Trollope is best known for the Chronicles of Barsetshire, a series of six novels set in the fictional cathedral town of Barchester, including The Warden (1855), Barchester Towers (1857), Doctor Thorne (1858), and The Last Chronicle of Barset (1867). These works vividly portray the clergy and gentry of rural England with warmth, humor, and keen social observation. His second great series, the Palliser novels, explores Victorian political life and includes Phineas Finn (1869) and The Eustace Diamonds (1873).
His masterpiece, The Way We Live Now (1875), is a biting satire of greed, fraud, and speculation in Victorian society. Trollope's fiction is admired for its realistic characters, moral complexity, and rich depiction of everyday life. Although his reputation temporarily declined after his posthumous Autobiography revealed his disciplined writing routine, he is now firmly recognized as one of the greatest English novelists.
