History of HIV/AIDS
Open-knowledge reference entry

AIDS is caused by a human immunodeficiency virus (HIV), which originated in non-human primates
in Central and West Africa. While various sub-groups of the virus acquired human infectivity at different times, the present pandemic had its origins in the emergence of one specific strain – HIV-1 subgroup M – in Léopoldville in the Belgian Congo in the 1920s.
“History of HIV/AIDS” enters the record as open-knowledge reference entry. Crown Archives preserves that source wording while asking what History, AIDS and Open-knowledge can confirm, complicate or overturn.
Why this record matters
“History of HIV/AIDS” is worth following because a concise public description often conceals a longer documentary argument. Here, History, AIDS and Open-knowledge provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 25, 2026.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
