prequel

A prequel is a work of fiction that takes place before the events of a previously released work in the same narrative universe. It is typically released after the original, and it aims to expand backstory, explain motivations, or reveal how certain conditions or relationships came to be. The term 'prequel' is a blend of 'pre-' and 'sequel' and entered popular use in the late 20th century. While often marketed as a direct continuation of the same story universe, prequels may focus on different characters or eras and are not strictly bound to mirror the original's plot.

Prequels differ from origin stories and flashbacks; some are full narratives that can stand alone, while others are tightly linked to the original's chronology. They can fill in backstory, explore political, social, or historical context, or show how pivotal events shaped the world of the original work.

Common media include film series, standalone films, television spin-offs, novels, and video games. Notable examples include Star Wars Episode I–III, Rogue One: A Star Wars Story, The Hobbit: An Unexpected Journey, and X-Men: First Class.

Reception of prequels varies. They can satisfy curiosity and expand lore, but they risk retconning, diminishing tension, or overreliance on established outcomes. Successful prequels usually balance fresh storytelling with continuity and respect for the source material.
