Innti was an Irish language poetry movement, associated with a journal of the same name founded in 1970 by Michael Davitt, Nuala Ní Dhomhnaill, Gabriel Rosenstock, Louis de Paor and Liam Ó Muirthile.  These writers were students of University College Cork, drawing inspiration from Seán Ó Ríordáin and Seán Ó Riada, as well as American influences such as the Beat movement and counterculture.  Their reception was mixed, with Gaelic-traditionalists resenting their urbanism, social liberalism and Anglo-American influences.
