Etching your name into the continent of Calradia and raising your own banner. "Founding a kingdom" is a dream for every Bannerlord player. However, the path to building an ideal kingdom and unifying the continent is far from smooth. Wars with hostile forces, rebellions in territories, and fickle vassals. The key to overcoming these difficulties is the strategic implementation of "kingdom policies." This article thoroughly explains the optimal policy combinations to maximize Influence efficiency, income, and military power, along with a roadmap from founding your kingdom to unifying the continent.

First Steps to Building a Kingdom

To found your own kingdom, you need to meet certain conditions and follow several steps. Let's start by understanding the basics.

Conditions and Procedure for Kingdom Creation

To found your own unique kingdom, it's common to progress through the main quest "Neretzes's Folly." The conditions and procedure are summarized in the table below.

Solo Kingdom vs. Joining an Existing Kingdom

There are two paths for kingdom management: founding a "solo kingdom" from scratch or joining an existing kingdom as a "vassal." Both have their merits and demerits.

• Solo Kingdom: You can freely decide all policies, and all conquered territories can potentially become yours. However, immediately after founding, you will be seen as an enemy from all directions and forced into tough battles. This is truly a high-risk, high-reward choice.
• Joining an Existing Kingdom: Under the protection of a powerful nation, you can safely acquire territory and wealth. Wars are also conducted collectively, so the individual burden is lighter. However, policy-making power rests with the monarch and influential nobles, and you may be forced to participate in unwanted wars. A playstyle where you first build up strength as a vassal and then declare independence later is also effective.

Optimal Policies for Building the Strongest Kingdom Explained

The foundation of kingdom management lies in "policies." Here, we explain particularly powerful and advisable policies, categorized by objective.

Maximizing Influence Efficiency: Establishing the Foundation of Kingdom Management

Influence is the "currency" for kingdom decision-making, such as raising armies and voting on policies. Ensuring a stable supply of this is the top priority.

• Sacred Majesty: Increases the ruling clan's Influence by +2 daily. With no drawbacks whatsoever, this is the strongest foundational policy that continuously increases the ruler's Influence automatically. Pass it immediately after founding your kingdom.
• Royal Privilege: Similarly increases the ruling clan's Influence by +1 daily. Combined with "Sacred Majesty," you'll gain +3 Influence daily without doing anything.
• Royal Guard: Reduces the Influence cost required to form armies by 30%. Essential if you frequently engage in large-scale wars. It dramatically curbs Influence consumption, allowing you to field more armies.

Strengthening Military Power: The Source of Dominating the Continent

In Bannerlord, military strength is justice. Policies that increase **party (use 'warband' or 'party' contextually)** size will give you an advantage in any battle.

• Royal Guards: Increases the ruling clan's **party (use 'warband' or 'party' contextually)** size by +80. Since the player's **party (use 'warband' or 'party' contextually)** is directly strengthened, the benefits are immense. This is also one of the policies you should prioritize adopting immediately after founding your kingdom.
• Noble Retinues: Increases the **party (use 'warband' or 'party' contextually)** size of all clans belonging to the kingdom according to their Clan Tier (a +10 increase per Tier 1). This is a very powerful policy that boosts the military strength of the entire kingdom, significantly improving war-fighting capability.
• Militia Recruitment: Reduces Garrison wages by 20%. As you acquire many territories, the maintenance cost for Garrisons becomes enormous. This policy stabilizes finances and allows more soldiers to be allocated for defense.
• Castle Charters: Reduces castle upgrade costs by 20%. With no downsides, it streamlines territory development, making it a useful policy that never goes to waste, regardless of when it's adopted.

Maximizing Income and Stabilizing Territories: Key to Wealth and Military Strength

A rich treasury supports a powerful army. Policies that increase income and maintain territorial stability are also important.

• Land Tax: Increases tax revenue from villages owned by the ruler by 5%. A subtle but steadily income-boosting policy.
• Debased Currency: Provides an additional 100 Denar daily from cities owned by the ruler. While a strong direct income boost, it comes with the drawback of -1 Loyalty for the city. Consider adopting this only in stable cities with no risk of rebellion.
• Debt Forgiveness / Tribunes: These policies increase Loyalty by +2 and +1 respectively. Especially immediately after conquering territories of a different culture, Loyalty can plummet, increasing the risk of rebellion. Temporarily securing Loyalty with these policies to prevent rebellions is extremely important. However, since they impose a production penalty, it's standard practice to switch to other policies once the territory stabilizes.

