Whose centenary is it anyway?

Yesterday’s Sunday Times stirs the centenary stew by claiming that No less than five political parties are to mark the centenary of the Sinn Fein movement this year with rival commemorations – all of them claiming direct descendancy from Arthur Griffith’s version. They even woke Brian Feeney from his post-Christmas slumber, and he, unsurprisingly, throws his weight behind Gerry Adams’ Sinn Féin claim to the celebrations (if not the bill) – but will they wince at him pointing out that Griffith’s original Sinn Féin was not republican. “[the original]Sinn Fein maintained the concept of a dual monarchy for Ireland under the British crown until 1917″?
