This is a very well written, very wide ranging history of Irish Nationalism that treats it as a complex subject worthy of detailed analyis.
The author, greatly to his credit, does not attempt to hide the worst features of British rule, even though he ultimately comes down as pro-partition, at least in the sense that he clearly believes that some form of partition was inevitable by 1912. Nor does he over-simplify complex issues, or regard Nationalism as homogenous and unchanging as many other appear to. At the end of this book I felt I had learned an awful lot about the belieefs of Irish Unionists & Nationists, and a lot of the "why?" too.
It's not always an easy read, but repays the effort. It's not perefect - I would have liked more on the Curragh mutiny and the 1920's Boundary Commisison, for example - but no book on such a contentious subject ever will be, so it deserves five stars.
