Ronan Huon, who was, along with Pol Le Gourrierec, the editor of Tír na nÓg, took charge of the fusion.
Numerous authors of modern Breton literature, such as Abeozen, Per Denez,[6] Youenn Drezen, Xavier de Langlais (Langleiz), Anjela Duval,[7] Reun Ar C'halan, Maodez Glanndour, Youenn Gwernig, Roparz Hemon, Ronan Huon, Paol Keineg, Kerverzioù, Meavenn, Youenn Olier, and Yann-Ber Piriou have made contributions to the magazine with poems, short stories, essays, and studies.
Breton poets and singers who were directly involved in the revival of the music of Brittany, such as Milig ar Skañv (Glenmor), Youenn Gwernig, or Bernez Tangi, have also published poems and songs in Al Liamm.
As emphasised by Welsh author and editor Meic Stephens, Al Liamm is "the principal platform for just about every Breton writer of note to emerge during the post-war period".
[2] Poems from Al Liamm authors have often been put to music and songs by Breton singers, such as Véronique Autret, Nolwenn Leroy, Yann-Fañch Kemener, Gilles Servat and Alan Stivell.
