Game of Thrones is set in a fictional world inspired by late antiquity and the early Middle Ages, with the narrative opening roughly 17 years before the events of the television series. The primary storyline begins around 298 AL (After Landing), a timeline convention used in the books and shows to mark events relative to Aegon’s Conquest of Westeros. The show’s first season corresponds to this late-Third Century AL period, drawing stylistic and political inspiration from sources as varied as the Byzantine Empire, the Hundred Years’ War, and the Wars of the Roses. The following breakdown clarifies the fictional chronology, its anchors in real history, and why these distinctions matter for understanding the series’ long-form storytelling.
Timeline anchors in the books and show
Both George R. R. Martin’s books and the television adaptation use a shared timeline framework that orients audiences through key events. Important eras include the Dawn Age, the First Men and the Children of the Forest, the Andal invasion, and, centrally, Aegon’s Conquest, which establishes the primary calendar system. The period most viewers recognize begins with the arrival of the royal party in King’s Landing and the murder of Jon Arryn, placing the story at a precise point in the fictional timeline. These anchors allow the narrative to reference past wars, distant legends, and multi-generational grudges that shape character motivations and political stakes.
Key eras in Westerosi history
- The Dawn Age: mythic era of the First Men and the Children, magic and the builders of the Wall.
- The Andal Invasion: introduces the Faith of the Seven and reshapes culture and governance.
- The Targaryen Conquest (Aegon’s Landing): calendar starting point, unifies six of the Seven Kingdoms.
- The Dance of the Dragons: civil war that informs succession fears in the present timeline.
- The Century of Blood: aftermath of the Doom of Valyria, expansion across the known world.
Historical inspirations and parallels
While Westeros is fictional, Martin draws heavily from Eurasian history between late antiquity and the early modern period. The political fragmentation, feudal obligations, and religious schisms echo elements of the Byzantine Empire, medieval Western Europe, and the Mongol invasions of the Middle East. These parallels are most evident in the design of houses, the function of small councils, and the shifting balance of power between throne, faith, and regional warlords. Recognizing these references helps audiences distinguish invented cultures from real-world analogues and understand why certain institutions feel both familiar and fantastical.
How the show timeline relates to the books
The television series covers material primarily from the first book, A Game of Thrones, and extends into later seasons with original content not yet published in the source material. Book timelines are generally more detailed, offering insight into events occurring offscreen or referenced through dialogue and history lessons. The show condenses time, alters pacing, and sometimes reorders events for dramatic impact, but the broad sequence of wars, councils, and coronations remains consistent. Understanding this helps viewers track discrepancies and anticipate where the two narratives may diverge further as the series progresses beyond published books.

Why timeline clarity matters for viewers
A coherent grasp of when Game of Thrones takes place reduces confusion around lineage, inheritance claims, and strategic decisions made by rulers. It clarifies which grudges are decades old and which alliances are freshly negotiated, which helps explain otherwise abrupt character shifts or political pivots. For analysts, creators, and long-form fans, timeline awareness supports deeper engagement with themes of memory, legacy, and the cyclical nature of history that Martin and the showrunners emphasize. Treating the setting as both a historical stage and a narrative device enriches interpretation of symbols, prophecies, and governing structures.
Common misunderstandings clarified
Some viewers assume the series is strictly medieval or directly tied to Earth history, but Martin’s world is an alternate planet with its own geography and rules, albeit heavily informed by historical patterns. Others believe the timeline is explicitly year-by-year mapped, whereas in practice the internal chronology is flexible, especially across continents where information is incomplete. Clarifying these points protects against misinformation and preserves the richness of the fictional universe without imposing real-world constraints that were never intended.
Bottom line on the timeline
Game of Thrones is set in a stylized past resembling late medieval and early classical eras, beginning around 298 AL with the events of Season 1. The timeline is anchored by Aegon’s Conquest and punctuated by reference to older wars and legends that inform present conflicts. While certain details remain ambiguous or debated among fans, the core chronology is consistent within the aired material and the published books. Understanding this framework supports richer viewing, more accurate speculation, and a durable appreciation of the series’ long-form storytelling craft.
