Crusader Kings II (CK2) is not just a game—it’s a grand strategy RPG hybrid that lets you shape the fate of a dynasty through centuries of history. Known for its complex mechanics and intricate storytelling, CK2 offers a deep, immersive experience that rewards strategy and careful planning. Whether you’re expanding your kingdom or scheming to overthrow rivals, there’s always something to learn.

Benjamin Pearce, a well-regarded CK2 guide creator, has developed detailed how-to guides that help both new players and seasoned veterans navigate the game’s challenging world. This article explores some of his top gaming strategies and tips to help you conquer medieval Europe, one plot at a time.

1. Getting Started with Crusader Kings II (CK2)

If you’re new to CK2, the sheer scope of the game can be overwhelming. Here’s how to get started on the right foot:

  • Install and Configure: After installing the game, start with the tutorial to familiarize yourself with the UI and controls.
  • Choose a Starting Character: The game offers numerous start dates and dynasties. Beginners should start with a relatively stable realm, like a duke in England or a small kingdom in Ireland.
  • Understand the Objective: The goal isn’t world conquest but ensuring your dynasty survives and thrives. Expand your territory, form alliances, and secure a powerful lineage.

1.1 Essential DLCs to Improve Your CK2 Experience

DLCs can significantly enhance your CK2 experience. Here are the must-have expansions:

  • The Old Gods – Unlocks the ability to play as pagans, offering new mechanics and more aggressive expansion strategies.
  • Way of Life – Adds character focus and detailed role-playing elements that allow for more control over your ruler’s personality.
  • Legacy of Rome – Focuses on the Byzantine Empire and military enhancements like retinues (personal troops).

Optional but useful DLCs include Reaper’s Due (disease and epidemics), Holy Fury (crusades and pagan mechanics), and Sons of Abraham (religious expansion).

2. Character Management and Dynasty Building

In CK2, your character is the core of the game. Managing their traits, relationships, and skills is critical to your success.

  • Traits and Skills: Every character has traits that affect gameplay. Some boost diplomacy or martial prowess, while others can be detrimental (like lunacy or gluttony).
  • Titles and Claims: Ensure your character has a legitimate claim to titles. Fabricating claims is an option, but it may provoke wars.
  • Marriages and Alliances: Marriages are strategic tools in CK2. Use them to secure alliances, gain claims on foreign titles, or improve genetic traits for your heirs.

2.1 Tips for a Strong Heir

Building a strong dynasty starts with securing capable heirs. Here’s how:

  • Educate Your Children: Assign guardians based on the traits and skills you want your heirs to develop. A martial-focused heir is great for warfare, while diplomacy skills are essential for kingdom stability.
  • Choose the Right Spouse: Focus on alliances and genetic traits. Marry into families with strong traits like genius, quick, or attractive for better heirs.
  • Prepare for Succession: Ensure your heir has enough support from vassals. Consider changing succession laws to avoid civil wars upon your ruler’s death.

3. Territory Expansion and Warfare

One of the most exciting aspects of CK2 is expanding your realm. However, reckless expansion can lead to your downfall.

  • Casus Belli: Always ensure you have a legitimate reason for war. Use fabricated claims, de jure claims, or holy wars to expand your territory.
  • Army Management: Balance your levies and personal retinues. Ensure your army composition is strong, with enough heavy infantry and cavalry for major battles.
  • Avoid Overextension: Expanding too quickly can destabilize your realm. Always manage newly acquired territories and keep vassals loyal.

3.1 Defensive Strategies

Sometimes, defense is the best offense. Here’s how to protect your realm:

  • Fortify Borders: Upgrade castle fortifications in vulnerable regions.
  • Manage Threat Level: Avoid becoming too powerful too quickly. High threat levels will trigger defensive coalitions against you.
  • Diplomacy as Defense: Form alliances with powerful neighbors to deter potential aggressors.

4. Diplomacy and Alliances

Diplomacy plays a vital role in CK2. Knowing how to manage relationships can make or break your dynasty.

  • Form Alliances: Use marriages and pacts to secure powerful allies.
  • Non-Aggression Pacts: These are helpful for keeping peace while you focus on internal development.
  • Manage Vassals: Keep your vassals happy to prevent rebellion. Grant them titles, gifts, or honorary positions if necessary.

4.1 Avoiding Common Diplomatic Mistakes

  • Don’t Overextend Alliances: Multiple alliances can drag you into wars you can’t win.
  • Be Cautious with Favors: Granting favors may lead to unexpected obligations.
  • Handle Betrayals Carefully: If an ally turns on you, respond decisively to protect your reputation and power.

