Which author is known for the phrase "Vanity Fair" as a critique of early 19th century Britain?

The phrase "Vanity Fair" originates from William Makepeace Thackeray's novel of the same name, published in 1848. Thackeray uses "Vanity Fair" as a metaphor for the self-indulgent and morally questionable society of early 19th-century Britain. The novel itself is a satirical portrayal of the lives of its characters as they navigate social class, vanity, and the pursuit of wealth and status.

Thackeray's keen observations and wit allow him to critique the superficial values and behaviors prevalent in society during his time. This aligns with the themes of vanity and the often misguided ambitions of people chasing societal approval, making "Vanity Fair" a significant commentary on the era. The novel illustrates how society's norms and values can distort personal integrity and genuine relationships.

Other authors mentioned, such as Charles Dickens and Jane Austen, have also critiqued society in their works, but they do so with different focuses and styles. Dickens's narratives often center on social injustices and class disparities, while Austen emphasizes romantic entanglements and personal virtue within her critiques of gentry and marriage. George Eliot, known for exploring moral complexity and psychological depth, tackles issues of faith, society, and personal ambition. However
