Queen Nzinga of Ndongo and Matamba

Njinga Mbande — written Nzinga in much English-language material, and baptised Ana de Sousa — ruled Ndongo and then Matamba in what is now Angola through the middle decades of the seventeenth century, and died in 1663. She spent roughly four decades resisting Portuguese expansion inland from Luanda by war, diplomacy and alliance. She also made her kingdom a major intermediary in the Atlantic slave trade. Both of those statements are supported by the evidence, and an account that drops either one is not a simpler version of her life but a different and inaccurate one.

Start with the evidence, because it determines everything else

Nearly every contemporary written source about Njinga was produced by the people fighting her.

The record consists of Portuguese governors' correspondence and military reports, and of accounts by Capuchin missionaries who spent time at her court — most influentially Giovanni Antonio Cavazzi, whose widely circulated work shaped European images of her for centuries and was written with an evangelising purpose. Her own position survives principally through letters she dictated in Portuguese to Portuguese officials, which is to say through the language, scribes and archival conventions of her adversaries. Those colonial records are now catalogued through Portugal's national archival service, whose Digitarq portal provides access to millions of items across the country's archives.

There is no surviving contemporary narrative written from inside her kingdom, in its own language, by someone of her own court. That absence is the single most important fact about this biography, and it should be stated before any anecdote. The general problem — reading a life through people who had reasons to distort it — is set out in how we know what historical figures actually did, and Njinga is one of the sharpest test cases in the whole field.

What the record supports

Portuguese forces had been pushing inland from the coast for decades, taking captives and establishing forts, when Njinga first appears in the record as an envoy: in 1622 she travelled to Luanda to negotiate with the Portuguese governor, and was baptised there as Ana de Sousa. Within a few years she had become the ruler of Ndongo, in contested circumstances that the Portuguese sources describe in hostile terms and that modern historians read carefully against the grain.

Driven from Ndongo by Portuguese campaigns, she established herself in neighbouring Matamba and rebuilt a state there. When the Dutch took Luanda from the Portuguese in 1641 she allied with them; when the Portuguese recovered the port in 1648, she fell back on Matamba and continued the conflict from there, eventually reaching a negotiated settlement in the 1650s that recognised her rule. She died in 1663.

Even this outline is a reconstruction from adversary documents, and the dates that look most solid — 1622, 1641, 1648, 1663 — are the ones anchored to Portuguese administrative events rather than to her own kingdom's record-keeping.

The famous anecdote, and why it is handled with care

The best-known story about Njinga is the chair: that when she arrived to negotiate at Luanda and was offered no seat, so that she would have to stand before the seated governor, she had an attendant kneel and sat on them instead.

It is a superb story about a real political problem — protocol as a means of asserting hierarchy between a colonial official and a sovereign envoy. It is also a story whose surviving tellings come from accounts written decades afterwards, and which circulated in Europe through a famous engraving. Historians generally treat it as evidence of how Njinga was remembered and represented rather than as a documented moment. That distinction — between a source's report and a verified event — is the everyday work described in our guide to primary and secondary sources, and it applies here with unusual force, because the memorable image has largely displaced the documentary record in popular accounts.
