Aestheticism and Decadence in Victorian fiction challenged societal norms, emphasizing beauty and art for art's sake. These movements emerged as reactions to the era's utilitarian attitudes, exploring themes of moral decay, excess, and refined sensibilities. Key figures like Oscar Wilde and Walter Pater shaped these literary movements, influencing art, fashion, and culture. Their works questioned traditional morality and gender roles, leaving a lasting impact on modernist literature and contemporary popular culture.
