Today, 75 years after the party's formation, and following many years struggling to develop from an intellectual pressure group, Plaid Cymru is now the official Opposition in the National Assembly for Wales, runs three local authorities and has two Euro-MPs. The eminent historian John Davies traces the origins of Plaid Cymru in the 1920s and describes its growth through the twentieth century to its current position as Wales' second party. Plaid Cymru: The History of the National Party of Wales will be the ideal introduction to the party's policies and personalities, both for activists and the general reader.
