I'm interested in below university level education, particularly the equivalent of American high school. Any SubSaharan African country will do, though if specificity is needed then I'd prefer either Kenya, Nigeria, or South Africa.
The South African curriculum for Grade 7-9 Social Science (history and geography) can be downloaded here; the content of the history part is described starting from page 33 (PDF page 38). The curriculum for Grade 10-12 History is here; the content starts at page 13 (PDF page 18).
edit: and Grade 4-6 is here.
