In the words of the philosopher Cornel West, Raymond Williams was ‘the last of the great European male revolutionary socialist intellectuals’. A figure of international importance in the fields of cultural criticism and social theory, Williams was also preoccupied throughout his life with the meaning and significance of his Welsh identity. _Who Speaks for Wales?_ (2003) was the first collection of Raymond Williams’s writings on Welsh culture, literature, history and politics. It appeared in the early years of Welsh political devolution and offered a historical and theoretical basis for thinking across the divisions of nationalism and socialism in Welsh thought. This new edition, marking the centenary of Williams’s birth, appears at a very different moment. After the Brexit referendum of 2016, it remains to be seen whether the writings collected in this volume document a vision of a ‘Europe of the peoples and nations’ that was never to be realised, or whether they become foundational texts in the rejuvenation and future fulfilment of that ‘Welsh-European’ vision. Raymond Williams noted that Welsh history testifies to a ‘quite extraordinary process of self-generation and regeneration, from what seemed impossible conditions.’ This Centenary edition was compiled with these words in mind.