5. Intrigue, Assassinations, and Plots

Intrigue is one of the most entertaining mechanics in CK2. Sometimes, a dagger in the dark is more effective than an army on the battlefield.

  • Use Plots Wisely: Assassinate rivals, overthrow kings, or eliminate heirs to secure your position.
  • Spy Network: Build a strong spy network to uncover plots against you and strengthen your own schemes.
  • Manage Factions: Dissatisfied vassals will form factions to press their demands. Keep an eye on them and neutralize threats before they grow.

5.1 Avoiding Internal Collapse

  • Monitor Vassal Happiness: Keep an eye on vassal opinions to prevent revolts.
  • Distribute Titles Carefully: Giving too much power to a single vassal can backfire.
  • Use Council Positions Strategically: Appointing powerful vassals to your council can help keep them loyal.

6. Religion and Crusades

Religion in Crusader Kings II is more than just a background detail—it’s a driving force behind alliances, wars, and character behavior. Understanding religious mechanics can significantly impact your game.

  • Major Religions: Catholicism, Orthodoxy, Islam, Paganism, and more—each religion offers unique gameplay elements.
  • Religious Authority: A strong religious authority provides stability and reduces heresy. Weak authority can lead to widespread religious chaos.
  • Conversion Strategies: Converting to another religion can save your dynasty, but it may also destabilize your realm.

6.1 Crusades and Holy Wars

Participating in crusades and holy wars can be a game-changer.

  • Join a Crusade: Crusades provide opportunities to gain vast lands and prestige.
  • Declare Holy Wars: Expand your territory at the expense of neighboring religions. Be careful, though—other realms may rally to defend their faith.
  • Crusade Rewards: If you contribute significantly, you could end up as the new ruler of a massive kingdom.

7. Economy and Realm Management

Maintaining a stable economy is crucial for success in CK2. Without a steady income, you won’t be able to raise armies, build improvements, or fund schemes.

  • Taxation and Revenue: Focus on increasing tax income from cities and improving your capital’s infrastructure.
  • Trade Routes and Cities: If playing as a republic or controlling coastal areas, take advantage of trade routes to boost your economy.
  • Avoid Debt: Being in debt reduces your ruler’s prestige and leaves you vulnerable to enemy attacks and internal plots.

7.1 Building Improvements

Investing in your holdings is essential for long-term growth.

  • Castles: Improve fortifications and barracks for better defense and stronger armies.
  • Cities: Prioritize markets and ports for increased tax revenue.
  • Temples: These are useful for boosting piety and religious authority.

8. Technology and Cultural Advancements

Technology development in CK2 is gradual but can offer significant advantages over time.

  • Three Categories: Military, Economy, and Culture—each one focuses on different aspects of your realm’s development.
  • Spread of Technology: Technology spreads from more advanced regions to nearby areas. Focus on improving your capital to lead the way.
  • Cultural Innovations: Cultural tech helps with legal matters, vassal management, and construction efficiency.

8.1 Focusing on Key Technologies

  • Military Tech: Prioritize heavy infantry and cavalry improvements.
  • Economic Tech: Focus on castle infrastructure for better taxation and troop production.
  • Cultural Tech: Improve legalism to unlock better succession laws and manage larger realms.

9. Succession Laws and Inheritance

Succession is one of the most challenging aspects of CK2. Poor planning can lead to civil wars and the fragmentation of your realm.

  • Types of Succession Laws:
    • Gavelkind: Divides your realm among all male heirs, often causing instability.
    • Primogeniture: The eldest son inherits everything—more stable but harder to achieve.
    • Elective Monarchy: Vassals vote on the next ruler, offering both flexibility and risk.
  • Changing Succession Laws: Requires a stable realm and high crown authority. Ensure your vassals support the change.

9.1 Preventing Succession Crises

  • Secure Strong Heirs: Focus on educating your heir and building their skills.
  • Manage Claims: Watch out for ambitious family members with claims on your titles.
  • Appease Vassals: Keep powerful vassals happy to prevent rebellions during transitions.

10. Advanced Tips and Tricks for Long-Term Success

Mastering CK2 takes time, but these advanced strategies will give you an edge.

  • Roleplay Your Character: Embrace your character’s traits to create a more immersive experience.
  • Alternate Game Styles: Try different start dates or play as unique characters like Byzantine emperors or Norse pagans.
  • Adapt and Improvise: CK2 is unpredictable—expect the unexpected and be ready to adjust your plans.

10.1 Common Mistakes to Avoid

  • Ignoring Vassal Opinions: Always monitor vassal loyalty.
  • Expanding Too Fast: Manage new territories carefully to avoid revolts.
  • Neglecting Alliances: Never underestimate the power of a strong alliance.
