I've always been fascinated by Arthur Balfour. At school, I learned that he was the Conservative PM who lost in the 1906 landslide defeat to the Liberals; later, I learned that he was the Balfour of the 1917 'Balfour Declaration' where the western powers infamously directed the Jews to a homeland in Palestine.
He's also a past Captain of a golf club I'm a member of, and that prompted me to wonder what skills did this man possess that even put him into these positions of power in the first place. Unlike Trump, he wasn't especially rich, although he did have wealthy connections. I'd done a little research previously, but I decided that it was about time I made a conscious effort to find out. Ewen Green's Balfour, from the British Prime Ministers series, was an inexpensive way to begin.
I learned enough from this book about Balfour to feel I understood much better what he had to offer. Also, this was a Kindle edition, and to my surprise it "ended" 75% of the way through – the rest is references. That's good – the book is properly researched and referenced.
