"House of the Dragon," being a prequel to "Game of Thrones," is set in the fictional world of Westeros, which doesn't have a direct equivalent in Earth's history. However, if we were to draw parallels based on technological and societal development, we could make some educated guesses.
The setting of "House of the Dragon" features medieval-style castles, feudal systems, and a lack of advanced technology like gunpowder or industrial machinery. This places it roughly analogous to the High Middle Ages or early Renaissance period in European history, around the 12th to 15th centuries.
However, it's important to note that Westeros also includes elements that don't have real-world equivalents—such as dragons and magic—which complicates direct comparisons. The Targaryen dynasty's rule over Westeros with their dragons might be seen as an era where mythical creatures played a significant role in shaping political power structures.
In terms of relative lore within George R.R. Martin's universe:
- "House of the Dragon" is set about 200 years before the events depicted in "Game of Thrones."
- The timeline includes significant historical events such as Aegon's Conquest (which would be akin to an earlier medieval conquest) and various Targaryen civil wars (like the Dance of Dragons).
So if you want to place it on an Earth-like timeline for fun without overthinking it too much:
- Think late medieval Europe with added fantasy elements.
- Specifically around 1200-1500 AD for general societal structure but with unique fantastical twists.
This gives you a rough idea while still allowing room for all those dragons and magical happenings!
