos Gorgulho meant to compel Forros into contract work on the plantations. Resistance and unrest were met with savage repression: on and after 3 February 1953, colonial police, white settlers and some armed labourers killed many Forros in what became known as the Batepá massacre. The exact toll is uncertain — accounts speak of hundreds dead — and the regime long suppressed discussion of it.

Batepá became the symbolic founding moment of São Toméan nationalism. Occurring before the colonial wars elsewhere in Portuguese Africa, it laid bare the violence of the colonial system and lived on in memory and oral history, commemorated each 3 February. As nationalist movements spread across Africa, exiled São Toméans drew on this memory to organise. The independence struggle came to be led by the Movement for the Liberation of São Tomé and Príncipe (MLSTP), founded in exile and based for a time in Gabon, with Manuel Pinto da Costa among its leaders.

Decolonisation arrived through events in Lisbon. The Carnation Revolution of 25 April 1974 overthrew Portugal's dictatorship, and the new government committed to giving up the overseas colonies. Late in 1974 Portuguese and MLSTP representatives met to arrange the transfer of power, recognising the MLSTP as the islands' representative. A transitional government followed, and on 12 July 1975 São Tomé and Príncipe became an independent state, with Manuel Pinto da Costa as its first president.

Figures of the era

The new republic took a radical course. Under the constitution promulgated in December 1975 the MLSTP became the sole legal party, and Pinto da Costa built a one-party socialist state aligned with the Eastern bloc, nationalising the cocoa plantations and the economy. But the roças, deprived of capital and skilled management after the Portuguese exodus, declined steeply, cocoa output fell, and the small island economy grew ever more dependent on foreign aid. By the 1980s economic failure was driving change.

Liberalisation begun in the mid-1980s culminated in 1990, when São Tomé and Príncipe became one of the first African states to abandon one-party rule. A new constitution introducing multiparty democracy and limiting the president to two terms was approved by referendum in August 1990, and free elections followed in 1991. Miguel Trovoada, a former prime minister returning from exile, was elected president as an independent, and power has since alternated peacefully between parties. The early democratic decades saw recurrent political instability, including a short-lived military coup in 2003 that was quickly reversed through negotiation.

Modern São Tomé and Príncipe is the smallest Portuguese-speaking country and the second-smallest in Africa, a parliamentary democracy whose economy still rests heavily on cocoa, fishing, tourism and external support. Hopes that offshore oil in the Gulf of Guinea would transform its fortunes have so far gone largely unrealised. Manuel Pinto da Costa, the founding president, returned to office through the ballot box from 2011 to 2016; subsequent presidents have included Evaristo Carvalho and, from 2021, Carlos Vila Nova — a record of orderly, contested elections that has made the islands one of the more stable democracies in the region.
