With the aid of Eugene O'Growney (author "Simple Lessons in Irish") Eoin MacNeill, Thomas O'Neill Russell and others, the League was launched in the wake of an address Hyde delivered to the Irish National Literary Society, on 25 November 1892: ‘"The Necessity for De-Anglicising Ireland’". Citing Guiseppe Mazzini (the Italian nationalist who had been the inspiration for the rare language enthusiast among the Young Irelanders, Thomas Davis), Hyde argued that "in Anglicising ourselves wholesale we have thrown away with a light heart the best claim we have to nationality".
