This morning over breakfast, I watched Part 1 (of 2) of this programme, through BBC I-Player. The second part is showing tonight.
A very interesting programme, he talks about the Indian Army then the Tirailleurs Senegalais and how both were affected by European 19th century racial concepts. I would quibble with some of the detail but, on the whole, I recommend this programme. David Olusoga is new to me but he made some really interesting points.
