This picture’s caption says it is of an Egyptian slavemaster and a female Waswahili (Swahili) slave in Cairo c.1864
Slavery was so widespread throughout history. When I found this picture I’d sat down to read a “brief summary”, which was just silly. We tend to be taught a very limited version of the history of slavery in school (if we’re taught it at all – Australia does an abysmal job of teaching anything other than Anzac Day – and our current government wants to put more emphasis on that moment and little else!).
