House Targaryen is the focus of House of the Dragon and the most historically detailed family in the Game of Thrones universe, with fascinating lore to dive into. The two HBO adaptations depict House Targaryen at vastly different points in its prominence in Westeros. House of the Dragon, which is based on the book Fire & Blood by George R.R. Martin, examines the noble family at the peak of its power, with the Targaryen dynasty being the dominant force in the Seven Kingdoms due to their growing reign of dragon power.

200 years later, Game of Thrones sees the Targaryen family after its fall, beginning with Viserys and Daenerys being the exiled remnants of an overthrown rule, with the new Baratheon lineage sitting the throne. The journey from House of the Dragon’s events to those in Game of Thrones is filled with fascinating stories, with the dynasty’s grasp on the realm continuously wavering more and more. Not to mention, there are years of history prior to House of the Dragon, some of which should be shown in future Game of Thrones spinoffs.
