Geoffrey Chaucer  was an English writer, poet, and public servant, widely regarded as the "father of English literature." Born in London during the Middle Ages, Chaucer is best known for his masterpiece The Canterbury Tales, a collection of stories that offers a vivid and diverse portrayal of English society at the time. His decision to write in Middle English, rather than Latin or French, was groundbreaking and helped elevate the status of English as a legitimate literary language. In addition to his literary endeavors, Chaucer had a successful career in public service. He held various positions, including Controller of Customs for the Port of London and Member of Parliament. His close observation of people across different social classes-gained through both his official duties and personal experiences-informed the complex character portrayals and social commentary found in The Canterbury Tales. Written in verse, this work brings together a group of pilgrims traveling to the shrine of Saint Thomas Becket in Canterbury, each telling a tale along the way. Chaucer's work marked a turning point in English literature, showing that English could be a powerful and expressive literary medium. His style blended humor, realism, and deep psychological observation. He was one of the first writers to portray characters from all walks of life with nuance and humanity, paving the way for the development of literary realism in later centuries. Chaucer influenced countless writers, including William Shakespeare and T.S. Eliot. His ability to merge entertainment with sharp social commentary made his work not only a literary achievement but also a valuable historical document of medieval culture and values.
