The independence of São Tomé and Príncipe ended five centuries of Portuguese rule and handed over to the State the governance of a territory marked by plantations, forced labor, and economic concentration. The proclamation of July 12, 1975, resulted from anti-colonial resistance and the fall of the Portuguese dictatorship.

Fifty-one years later, the flag, the Constitution, and the national institutions confirm a sovereignty that no serious interpretation can diminish. However, the capacity to decide remains limited by a small, insular economy that depends on foreign countries for food, fuel, equipment, medicine, and financial resources.

The gap between legal freedom and material autonomy permeates daily life. The trade deficit remains deep, the productive sector offers few alternatives, electricity remains vulnerable, and many young people seek employment abroad that the islands cannot guarantee. Each crisis exposes this gap.

Independence must therefore be remembered as an achievement and examined as an incomplete process. The question does not lie in the validity of sovereignty, but in the conditions for transforming national power into economic security, demographic stability, administrative capacity, collective confidence, and resilience to external shocks.

The independence of São Tomé and Príncipe did not begin with the 1975 ceremony. Its memory is intertwined with colonial violence, plantations, and the Batepá massacre, which occurred in February 1953. The repression against African workers and communities became a point of reference for national consciousness and revealed that the colonial order depended on force, racial inequality, and discipline imposed on the land.

In the plantations, the production of sugar, coffee, and cocoa organized the territory and society. Wealth flowed from the islands while labor fell upon populations subjected to coercive regimes. Even after the abolition of slavery, indentured labor contracts maintained the exploitation that affected São Toméans and workers brought from Angola, Mozambique, and Cape Verde.

The Movement for the Liberation of São Tomé and Príncipe (MLSTP) brought together this memory in a political project. After the fall of the Portuguese dictatorship, delegations from the MLSTP and Portugal negotiated in Algiers, between November 23 and 26, 1974, the timetable for decolonization, the Transitional Government, and the definitive transfer of sovereignty to the new State.

The agreement set July 12, 1975, as the date for the proclamation and provided for an Assembly with sovereign constituent powers. Manuel Pinto da Costa became the first President of the Republic in a single-party system. The new power sought to break with the inherited structures, but began governing with few qualified personnel and an administration still dependent on colonial routines.

The nationalization of the plantations responded to the desire to return the land to the country. However, the State received aging properties, a concentrated economy, and almost no room to replace the colonial market.

Remembering the anti-colonial struggle requires acknowledging this reality: independence restored to the people of São Tomé and Príncipe authority over history, but it did not undo, in a single moment, the fragilities accumulated over centuries.

Cocoa occupies a central place in the economic and cultural history of São Tomé and Príncipe. At the beginning of the 20th century, the archipelago led the world in cocoa production. This apparent prosperity was based on large plantations, land appropriation, and a labor system whose violence was inscribed in the buildings, landscapes, and family memories.

When independence arrived, the sector was already showing signs of decline. The departure of Portuguese owners and technicians exacerbated the disorganization of the plantations. Centralized management, soil degradation, lack of investment, and fluctuations in international prices reduced production, deprived the State of revenue, and left many farms without the maintenance necessary to sustain regular harvests.

The failure cannot be explained solely by decisions made after 1975. The colonial economy was designed to export one raw material and import almost everything else. It had not developed a diversified industry, a robust domestic market, or a broad network of technical skills.

The country thus inherited a production structure incapable of guaranteeing food and financial autonomy. Cocoa retains economic and symbolic value. Cooperatives, organic certification, fair trade, and local processing seek to increase producers' income.

In 2024, the cocoa agroforestry system was recognized as a global agricultural heritage by the FAO, for combining cultivation with bananas, breadfruit, matabala (a type of palm tree), and shade trees that protect the soil, water, and biodiversity. The plantations are also repositories of sovereignty. Some remain inhabited in precarious conditions, others have been abandoned, and others host tourism projects.

