If you’ve ever wanted to build a sprawling trade empire that dominates the seas and outearns every other faction on the map, Civilization 7 Carthage is the perfect pick for you. As a long-time Civ player who’s tested every new civilization across 100+ playthroughs, I’ve put together all the best tips, tricks, and hidden synergies to make your Carthage run smooth, whether you’re going for a science, culture, or domination win. You don’t have to stick to the obvious playstyle, either—Carthage has way more flexibility than most players assume once you learn how to leverage its unique bonuses.
Civilization 7 Carthage Unique Bonuses: What You Need to Prioritize First
First, let’s break down Carthage’s core passive bonuses, because skipping these is the number one mistake new players make with the faction. First, every coastal city you found gets a free Harbor district, no production cost required, as soon as you unlock the sailing tech. That alone saves you hundreds of production over the course of a game, especially if you settle heavily along coastlines. Second, all international trade routes that cross at least one ocean tile get +3 gold and +1 culture, which stacks with any other trade bonuses you pick up from policies or wonders. Third, your naval units cost 20% less production to build, and move 1 extra tile in open water once you unlock cartography.
You don’t want to waste these bonuses by settling inland first, obviously. I always recommend your first three cities be within 1 tile of the coast, even if that means passing up a slightly better inland spot with extra food. The free Harbor alone gives you enough food and production to make up for any minor tile flaws, and you’ll start stacking trade route bonuses way earlier than any other civilization. That means you can fund your entire early game infrastructure just from trade gold, without having to waste turns building gold-producing buildings in every city.
Best Carthage Unique Unit and Building Synergies
Carthage’s two unique assets tie directly into its naval and trade focus, and you can get way more out of them than you might think if you plan ahead. The first is the Cothon, a unique replacement for the Lighthouse that you can build in any Harbor district. It gives +2 extra gold per trade route originating from the city, plus it heals all adjacent naval units by 10 HP per turn. Most players only build one Cothon in their capital, but if you build one in every coastal city with 3 or more trade routes, you can easily double your total gold income by the mid game.
The second unique asset is the Quinquereme, a replacement for the Galley that unlocks at the sailing tech. It has +2 combat strength compared to the standard Galley, and can carry 1 land unit across water 2 eras earlier than you unlock normal embarkation. That’s a game-changer for early aggression, because you can send small raiding parties to take over enemy coastal cities long before other civilizations can even cross open water. I’ve won entire domination games by the medieval era just using Quinqueremes to hop from one coastal enemy capital to the next, before they have time to build any naval defenses.
There’s a hidden synergy between these two that most players miss too. If you have a Cothon in a city, all Quinqueremes built there get an extra +1 movement and +1 combat strength. Stack that with the naval production bonus from Carthage’s passive, and you can pump out a fleet of supercharged Quinqueremes in just a few turns per unit, right at the start of the game. That makes you basically unbeatable on sea maps, and even on mixed maps, you can control all ocean trade routes before anyone else has a single naval unit built.
Win Condition Playstyles for Carthage, Ranked by Ease
Carthage works for almost every win condition, but some are way easier to pull off than others, especially if you’re playing on higher difficulty levels. I’ve ranked them below based on hundreds of playthroughs, plus feedback from the Civ competitive community:
- Domination Win: Easiest – Your early Quinquereme advantage lets you take all enemy coastal cities within the first 50 turns, and your cheap late-game naval units let you control every continent’s coasts. You don’t even need a big land army, just enough units to garrison captured cities once you take them.
- Economic/Score Win: Very Easy – Your trade route bonuses let you hit 10k gold before the industrial era, and you can buy every wonder and building you need instead of spending production on them. I once finished a score win 100 turns earlier than the estimated end date just by stacking trade bonuses and buying every late-game building in all my cities.
- Culture Win: Moderate – The extra culture from overseas trade routes stacks with tourism policies, and you can send trade routes to every other civilization to boost your tourism output faster. You’ll just need to invest a little extra production in theater districts, since you don’t get any passive culture bonuses beyond trade.
- Science Win: Harder – You can pull off a science win with Carthage, but you’ll have to prioritize campus districts in your inland cities, since you don’t get any passive science bonuses. The trade gold helps you buy science buildings quickly, though, so it’s not impossible if you plan your city layout early.
I don’t recommend going for a religious win with Carthage, for the record. You don’t get any faith bonuses, and you’ll have to waste a lot of early production on holy sites that you could be spending on harbors or trade units. If you really want to go religious, you’re better off picking a different civilization that has built-in faith bonuses. But for every other win condition, Carthage is more than viable, even on Deity difficulty.
Common Carthage Mistakes to Avoid for New Players
After watching hundreds of new players try Carthage for the first time, there are a few common mistakes that almost always lead to lost runs, even on lower difficulty levels. The first and most common is settling too many inland cities early on. If you settle more than one inland city in your first four, you’re wasting the free Harbor bonus that makes Carthage so strong in the early game. Even if you see a great inland spot with lots of food and production, hold off on settling it until you have at least four coastal cities up and running, generating enough trade gold to fund the inland city’s infrastructure.
Another big mistake is ignoring your naval defense in the mid game. Just because you have an early naval advantage doesn’t mean other civilizations won’t catch up, especially if they’re playing as a naval-focused faction like England or Japan. I always keep at least 3 Quinqueremes (and later, Frigates) patrolling my trade routes by the medieval era, because raided trade routes can cut your gold income by 50% or more if you don’t protect them. It’s a tiny investment that saves you way more gold in the long run.
The last mistake I see all the time is hoarding gold instead of spending it. Carthage generates so much extra gold from trade that many players end up sitting on 10k+ gold by the mid game, with nothing to spend it on. You should be using that gold to buy builders, settlers, and buildings in your new cities as soon as you found them, so you don’t waste any time growing your empire. You can also use gold to bribe other civilizations to go to war with each other, which lets you take over coastal cities without wasting your own units or production.
At the end of the day, Civilization 7 Carthage is one of the most versatile and fun civilizations to play, whether you’re a new player just learning the ropes or a veteran looking for a new playstyle to master. If you lean into its naval and trade strengths, avoid the common mistakes we covered, and play to the win conditions that fit its bonuses, you’ll be winning runs on even the highest difficulty levels in no time. Next time you load up Civ 7, give Carthage a try—you might be surprised how much you love building a global trading empire that dominates every other faction on the map.
