Sinn Féin (newspaper) Sinn Féin (newspaper) Sinn Féin was a weekly Irish nationalist newspaper edited by the Dublin typesetter, journalist and political thinker Arthur Griffith. It was published by the Sinn Féin Printing & Publishing Company Ltd. (SFPP) between 1906 and 1914, and replaced an earlier newspaper called the "United Irishman" which was liquidated after a libel suit. The SFPP brought out the "Sinn Féin Daily" in 1909 but had to abandon it when it plunged the company into enormous debt. The "Sinn Féin" weekly and the SFPP both came to an end when they were suppressed by the British Government in 1914.
