The Manifesto of the Irish Volunteers was composed by MacNeill, with some minimal changes added by Tom Kettle and other members of the Provisional Committee. It stated that the organisation's objectives were "to secure and maintain the rights and liberties common to the whole people of Ireland", and that membership was open to all Irishmen "without distinction of creed, politics or social grade." Though the "rights and liberties" were never defined, nor the means by which they would be obtained, the IRB in the Fenian tradition construed the term to mean the maintenance of the rights of Ireland to national independence and to secure that right in arms.
