Tongas

Population: Tens of thousands across both islands; the term marks origin rather than a formal census category

Location: The old roça estates of São Tomé and Príncipe, particularly Água Izé, Rio do Ouro (Agostinho Neto) and Porto Real

Language: Português dos Tongas, a distinctive local Portuguese, alongside Forro and Cabo Verdean Kriolu in mixed households

Language family: Portuguese with Bantu and creole influence

Traditional governance: Estate authority until nationalisation in 1975, then state farms, then partial redistribution; Tonga communities have organised over land title and housing on the former roças ever since.

Most African peoples are federations of named sub-groups (clans, sections, chiefdoms or sub-tribes), each with its own dialect, territory and traditions.

Clothing: Working dress of the estate; the socopé and ússua dance traditions carry costume that borrows from both Portuguese ballroom and continental African forms.

Food: Estate rations transformed into a cuisine: maize, beans, dried fish, banana and palm oil, with calulu shared across island society.

Ceremonies: Socopé and ússua dances; saint days at the roça chapels; funerals in which continental African burial custom persisted longest.

Marriage customs: Consensual union widespread, in part because the estate system discouraged and complicated formal marriage; strong intermarriage between the recruited nationalities.

Initiation rites: None formalised; entry into estate work at adolescence was the practical passage, and land claims after 1975 the modern equivalent.

Every dish the Atlas publishes for São Tomé and Príncipe, at national rather than community level — 9 in all: the staple a household eats daily, the dish the country names as its own, street food, what is cooked for a wedding or Eid, regional specialities and a drink. Quantities and method are given for every one, so these are recipes rather than descriptions, and each has a photograph from Wikimedia Commons. The Food page carries the whole continent, searchable by country and by ingredient.

“The roça bell rings for everyone but the owner.”

Estate labour, described from inside.

“Born here, but the land has another name.”

The Tonga land question in a sentence.

“The dance we brought is the one thing they could not take.”

Culture as retained property.

Creation: Catholic cosmology as taught on the estates, layered over Angolan and Mozambican understandings of ancestors and of witchcraft brought by the recruited generations.

Beliefs: Catholicism; belief in witchcraft and in protective medicine; the dead of the estate cemeteries as a present community, since most workers were never repatriated.

Ancestors: Estate cemeteries hold generations who died without returning; commemoration there is simultaneously family memory and political statement.

Traditional settlements: The sanzala labour lines of the roças — long terraces of single rooms, now inhabited by descendants as permanent housing, often without title.

Building techniques: Colonial masonry with tiled roofs, built for durability and surveillance; the great estate houses, hospitals, chapels and drying terraces around a central courtyard.

Village layout: Owner's house on high ground, hospital and chapel below, labour lines arranged for supervision, drying yards and rail sidings at the centre — an industrial plan now serving as a village.
