Building a lasting family legacy has never been more rewarding than with the Dynasty system in The Sims 4 Royalty & Legacy. Whether you want to create a powerful noble house, a mysterious occult bloodline, or simply track your family's achievements across generations, Dynasties give you the tools to make it happen. You can invite relatives from other households, set heirs, forge alliances with rival families, and watch your Prestige grow as members follow your chosen values.
What Exactly Is a Dynasty?
A Dynasty is a formal family organization that any household can create. You do not need royal status or noble titles to start one. Any family, from humble beginnings to established wealth, can form a Dynasty and begin building their legacy.
The Dynasty system tracks your family's values, skills, and achievements across multiple generations. As members follow the established ideals, your Dynasty gains Prestige, which unlocks powerful perks and reward traits for future generations.

How Do You Create and Manage a Dynasty?
Starting Your Dynasty
Open the Dynasty panel and establish your family organization. The Head of the Dynasty (your founding Sim) chooses the initial values and skills that define what your family stands for. These can be changed later, though some members may react negatively if new values conflict with their personal traits.
Adding Members to Your Dynasty
Membership follows strict family rules. You can only add Sims who are related by blood or marriage. This includes:
- Direct family members (parents, children, grandparents, grandchildren)
- Siblings and extended relatives
- Spouses and in-laws
- Adopted family members
Children can join any Dynasty started by their direct family members. When a baby is born to parents from different Dynasties, you choose which Dynasty they join at birth.
Cross-Household Membership
Dynasty membership is not restricted by household, world, or career. Family members living in different neighborhoods or even different worlds can all belong to the same Dynasty. This lets you build sprawling family networks across your entire save.

How Does the Prestige System Work?
Prestige represents your Dynasty's accumulated influence and accomplishments. As members perform actions aligned with your chosen values, Prestige increases. Each Prestige level grants points you can spend on Dynasty Perks.
Dynasty Values and Ideals
Values determine which activities boost your Prestige. The system covers base game content and cross-play from all eligible expansion packs. Your ideals can encourage or discourage specific:
- Careers and career actions
- Skills and skill-building activities
- Extracurriculars and hobbies
- Social interactions and relationship types
Dynasty Perks and Reward Traits
Spend your Prestige points on perks that benefit your entire family. Some perks grant reward traits that allow your children to inherit mental, physical, social, or creative boosts. These inherited advantages give future generations a head start.
How Do You Manage Heirs and Succession?
Designating Your Heir
The heir position must be manually chosen by the player. Any Dynasty member can be set as heir, including children born out of wedlock. The designation is not permanent, so you can change your heir whenever circumstances shift.
Challenging for Leadership
Dynasty members who want power have options beyond waiting patiently:
- Ask or Extort: Members can request the heir position or use blackmail to force the Head's hand
- Challenge: Sims with specific values can challenge the Head through Chess Matches, Duels, or physical fights
- Usurp: Any member ranked higher than the current Head can simply take the position

What Are Scandals and How Do They Work?
The Scandal system operates independently from Dynasties. Any Sim can have secrets, be extorted, or expose others, regardless of Dynasty membership.
Discovering Secrets
Your Sims can uncover dirt on others through multiple methods:
- Ask mutual acquaintances about the target Sim
- Dig through trash for evidence
- Hack for secrets using computers
- Explore secret passageways
- Consult the enchanted mirror
- Purchase information from the Info Broker website
Using Secrets Against Others
Once you discover a secret, you have options:
Secret Children and Parentage
When a Sim gives birth, you can choose who the "official" father is from a dropdown menu. If this differs from the biological father, a Secret Baby relationship is created. The family tree shows different information depending on who views it. Sims who know the truth see both connections, while others only see what they "know."

How Do Dynasty Alliances Work?
Only Dynasty Heads can forge alliances with other Dynasty Heads. Alliances create formal connections between families without requiring marriage or blood ties. When two Dynasty members do marry, you have the option to merge both Dynasties into a new one, which starts with a Prestige boost based on both original families.
Matchmaking Within Dynasties
Dynasty Heads can "Encourage to Court" specific Sims, playing matchmaker for their members. Results are not guaranteed, and romantic plans may not always succeed.
Can Occults Join Dynasties?
Absolutely. The developers specifically designed the system to welcome all occult types. Vampires, Spellcasters, Werewolves, Mermaids, and other supernatural Sims are fully eligible for Dynasty membership.
The Mysterious value is dedicated entirely to occult families. Vampire Offspring relationships are specifically coded as eligible for Dynasty membership, ensuring supernatural bloodlines can thrive.
Does This Work With Existing Saves?
Yes. The Dynasty system is fully retroactive. You can create Dynasties using families from saves that are years old. The developers specifically tested this feature with a 10-year-old save file to ensure compatibility.
What Family Tree Improvements Are Included?
The family tree received significant upgrades:
- More Sims visible vertically and horizontally
- New relationship categories (stepfamily, half-siblings with proper tags)
- Portrait frames that change based on royal rank
- Special icons showing power dynamics (leader, heir, outcast)
- Adoption display settings you can customize
Key Takeaways for Dynasty Success
Building a powerful Dynasty requires strategic thinking across generations. Choose values that match your playstyle, recruit family members from across your save, and use the Prestige system to unlock advantages for future generations. Whether you pursue noble titles or remain influential commoners, your Dynasty can shape the world according to your vision.
