I watched a documentary on the history channel about a month or two ago on the Easter Rebellion in Northern Ireland. This documentary painted Eamon DeVelera in a negative light, saying basically that he was somewhat of an appeaser when it came to negotiating for Irish independence. It suggested that he was willing to forego the Irish demand for absolute independence in exchange for an end to the hostilities. However, this was not the case. In fact Sinn Fein and the cabinet chosen to present Irish demands were evenly split on the subject of swearing an oath of allegiance to the the King and accepting the fact that while independent, Irishmen would still be subjects of the King. And Eamon DeVelera voted against the oath and refused to consider himself a subject. In response to the split, DeVelera stepped down as President of Sinn Fein, and formed his own party, Fianna Fail, whose aims included a republican Ireland, a restoration of the Irish Language, a development of Irish culture, a development of an equal opportunity social system, a just distribution of land in Ireland and the general independence of the country.
Just goes to show you, the "history" shown on the history channel isn't all its cracked up to be.
