**Liam O'Callaghan's revelatory Blood and Thunder shows that the rise of Irish rugby is inextricable from the tensions, debates and divisions – of politics, religion and class – that have defined modern Irish history.**Despite the political partition of the island, Ireland competes at rugby internationally with an all-island team – and with a bespoke anthem that nobody loves but everyone tolerates. Ireland has become a leading rugby nation despite its tiny population and the fact that the sport is only the fourth most popular team game on the island by participation.

In* Blood and Thunder *, O’Callaghan traces the dramatic evolution whereby a rugby nation that was deeply attached to amateurism has made such a dramatic success of professionalism. From the sequence of events that led Ireland's private Catholic secondary schools to embrace rugby, to the controversies and crises that have shaken Irish rugby – including the Northern Troubles, the Belfast rape trial, and the rising toll of head injuries – Blood and Thunder tells the rich and fascinating story of Irish rugby.

Blood and Thunder is more than a social and political history of Irish rugby. It is also a shadow-history of modern Ireland, rooted in brilliant original research and packed with terrific stories.
