    The history of the great poet, T.Gwynn Jones (1871-1949)

    Review of the Welsh language biography ‘Byd Gwynn’ by Alan Llwyd

    We have good reason to be grateful to the poet and author Alan Llwyd, who was brought up in the Llŷn peninsula and now lives in Morriston.  His awdl, a poem in strict metres on the subject Llif (stream, or flow) ensured that  the chair could be awarded this year, providing a real climax for the successful Llŷn and Eifionydd National Eisteddfod.

    By now Alan Llwyd has established himself as one of Wales’ outstanding poets and writers.  His output is astonishing, both in quality and quantity , and includes a number of detailed biographies of Welsh poets, among them T. Gwynn Jones.

    Today people remember T. Gwynn Jones as one of the leading poets of the twentieth century but he was much more – for decades a ...

  • Saunders Lewis, Wales and Europe by Dafydd Wigley

    The next three years will be crucially important for refining a model of independence relevant for Wales in today’s world.  In the wake of Brexit, Wales needs to protect its essential connection with the continent of Europe – the source of our values and civilisation, and the context of practical independence for our country. 

    Nearly a century ago, the Plaid Cymru leader Saunders Lewis set out a vision of Wales in Europe.  The Plaid Cymru History Society is proud to publish in full the important lecture delivered by Dafydd Wigley during the 2023 Eisteddfod Llŷn ac Eifionydd National Eisteddfod – which shows that this vision is today more relevant than ever.  

    Saunders Lewis, Wales and Europe

    [In Memory of Emrys Bennett Owen,
    who opened my eyes to his vision]


    I am grateful to the Eisteddfod for being for this forum to re-examine ideas that are highly ...

  • Penyberth – New Research on Old Bailey Switch

    New research reveals that the controversial transfer of the Penyberth Bombing School trial from Wales to London was engineered by a local police chief rather than the Westminster government.

    Three of the Plaid Cymru’s leading members, Saunders Lewis, Lewis Valentine and DJ Williams were imprisoned following the burning of the bombing school under construction at Penyberth near Pwllheli in September 1936.

    The move of the trial to the Old Bailey came after a jury in Caernarfon had failed to find the Three guilty of committing the damage and caused a major furore in Wales.  Former Prime Minster David Lloyd George was one of many who blamed the government of the day – “They crumple when tackled by Mussolini and Hitler, but they take it out on the smallest country in the realm,” he said, “This is the First Government that has tried Wales at the Old Bailey.”

    Now freshly published research by ...
