Overview
This guide contains information on the achievements in Thrones of Britannia. Disclaimer: No mods were used in the making of this guide.Note 1: A work in Progress The guide is largely finished. All that is left are a handful of general achievements, and the faction-specific achievements for several factions. For now the completed sections are marked as complete, although I will remove those markers once the entire guide is finished.I will only include icons for the achievements I have collected myself. Others will be shown with a Steam locked icon.Note 2: On the naming of things.The factions are ‘Viking Sea Kings’ and ‘Great Viking Army’. To prevent confusion this guide refers to them as ‘Sea Kings’ and ‘Great Army’.Note 3: Give a ratingI would like to ask you to rate the guide if you found it helpful (or if you did not find it helpful). I dislike asking this of people, but as most of the older guides have received enough ratings over time, it would increase the visibility of this guide if it had some ratings as well. Note 4: AcknowledgementsThe information collected in this guide was gathered by:- playing the game (duh!), – browsing the internet & steam forum – a similar guide by Simon07That one will likely serve you better, if you are simply looking for an organised listing of the achievements and their requirements. My guide, on the other hand, aims to be in-depth and to provide useful tips for obtaining the less obvious / more difficult achievements.
General achievements:
Defeat someone who already has this achievement in any multiplayer battle.
This is the only multiplayer achievement (thank “the nailed god” for that!). This will probably be the last achievement I get, as I don’t play multiplayer.
– Diplomacy [complete]
Playing as any faction, marry a rival king’s daughter and then destroy his faction through conquest.
Playing as any faction, destroy another faction after they break your alliance.
Playing as any faction, complete the main campaign without negotiating peace with any other faction.
Playing as any faction, complete the main campaign by instantly declaring war on newly-encountered factions and without negotiating peace at any point.
Another option is to attempt to sign a military alliance with a trustworthy faction. Then declare war to all other factions (which they will join) before breaking the alliance. This can be very helpful in the early stages (when all factions will send armies your way), as this gives them another enemy.
I’d started the same campaign before, and I had sold as many declarations of friendship as I could. I ended up with over 8000 gold (starting money was 6000, no idea whether that’s due to easy difficulty or a Sudreyar thing). However, I soon got overwhelmed when 5 or 6 big armies landed near one of my towns (and more kept coming), and although I could stop them from taking my cityI couldn’t finish them off. When they all started raiding my economy quickly collapsed and I decided to start over with the military alliance method.
Playing as any faction, win the game having declared war on every faction in the turn you encountered them, as well as never negotiating a peace treaty.
Playing as any faction, complete the main campaign by achieving a Short victory whilst maintaining control over all your vassal kingdoms.
Playing as any faction, complete the main campaign having turned all your enemies into vassal kingdoms.
– your enemy is destroyed by another AI faction. So try to engage in conflicts with small factions so you can quickly subjugate them into submission, before anyone else can destroy them.
– you cancel ‘vassal status’ for any of the defeated factions. Keep vassals alive and under your command.
– Mierce –> It can be difficult to subjugate Mierce if they take any Welsh territory. So it is best to either let the other Welsh factions retake those areas before you subjugate them. If this is no longer possible, you can either attempt to subjugate them, or revert to an earlier save.
– West Seaxe –> There are two vassals of West Seaxe in Wales. These will declare independence at some point. However, the moment they do that seems to be random. Around turn 50 in one of my legendary attempts I controlled all of Wales except for one of those faction’s areas. By the time I got to turn 135 one of them still hadn’t declared independence.
Playing as any faction, complete the main campaign without running into negative food and with no rebellions.
Playing as any faction, complete the main campaign without any rebellions or usurpers challenging your rule.
– Characters
Playing as any faction, ensure that every characters loyalty remains above 1 for the entire campaign.
Playing as any faction, complete the main campaign, with the difference between the influence of the faction leader and the current lowest influence of any other character being never greater than 4 points.
Playing as any faction, gain a Legendary attacker.
Playing as any faction, gain a Legendary defender.
I would recommend going for this achievement on hard difficulty at least, rather than on lower difficulties. In order to get these achievements you need to get the trait for “Winning a Heroic Attack/Defense” to level 3.
Enemy armies are less aggressive on easier difficulties and my tactic for both “Legendary Defender” and “Legendary Attacker” is build around being attacked by strong armies.
To determine whether a victory is seen as Heroic or Decisive, the game seems to compare each army’s size. However, the ‘army size’ value seems to be based on the number of men, as well as the number of units on each side.
This means you can easily achieve Heroic victories (either attacking and defending) by having an army that only consists of the general’s unit. You can garrison this army inside a city to defend the town against large armies. Once you’ve beaten the attackers, you can use the general unit to take out the surviving few stacks.
