"1916: The Mornings After review: Tim Pat Coogan's arrogant travesty of Irish history
Ireland's 'best known historical writer' utterly fails in this badly researched 'personal perspective' of the Irish century, says Diarmaid Ferriter

By page 20 of this truly dreadful book Tim Pat Coogan has puffed himself up to the extent that he has an important announcement to make: he is publishing a "hitherto unpublished" letter from Patrick Pearse to the Fenian John Devoy in New York, written in August 1914.
"I consider the document to be so important as to merit being published in full," Coogan declares. The problem is that the text of the letter is not previously unpublished. It is an exact copy of the letter that Pearse sent to Devoy's colleague Joseph McGarrity the same day and that was published in full 35 years ago, in Séamas Ó Buachalla's The Letters of PH Pearse.
On the basis of this example and many others Coogan is not remotely interested in looking at what others have written on 20th-century Irish history. He describes this book as a "strongly personal perspective" on Ireland since 1916. But he does not appear interested in context and shows scant regard for evidence. He does not attempt to offer any sustained analysis in relation to the challenges of state building, the meaning of sovereignty, economic and cultural transformations, or comparative perspectives on the evolution of Irish society

There is no indication whatsoever that Coogan has engaged with the abundant archival material relating to the subject matter he pronounces on."