Optimal Policy Combinations and Recommended Order by Situation and Objective

The priority of policies to adopt changes depending on the kingdom's situation. Here, we introduce recommended models tailored to the kingdom's growth phases.

Phase 1: Dictatorial Moves Immediately After Founding

Immediately after founding, in many cases, only the player's clan, the ruler, belongs to the kingdom. This is a golden time when you can pass any policy 100% without opposition. Don't miss this opportunity and prioritize enacting the following policies that bring immense benefits to the ruler:

1. Sacred Majesty (+2 Influence/day)
2. Royal Guards (+80 Party Size)
3. Royal Privilege (+1 Influence/day)
4. Castle Charters (-20% Castle Upgrade Cost)

Phase 2: Stabilization Measures During Territory Expansion

This is the phase where you expand your territory by adding other clans as vassals. Especially when conquering territories of different cultures, Loyalty issues become severe. To prevent rebellions, we strongly recommend adopting the following policies temporarily:

• Debt Forgiveness (+2 Loyalty/day)
• Tribunes (+1 Loyalty/day)

Maintain positive Loyalty with these policies, and once the territory stabilizes through the governor's skills and building effects, switch to other permanent policies.

Phase 3: National System During Stability and War

This is the stage where your kingdom is stable, and you launch large-scale wars aiming for continent unification. The goal here is a tried-and-true combination supported by many players.

[Versatile Optimal Combination]

• Sacred Majesty (Influence+)
• Royal Guards (Ruler **party (use 'warband' or 'party' contextually)** Size+)
• Noble Retinues (All Parties+)
• Castle Charters (Development Efficiency+)

These four policies have almost no drawbacks and permanently strengthen the core of kingdom management. Using these as a foundation, it is ideal to customize them according to your kingdom's style, such as adding "Royal Guard" if you frequently form armies, or "Land Tax" if you want to further strengthen your finances.

Territory and Vassal Management for Smooth Kingdom Operation

Beyond policies, daily territory management and relationships with vassals are also essential for the stability of your kingdom.

Prioritizing Fief Acquisition and Tips for Vassal Management

1. Secure your own territories: After conquering new territory, a vote will occur to decide who receives it. If you wish to own it yourself, always put your name forward as a candidate and use your abundant Influence to acquire it. The more direct holdings the ruler has, the more stable the nation's power.
2. Reward your vassals: To increase the number of vassals, it's standard practice to recruit nobles with high Honor or Mercy / Cruelty traits. To maintain their Loyalty, it's important to regularly grant them territories (especially those of their original culture) and keep relations good. Clans without territory will accumulate discontent and eventually defect.
3. Push through policies with Influence: As other clans increase, dissenting opinions may arise in policy votes. However, the ruler can use Influence to push through their own decisions. Use the Influence gained from policies like "Sacred Majesty" to guide your kingdom in the right direction.

Efficient Methods for Gaining and Spending Influence

• Gaining Methods: The most efficient way is to defeat enemy armies and capture their lords as Prisoners. Additionally, donating soldiers or Prisoners to the kingdom and automatic increases from policies like "Sacred Majesty" and "Royal Privilege" are also important.
• Spending Methods: The main uses are "forming armies" and "decision-making in policy votes." Especially when forming large armies, a significant amount of Influence is consumed, so the presence or absence of "Royal Guard" greatly impacts your ability to sustain warfare.

Conclusion

Kingdom management in Mount & Blade II: Bannerlord is truly a continuous series of strategies and decisions. The optimal policy combinations and recommended order introduced in this article should serve as your compass. First, leverage the golden time immediately after founding to strengthen yourself as the ruler, then thoroughly manage Loyalty during the territory expansion phase, and finally transition to a tried-and-true setup that boosts the overall national power and military strength of the kingdom during the stability phase. While adhering to this basic flow, flexibly customizing policies according to your kingdom's culture and playstyle will be the most certain path to unifying Calradia. Now, it's time to unify the continent under your own banner and etch your name into history!