Beating these armies will count as Heroic victories as long as they have multiple units; even if you have more men! (as can be seen on this screenshot) [link]
Playing as Mierce, I decided to send a strong army to Ireland ASAP (somewhere between turn 10 & 20) to capture Dún Pátraic. This allowed me to unlock the Research part of the tech tree very early, but more importantly (for these achievements), it created a ‘bait city’ for the AI. Since the AI usually attacks the town closest to their own territory, the AI regularly sent large stack armies to the town, yet ignored my remaining territory.
Once I had captured the city from Ulaid I made peace with them to strengthen the town and let the garrison replenish. By the time this was accomplished Ulaid had been defeated, so I declared war on Aileach (and so their vassal Airgialla) and Sudreyar (and their military ally Orkneyar).
I found Dún Pátraic to be an excellent settlement for this purpose, as the town has only 1 gate. This means the entire army (and any reinforcing land armies) are forced through a single gate. They might also deploy several towers, yet with 3 or 4 archer units you should be able to burn at least 1 or 2 of them before they reach the wall (and it doesn’t rain).
It does have large stretches of beach area where amphibious assaults can land, yet I barely had any amphibious assaults at all. Instead most armies came over land from the north.
Playing as any faction, gain a Legendary general.
Playing as any faction, gain a Legendary governor.
- Authoritative (level 3) – gained from having 10 influence
- Bountiful (level 3) – gained from not having food shortages
- Peacekeeper (level 3) – gained from +10 happiness
In the end I ‘trained’ my governors to max level quickly by making them generals. Towards the end of your campaign, generals will have several buffs that give them XP each turn. They also get XP for taking towns or defeating enemy armies. While leveling this general up I would pick traits that would prove useful as a governor, rather than a general (e.g. scribe, bard, forager, etc.).
Once a general was level 9 or 10 I switched them to governor. I would assign him to a province with at least +10 happiness (without a governor) and 100+ food. In most cases these characters would have max influence already, but in case they didn’t I would give them some estates to increase that as well.
I tried this approach with a substantial number of generals, and in the end my king was the one to have max level and all 3 traits. It took a few turns for him to obtain the legendary governor trait.
Playing as any faction, gain a Legendary military leader.
- Forge
- Arena
- Garrison
Once the buildings have been built (do not need to be max level), the governor will obtain the trait eventually.
– Territory [complete]
Playing as any faction, complete the main campaign whilst maintaining ownership of your starting regions.
There are a number of achievements that require you to capture specific regions. Most of these achievements require a certain top-level building, so you either need to upgrade them yourself, or let the enemy to fully upgrade them for you.
Playing as any faction, conquer all regions on the campaign map in less than 200 turns.
1) Strong military units.
2) no sea-battle debuff.
– This provides a huge bonus when fighting sea battles (or amphibious sieges), against everyone except other sea-king factions.
3) +15% campaign movement speed.
– This faction-buff allows you to move armies around much quicker.
4) starting location.
– You start with a monastery building in your city, which means you can quickly unlock the research branch in the tech tree.
– Also, by starting all the way in the north you can sweep your armies south, only establishing the occasional guard army to defend against viking invasions (which are relatively rare on easy difficulty).
– Finally, by starting way up north you have more distance between your neighbours at the start. This means you can more easily defend against enemies. By the time you reach the more densly populated southern areas you’ll have strong armies to quickly take many settlements.
Playing as any faction, own the Rock of Caisil, Mountain Hall, and Offa’s Hall buildings on the campaign map.
Tip: The buildings are the main hall of following towns. It is not necessary to fully upgrade them:
The towns are listed from left to right (West to East) on the campaign map.
[The campaign map can be found at the end of this guide]
Playing as any faction, conquer all the cities on Nennius’ list.
Playing as any faction, own all of the Saints’ buildings on the campaign map.
Tip: The buildings are located in the following towns:
Major settlements:
Minor settlements:
The towns are listed from left to right (West to East) on the campaign map.
[The campaign map can be found at the end of this guide]
Playing as any faction, own all Longphort and Viking Port buildings on the campaign map.
Tip: To obtain this achievement you must fully upgrade the town hall (level 5) and the port (level 3) in the following towns:
The towns are listed from left to right (West to East) on the campaign map.
[The campaign map can be found at the end of this guide]
– Battle [complete]
There are a number of achievements that require you to fight every battle during a given campaign. This means no auto-resolve! These achievements are not faction-specific, so you can pick whomever you like for these ones.
Playing as any faction, play and win a battle whilst heavily outnumbered.
– Catapults:
I put the 2 catapult regiments from my army at the coast together with a couple of strong infantry units and some javelin throwers. The catapults took out 90% of the fleet before they even managed to get on land. My infantry units quickly overwhelmed those that did.
– Archers:
On the other side of town I put all my archer regiments (5 in my case) on the wall to shoot fire arrows at their siege towers. This way I managed to set all (three) of their siege towers ablaze before they reached my walls. (This part will not work if the enemy attacks during the rain). if they attack during the rain, you’ll have to either also defend against the siege towers, or see if you can bottleneck them anywhere else in the settlement.
