 The careers of some 1930s writers continued after World War Two, including those of Gwyn Thomas, Vernon Watkins, and Dylan Thomas, whose most famous work "Under Milk Wood" was first broadcast in 1954.Thomas was one of the most notable and popular Welsh writers of the 20th century and one of the most innovative poets of his time.The attitude of the post-war generation of Welsh writers in English towards Wales differs from the previous generation, in that they were more sympathetic to Welsh nationalism and to the Welsh language.
