The Game of Thrones genealogy chart reveals how family ties drive alliances, betrayals, and wars across the Seven Kingdoms. Understanding these connections helps explain who rules, who resents, and who quietly plots for the throne.
This guide decodes the most important houses, bloodlines, and power shifts through focused sections and a detailed summary table. Use these insights to track loyalties, predict conflicts, and appreciate the layered storytelling of the series.
Key Houses and Major Bloodlines
The central conflict of Game of Thrones revolves around several ancient houses with intertwined ancestry. Stark, Lannister, Baratheon, Targaryen, and Tyrell lineages form the backbone of the genealogy chart, with many minor houses branching from them.
Each house carries symbols, mottos, and histories that shape political marriages, succession disputes, and wartime allegiances. Mapping these links clarifies who stands to gain or lose from every royal decree and battlefield victory.

The Stark Lineage and North Succession
The Stark tree branches through Winterfell across generations, with critical splits between main heirs and younger siblings. Ned’s legacy continues through Robb, Sansa, Arya, Bran, and Rickon, each facing unique dangers and destinies.
Key moments in this bloodline include the disappearance of Rickon, Bran’s mystical path, and Sansa’s evolution from naive girl to ruling lady of the North. The Stark genealogy highlights resilience, loyalty, and adaptation under extreme pressure, shaping the future of the North.
Lannister Power Plays and Incestuous Heritage
Cersei, Jaime, and Tyrion form a complex triangle within House Lannister, bound by blood, ambition, and secrets that define the family’s ruthless reputation. Their intertwined fates influence battles, betrayals, and royal councils throughout the series.
The incestuous heritage and pursuit of absolute power place the Lannisters at the center of many political explosions. Understanding their alliances and rivalries helps explain shifts in the throne room and on the battlefield.
Targaryen Restoration and Dragon Claims
Daenerys Targaryen rebuilds the dynasty from exile, using dragons, foreign armies, and bloodline legitimacy to challenge established rulers. Her claim intersects with Jon Snow, creating a potential union of Stark and Targaryen heritage that reshapes the genealogy chart.
Tracking the surviving Targaryen bloodline clarifies motivations behind the conquest of Westeros and the push for the Iron Throne. The dragons and ancient Valyrian ties amplify fears and hopes across the Seven Kingdoms.
