Primary Timeline and Setting
House of the Dragon takes place roughly 172 years before the events of Game of Thrones, in the world of Westeros around 112–113 AC (After Conquest). The series focuses on the Targaryen dynasty during a period of relative stability and growing tension, long before the fall of the dragons and the War of the Five Kings shown in the main series. Its earliest events occur near King Viserys I’s reign, with the dance of the dragons unfolding in the mid‑120s AC.
Key Historical Reference Points
To understand when House of the Dragon is set, it helps to anchor it to known dates in the show’s lore. The series begins before the Doom of Valyria and well before Robert’s Rebellion or the fall of House Targaryen. The timeline places it more than a century and a half prior to the timeline of the original series, making it a prequel focused on the peak of Targaryen power.
Comparison With Game of Thrones Timeline
The original Game of Thrones series is set around 298–300 AC. By mapping that forward, House of the Dragon sits near the middle of the thousand-year history of the Targaryens in Westeros, closer to their zenith than to their downfall. The following table summarizes the relationship between key milestones.
| Event | Approximate Year (AC) | Context |
|---|---|---|
| House of the Dragon begins | c. 112–113 AC | Viserys I rules; succession tensions build |
| Dance of the Dragons | c. 129–131 AC | Major civil war among Targaryens |
| Game of Thrones timeline | c. 298–300 AC | Westeros during the main series |
| Doom of Valyria | c. ~100 BC | Cataclysm that breaks Valyria (Before AC) |
Setting Within Targaryen History
At the time House of the Dragon is set, the Targaryens have ruled from Dragonstone for roughly 150 years after Aegon’s Conquest. Dragon数量 is still strong, and the Iron Throne is relatively secure. The series explores the fragile peace among the great houses and the dragons’ pivotal role in maintaining order. It precedes the decline of dragon numbers and the fractures that will lead to open civil war later in the century.
Narrative Purpose of the Time Period
Placing the story around 112–113 AC allows the show to examine the political mechanics of succession, legacy, and power while dragons are still a prevailing force. It uses a era of apparent stability to build dramatic tension, foreshadowing the eventual decline. This setting helps viewers understand the origins of conflicts that echo through later generations, linking the Targaryen saga across centuries.

The politics, bloodlines, and dragon lore established here ripple forward in time, informing the backgrounds of houses, characters, and customs viewers later encounter.
