Game of Thrones and House of the Dragon can sometimes feel uninviting to new viewers. Both shows, set in George R.R. Martin's fictional land of Westeros, are dense with details, characters, politics, and histories. With so much going on and so many things for fans to keep up with, it can be hard to keep the full timeline of events straight. The timeline of Westeros is not only limited to the timeline of the two shows--which themselves are set almost 200 years apart--but has a full history that stretches back thousands of years.
