The Easter Rising of 1916 was the most significant event in modern Irish history, yet most accounts I have come across up to now have been fairly biased either for or against the rebels. This is an excellent and objective history of the events of the Rising, with a detailed analysis of the background, the key personalities and the evolution of the main ideas of the time, which I found fascinating.
Townshend meticulously assesses the value and truthfulness of various sources he cites, and the confusing picture he paints of the planning of the Rising reflects the realities of the time. The last chapter is an insightful analysis of the legacy of the Rising and the disputes over its meaning by later generations, as well as an attempt to put it in an international context.
The only criticisms I have are that he deals quite quickly with the executions of the leaders, although he does discuss the impact of them, and his writing style is less fluid than some other historians. If you are looking for an easy read, Tim Pat Coogan's account might suit you better, although it's not as detailed.
Regardless of your political views, this is a great book which certainly gave me a better understanding of how modern Ireland was created.
