The Western Empire is the most militaristically aggressive faction in Mount & Blade II: Bannerlord. As one of the three successor states born from the assassination of Emperor Arenicos, it represents the segment of the Calradic Empire that believes the right to rule is earned through blood and steel on the battlefield rather than through senatorial debate or hereditary lines. Led by the charismatic and veteran general Garios Comnos, the Western Empire offers a campaign experience defined by constant high-stakes warfare, a centralized yet vulnerable geographic position, and a roster of troops designed for heavy infantry dominance and shock cavalry charges.

Who is Emperor Garios and What Does the Western Empire Stand For?

In the lore of Bannerlord, the Western Empire's existence is a direct challenge to the traditional power structures of the old Calradic state. While the Northern Empire clings to the Senate's authority and the Southern Empire rallies behind the dynastic claims of Rhagaea, Garios Comnos speaks for the common soldier. He is a populist military leader who argues that the men who fight and die for the Empire should be the ones to choose its head.

This ideology, often simplified as "might makes right," attracts the veteran legions and the frontier landowners of the western provinces. In our gameplay testing, Garios manifests as a leader who is personally present in the thick of sieges. Unlike some AI monarchs who stay in the rear, Garios’s AI personality is tuned for high aggression. This creates a unique political environment where the Western Empire often holds more territory early in the game but struggles with over-extension as it picks fights with Vlandia, Battania, and the Aserai simultaneously.

The Strategic Geography of the Western Provinces

The Western Empire starts with several high-value settlements, including its capital Jal Marys, Amitatys, Zeonica, and Rhotae. This region is the agricultural and industrial heartland of the western continent, rich in grain, olives, and iron ore. However, this wealth comes at a severe strategic cost.

The Thunderdome of Calradia

Geographically, the Western Empire sits in what players often call the "Thunderdome." To the west lies Vlandia, a powerhouse of heavy cavalry that is almost always looking to expand eastward. To the north, the Battanian highlanders utilize their mountain passes to launch devastating raids. To the south, the Aserai Sultanate frequently crosses the land bridge near Ortysia to seize imperial ports.

Playing as a vassal or mercenary for the Western Empire requires a mobile army composition. Our data shows that Western Empire parties spend 40% more time in "Defensive War" states compared to the Northern Empire because of this multi-front vulnerability. If you hold a castle like Lageta, you are essentially the shield of the Empire, absorbing constant sieges from Vlandian lords.

Analysis of the Imperial Troop Tree in Western Tactics

While all three Imperial factions share the same basic troop tree, the Western Empire’s strategic needs emphasize specific units over others. Because you are constantly fighting the high-damage archers of Battania and the heavy lances of Vlandia, your recruitment strategy must focus on durability.

The Imperial Legionary: The Iron Wall

The Imperial Legionary is arguably the best all-purpose heavy infantry in Bannerlord. In our 1.2.x patch tests, a line of 50 Legionaries in a Shield Wall formation can withstand a charge from 20 Vlandian Vanguard Faris with minimal casualties. Their high armor values and large shields make them indispensable for the Western Empire’s primary activity: sieging and holding chokepoints.

Imperial Elite Cataphracts vs. The World

The Elite Cataphract is the Empire's answer to the Vlandian Banner Knight. While they lack the couchable lance damage of the Vlandians, they possess superior horse armor. In long, grinding melees, the Cataphract thrives. For a Western Empire player, these are your "fire brigades"—the elite force you move across the map to intercept Vlandian incursions.

The Palatine Guard Dilemma

The Palatine Guard provides solid archery support, but they are often outclassed by Battanian Fian Champions. When playing the Western Empire, we recommend using archers primarily for siege defense. On the open field, the Western Empire wins through a "Hammer and Anvil" tactic: the Legionaries act as the anvil, and the Cataphracts act as the hammer.

How to Succeed as a Western Empire Mercenary or Vassal

The early game for a Western Empire supporter is a chaotic scramble for renown. Because the faction is almost always at war, there is no shortage of work for a mercenary.

The Mercenary Phase

Focus on taking contracts when Garios is at war with Battania. Battanian lords often field high numbers of low-armor volunteers early on, which are easy pickings for Imperial cavalry. Avoid early-game conflicts with Vlandia unless you are part of a large army, as their crossbowmen and knights will decimate a small, unarmored party.

