Welsh literature encompasses the body of written works produced in Wales and by Welsh authors. It includes a rich tradition of poetry, prose, and drama, often reflecting the unique culture, history, and language of Wales. The earliest examples date back to the Medieval period, with notable works in Old Welsh. The literature is characterized by its use of the Welsh language and themes of identity, nature, and folklore. Prominent figures include Dylan Thomas, known for his lyrical poetry, and R.S. Thomas, who explored spirituality and the Welsh landscape. Today, Welsh literature continues to thrive in both Welsh and English.