– Gate:
This only left the battering ram, I had already positioned my strongest regiment in shieldwall just behind the gate, with all my levy spear-regiments behind it. This holds the enemy at the gates, and lets the towers & boiling oil do the rest. Note that while 1 or 2 strong regiments can already pretty much hold back an entire army at the gate, you need to have enough troops at the gate to prevent the enemy from disabling the oil and towers.
-Cavalry:
During the deployment phase, I had positioned my cavalry (2 regiments, governor, and general) at a different gate. Once the battle was on its way and the main gate was breached I rode out of the second gate and positioned my cavalry outside the besieged gate. This step was not needed to win the battle, but I used them to run down fleeing soldiers. (Be careful you don’t run your cavalry into back of the soldiers attacking the gate. The boiling oil is highly effective against cavalry).

The title of this next achievement says it all! Those who wish to get it, be warned!
Playing as any faction, complete the main campaign, achieving an Ultimate victory on Legendary difficulty by fighting and winning every battle.
– Victory [complete]
There are 3 victory achievements per difficulty level; a short, long, and ultimate victory.
Adapting your strategy to suit the AI’s weakness is still strategy, applying real-world historical strategies against an AI that plays by different rules is just dumb (for instance raiding towns, even though the AI has a big food bonus over the player).

Faction achievements:
– Culture [complete]
The English Kingdoms don’t have their own cultural achievement (anymore).
Playing as any of the Gaelic kingdoms, annex all surviving Gaelic factions.
I think it only matters that you, as a player, don’t vanquish any Irish factions, but if the computer does so it is no problem. This theory is based on a forum post from someone claiming they conquered multiple factions and only annexed the final one. Apparently this did not trigger the achievement for them.
As a final note, Scotland was completely taken over by Sudreyar and Orkney by the time I annexed the last Irish faction (so no more Scottish Gaels). This could also be one of the reasons why it did trigger for me and not for other people.
Legitimacy as Mide:
I moved this section to a separate guide:
Playing as the Great Viking Army, complete the main campaign while keeping both the English and the Army happy at all times.
– leaning towards the English side of the two middle squares, as it is easier to declare war on a faction when it jumps into the green, than it is to make peace.
– try to declare war on small factions and subjegate them ASAP to return the meter to its original position.
Playing as the Viking Sea Kings, reach the maximum possible tribute level.
Playing as any of the Welsh kingdoms, complete the main campaign while keeping heroism over 20 and never falling beneath 20.
– play a complete campaign for either of the Welsh factions, or
– select ‘easy’ and quickly obtain this achievement through short victory.
I went for short victory with Gwined on easy difficulty. It took me 54 turns to conquer all of Wales and thereby achieve a short kingdom victory. The achievement popped at the beginning of turn 55.
right click the game in your library > select properties > go to the “betas” tab > select “allegiance_patch – allegiance_patch > hit “close”
The game will need to ‘update’ before you can play; which might take a while.
Achievements per faction:
The following sections will list the faction specific achievements for each faction. Each section is broken down into 4 category: general achievements, short victory, long victory, ultimate victory.
Each faction has a ‘complete campaign’ achievement, and a ‘conquer all of’ achievement. Some factions have an extra achievement as well.
This table lists the area each faction has to conquer.
Each faction has an achievement for each victory type. The different types are:
(the exact number varies between factions)
(which buildings and how many varies per faction)
provinces. Some factions have a secondary requirement for this victory (for instance Mide and Northymbre).
(the exact number varies between factions)
(which buildings and how many varies per faction)
provinces. Some factions have a secondary requirement for this victory (for instance Mide).
throughout the campaign (so also those single army fleets that spawn earlier). A number of turns
after achieving a Long victory, several large fleets spawn at once. It seems the number of fleets
depends on the difficulty of the campaign (3 fleets for legendary, 2 for very hard, and 1 for hard).
– Garrison (increases town garrison & reduces travel distance for enemy armies)
– Forge (weapon & armour upgrade for all garrisoned units *)
– Arena (army and garrison units in the province gain extra experience & they replenish quicker)
– Granary (food producing building ensures you have continue to have a certain amount of food even if the smaller villages are taken / raided)
* Since the Forge only provides the upgrades for garrison units added after the forge was built, it is advisable to build the forge before the garrison, and before the town is fully upgraded.

annex factions as Mide. I have also published a separate guide on how Legitimacy
works for Mide.
Playing as Mide, complete the main campaign by achieving a Long Conquest victory.
However, if you are also trying to annex all Gaelic factions during this playthrough,
it is best to wait with your conquest outside of Ireland until you have obtained this achievement. Every settlement the AI takes from you is -1 legitimacy, and only
settlements in Ireland provide +1 legitimacy when conquered. This means if you have
settlements outside of Ireland, and they get taken by the AI, you’re wasting legitimacy. (more information on legitimacy is in the “Culture achievements” section).
Playing as Mide, complete the main campaign by achieving a Long Fame victory.

Tip: If you want to obtain all Strat Clut achievements in 1 run, make sure you do [Western Alliance] before this one.
