AHC "Peaceful" 1960's

You'll notice in the chart below that the latter part of the 1950's saw something of a lull in battle deaths per global capita -- a feat in human peace that would not be matched consistently until the 1990's. What would it take for the 1960's to be as relatively "peaceful" -- that is, for no year in that decade to surpass 1954 in battle deaths per person in the world?

I think you you have a bloodier 1950s you can do it, French Victory in Indochina so no America war in Vietnam, a stronger France together with UK and Israel take out Nasser, with Egypt under hand no Six Day War, the US over throws Castro so Cuba doesn't worsen the Portuguese Colonial War and a stronger France in Africa and Israel and the UK stronger in Africa you see that war as a flash in the pan thats what I got.
 
^^Or just avert US involvement in Vietnam -- looks like global casualties shot up after 1965.

That still leaves the spike 1960-61, which FWIG primarily consists of the Congo Crisis...

Congo and the independence of Algeria in 1962. The end of that one was nasty. The rise in the second half of the 1970s (after Vietnam was over) was probably in part because the various messes in Africa.

From how I read the chart, the late 1960's and early part of the 1970's are the worst post 1951 (and certainly worse than the late 1970's). Though that really does seem to be due to a pile on of bloody conflicts on top of Vietnam -- the Nigerian Civil War (1967-70), Indo-Pakistani War (1971), Brundi (1972), etc...
 
Are there records of worldwide battle deaths before the 1940s we could look at?

If there are, I'm not seeing it pop up on a Google search. If it's any help, this was the source of the chart in the OP (via Andrew Sullivan). What I can say, based on Wikipedia, is that WWII killed more persons per people in the world per year* than any conflict in human history, save possibly the An Shun Rebellion.

*taken as a whole, the various invasions from Central Asia have taken similar or greater tolls
