A Knight of the Seven Kingdoms is set about 100 years before the events of Game of Thrones in the official HBO/Game of Thrones timeline.

Where it sits in the timeline

  • The story takes place roughly a century before the start of the main Game of Thrones TV series.
  • It is also said to be around 72 years after the events of House of the Dragon.
  • So, in order: House of the Dragon → A Knight of the Seven Kingdoms → Game of Thrones.

In-universe context

  • The show follows Ser Duncan the Tall (Dunk) and his young squire Aegon “Egg” Targaryen , wandering Westeros during a relatively more peaceful but tense prelude to later conflicts.
  • Politically, it’s the Targaryen era but long before the fall of the dynasty seen in Game of Thrones , so many families, sigils, and places you know exist, just in an earlier generation.

Quick numeric answer

If you’re just looking for the “how long before” part in one line:

A Knight of the Seven Kingdoms is set about one century before Game of Thrones in the canon TV timeline.

TL;DR: Think of it as a prequel that’s ~100 years earlier than Game of Thrones and between House of the Dragon and Game of Thrones in the overall saga.