The debate about its future involves ownership, housing, conservation, and the memory of forced labor. Recovering them requires recognizing who produced the wealth, ensuring rights for the inhabitants, and preventing the agricultural heritage from becoming merely a backdrop.

Economic vulnerability is clearly evident in the trade of goods. In 2024, São Tomé and Príncipe imported goods valued at approximately US$153 million and exported approximately US$29 million. The deficit of US$124 million shows that external sales covered less than one-fifth of purchases and maintained a high and persistent need for foreign currency, aid, and credit.

Insularity increases the costs of transport, energy and supplies. Imported fuels affect electricity, public services, business activity and the state budget.

When foreign reserves dwindle or payments are delayed, financial difficulties quickly translate into energy cuts, shortages, and higher prices for essential products in stores and markets.

The crisis in the electricity sector exposed this chain of events. The public water and electricity company accumulated debts to the national fuel supplier, while the latter lost preferential conditions for purchasing fuel on credit. In 2023, the fuel bill increased by $13 million, and the central bank lost more than a quarter of its gross international reserves.

The small market size limits production on a large scale, but it alone does not explain the fragility. Agriculture has lost capacity, fishing remains underdeveloped, and local processing remains limited.

Tourism generates revenue and employment, especially in Príncipe, although it depends on regular air links, foreign investment, and imports destined for hotels, restaurants, and visitors.

International cooperation has funded roads, schools, hospitals, energy, and social programs that the national budget could hardly support. This support has enabled real progress, but public investments remain subject to the schedules and conditions of the partners.

For an archipelago, autonomy requires external relations underpinned by internal capacity: greater food production, diversified exports, lower electricity losses, and essential services financed by regular and predictable national revenues.

In São Tomé and Príncipe, emigration has become one of the most visible responses to the lack of jobs and prospects. Almost one in five São Toméans, nearly 40 people, live abroad.

Portugal receives about half of the diaspora, while Angola and Gabon maintain long-established communities. Departures have increased since the pandemic and are increasingly dominated by young people of working age.

The migration provides income, training, and protection to many citizens, but the remittances recorded are smaller than the size of the diaspora might suggest. In 2022, formal inflows totaled $7,7 million, equivalent to 1,4 percent of the gross domestic product. This figure had fallen by more than 70 percent since 2014.

The money sent helps pay for food, health, education, housing, and small economic activities. However, 56,9 percent of senders use informal channels for regular family support, and the cost of formal services exceeds the regional average. The poorest families receive fewer transfers, but depend on them to a greater extent to maintain consumption.

Money doesn't eliminate the human cost. Children are left in the care of grandparents or siblings, childcare is divided over long distances, and services lose skilled workers. Prolonged absences alter emotional bonds, cultural transmission, and the availability of professionals in healthcare, education, and administration. Each departure solves an immediate problem, but it can create another, lasting void.

Island culture accompanies displacement through forro, angolar, lung'ie, music, traditional theatre and cuisine. The diaspora can also provide skills, investment and professional networks, provided it finds transparent institutional channels and institutional trust.

A country that relies on its citizens leaving to alleviate economic pressure risks turning emigration into a silent survival policy.

The 51st anniversary of São Tomé and Príncipe's independence unites a historic victory with an open question. The state has survived, pluralized political life, and preserved an identity built upon African memory, the Portuguese language, national languages, and the Atlantic experience.

Sovereignty remains surrounded by material limitations. Dependence on imports, fuel, international financing, and emigration reduces the capacity to translate political decisions into daily security. Cocoa recalls the colonial export function, and remittances reveal families who still sustain their needs from afar.

Independence retains its significance because it restored to the people of São Tomé the right to decide. Giving economic and social substance to this right requires employment, a stable energy supply, capable institutions, and conditions for the retention of young people. Material autonomy will depend on ongoing decisions that link production, skills development, and the diaspora in a verifiable strategy.
