When did Guy de Maupassant’s writing career become successful?

Guy de Maupassant’s writing career achieved success immediately following the publication of his short story "Boule de suif" ("Ball of Fat").1

Upon its release, he became highly sought after by newspapers, prompting him to leave his position at a ministry to pursue writing full-time. The decade between 1880 and 1890 proved to be a period of remarkable productivity and prosperity for him, during which he published approximately 300 short stories, six novels, three travel books, and a volume of verse. His success as a writer was largely attributed to the lucid purity of his French and the precision of his imagery.1
