Know no uprising in African land (6)
I believe the answer is:
kenyan
'in african land' is the definition.
'know no uprising' is the wordplay.
'know' becomes 'ken' (I've seen this in other clues).
'no' becomes 'nay' (I've seen this before).
'uprising' says the letters should be written backwards.
'nay' back-to-front is 'yan'.
'ken'+'yan'='KENYAN'
(Other definitions for kenyan that I've seen before include "East African" , "Native of Nairobi, perhaps" , "From Mombasa, for example" , "Native of Mombasa, perhaps?" , "Eg, native of Nairobi" .)