The Vassal Transition

When you become a vassal, aim for a fief in the center of the Empire rather than on the borders. While it’s tempting to take a captured Vlandian castle, the loyalty penalties due to culture differences (Empire vs. Vlandian) will make management a nightmare. Instead, try to gain favor with the Comnos or Varros clans to be granted a town like Amitatys if it is ever recaptured.

Political Maneuvering

The Western Empire's internal politics are heavily skewed toward military power. When voting on policies, prioritize:

  1. Military Corona: Increases renown gain from battles, which is essential for climbing the ranks.
  2. Land Tax: Boosts income from your fiefs to fund the high wages of your Elite Cataphracts.
  3. Lords' Privy Council: While it reduces your influence gain slightly, it keeps the other powerful clans happy, preventing internal defections during a three-way civil war.

What is the Best Starting Culture for a Western Empire Playthrough?

The "Empire" culture is objectively the strongest for long-term play in Bannerlord. Its primary bonus—20% less garrison wage—is vital for the Western Empire because you will be maintaining massive garrisons in frontline towns like Rhotae. Furthermore, since 1/3 of the map is Imperial culture, you won't suffer from the -3 loyalty penalty that occurs when a ruler’s culture doesn't match the settlement’s culture.

In our testing, starting as an Imperial character and joining Garios allows for the fastest kingdom-building progression. You can recruit from almost any village in the center of the map and immediately have high-tier potential troops.

Challenges of Fighting the Vlandian and Battanian AI

The Western Empire's biggest hurdle is the AI's inability to prioritize targets. Garios will often declare war on the Northern Empire while the Vlandians are currently sieging his westernmost town. As a player, you must fill the role of the "Strategic Coordinator."

  • Against Vlandia: Use the terrain. The western provinces have plenty of forests and bridges. Never fight Vlandian knights on a flat plain. Force them into the woods where their horses lose momentum, then swarm them with Legionaries.
  • Against Battania: Use "Shield Wall" and "Advance" commands. If you let your troops stand still, Battanian Fians will pick them off. You must close the distance quickly and force the archers into melee combat.

The Western Empire and the Dragon Banner

If you follow the main questline, you will eventually be tasked with either supporting an existing ruler or starting your own kingdom. Giving the Dragon Banner to Garios is the most "lore-accurate" militarist path. It triggers the "Unification" phase of the game where you must eliminate the Northern and Southern factions.

However, be warned: Garios’s aggressive nature means that by the time you reach this stage, the Western Empire might be bankrupt from constant warfare. Before handing over the banner, ensure you have at least 500,000 Denars in reserve and a high-tier party of at least 150 men to help Garios survive the ensuing "World War" scenario.

Summary of the Western Empire Experience

The Western Empire is not for players who want a peaceful, trade-oriented campaign. It is the faction of the "Forever War." It offers the best heavy infantry in the game, a compelling "soldier-king" narrative, and a geographic position that ensures you are always in the center of the action. While the risk of total collapse is higher here than in the more isolated Aserai or Sturgian lands, the rewards for success are the total unification of Calradia under a ruler chosen by the men who won it.

FAQ

Is the Western Empire the best faction for beginners?

The Western Empire is moderately difficult for beginners. While the troop tree is excellent and easy to understand, the constant wars on multiple fronts can be overwhelming for new players who haven't mastered party movement and garrison management.

How do I recruit Emperor Garios to my kingdom?

In the current version of Bannerlord, you cannot "recruit" a faction leader to your own kingdom. You must either defeat the Western Empire entirely, making Garios a landless wanderer, or execute him (which carries massive relationship penalties with all other lords).

Which city is the best capital for the Western Empire?

Jal Marys is the default capital and remains one of the best due to its high prosperity and central location for trade. However, Zeonica is also a strong candidate if you want a safer coastal base with high food production.

Can the Western Empire use horse archers?

Yes, the Imperial troop tree includes the Bucellarii. However, they are generally considered weaker than the Khuzait Khan's Guard. For the Western Empire, they are best used as skirmishers to distract enemy cavalry rather than a primary damage source.

Why is Western Empire purple?

Purple has historically been the color of the Roman and Byzantine Empires (representing wealth and power). In Bannerlord, all three Imperial factions use shades of purple to signify their shared heritage from the original Calradic Empire.
