I’m a Kenyan, and I can safely say that the Mau Mau stuff is a bigger deal outside Kenya that it is in Kenya now.
Only a minority of one tribe (albeit the biggest tribe) out of 42 distinct tribes were involved in that.
And the British operations were not pleasant, but hardly extermination and most people now have forgotten about it.
I remember learning about it in Kenya at school and most people just shrugged their shoulders.
What’s happened is that some very smart people have managed to use some of the few remaining survivors to pursue legal cases, and get compensation that is peanuts for the GB government but obviously a shit tonne of money for the individuals involved.
As a Kenyan I am halfway loathe to state this but there is a culture in Kenya of hustling people, and trying to extract money from those richer than you.
It’s part of the big man and our time to eat mentality.
And given the numbers of people killed in the Mau Mau uprising, I’m pretty sure we’ve inflicted worse on ourselves around 1998 and around 2008, during election times.
The threat (and use) of tribal violence is never very far away.
And politics aligns along tribal lines generally.
If you want to investigate further, look up what is happening with Ruto (the vice president, a kalenjin smallish tribe, but in power longest under Moi, generally disliked because Moi pretty much looted the country and got away with it as as part of a power transfer deal) and the rift occuring between him and Kenyatta (president, Kikuyu, largest tribe) and the aligning of Kenyatta and Odinga (head honcho of the Luo, 2nd largest tribe.)
And bear in mind the guys who prosecute humans rights abuses at the Hague tried to get Kenyatta arrested, on account of his incitements to ethnic violence.
So, the 4 or 5 years of relative brutality during Mau Mau is largely forgotten, although the land distribution that occurred under the Brits not so much, although successive governments have done much the same thing so even that isn’t an issue.
Edit:
Whilst browsing the BBC I found this:
Which is pretty indicative of what I am talking about.
