Had Germany declined to grab Tanzania, Rwanda, and Burundi in 1884-1885 and Britain grabbed these territories instead, could we have seen Britain eventually combine these colonies together with Kenya and Uganda in order to create an early version of the East African Federation?
Basically, I am thinking of a colonial merger similar to what Britain did with Northern Nigeria and Southern Nigeria in 1914 in our TL.
Also, how would Kenya, Uganda, Tanzania, Rwanda, and Burundi develop as one colony? Would they be better off and more prosperous in this TL?
In addition to this, how does this TL's East African Federation look like after independence? Does it descend into civil war and/or break up? Or does it become a massive success?
Any thoughts on this?
