Catan: Traders & Barbarians

1 Overview

Catan: Traders & Barbarians is an expansion for the base Catan game containing multiple separate scenario modules and new variant rules. Unlike most Catan expansions, Traders & Barbarians is a collection, you pick which scenario to play rather than combining everything at once. This makes it very modular and great for groups with varying experience levels.

2 The Scenarios

Five standalone scenarios are included:

1. The Fishermen of Catan, fishing lake added; fish traded for resources or robber removal
2. The Rivers of Catan, river hexes that provide bonus roads and settlements
3. The Caravans, add trade caravans that move between cities paying gold for passage
4. Barbarians Attack!, cooperative element: all players fight off barbarian waves while competing
5. Traders & Barbarians (Full), combines all four above modules

3 Barbarians at the Gates (Core Mechanic)

In the Barbarians Attack scenario and the full game, a barbarian token advances along a track toward Catan each time a 7 is rolled or a barbarian event card is drawn. When the barbarian token reaches Catan, an attack occurs:

• Total barbarian strength = total number of cities on the board
• Total Catan defense = total knights in play across all players
• If defense ≥ barbarian strength: attack repelled; the player(s) with most knights earn a Victory Point bonus
• If barbarians win: all players with cities that aren't defended (fewest knights) lose a city (downgraded to settlement)

This adds a cooperative pressure element to the competitive game.

4 The Caravans Mechanic

Trade caravans are placed on the board and move between cities paying "gold" (actually a new trade good) when passing through. Players who establish routes in caravan paths earn gold, which functions as a wild-card resource tradeable for anything.

Timing caravan routes to intersect your settlement locations before opponents is a spatial puzzle layered on top of the standard Catan resource game.

5 Variant Rules (Use With Any Catan Game)

Traders & Barbarians also includes several optional variant rules that can be added to the base game without any specific scenario:

• Harbors Variant: Harbor settlements are acquired via trade, not placement, changes port access strategy
• Catan Event Cards: Replace the robber die roll with an event card deck, events include resource bonuses, trade boosts, and barbarian movement in addition to the robber. This reduces pure-luck swings
• Friendly Robber: The robber cannot be moved to hexes with only 1 or 2 buildings, reduces runaway leader punishment of struggling players

6 Strategy & Tips

Barbarians Attack: Knights Are Mandatory Investment

In the Barbarians Attack scenario, players who invest zero resources in knights are taking a serious gamble. If the barbarians win and you have the fewest knights among all players, your most valuable city gets downgraded to a settlement. Losing a city costs you 1 VP and destroys the production upgrade that made the city valuable in the first place. Build at least 2 knights by the time the first barbarian attack is expected. Watch the barbarian track closely since it can advance faster than expected when 7s come up frequently early in the game.

The Caravans: Position Early, Profit Late

Caravan routes that intersect your settlement network provide passive gold income each time a caravan passes through. Settlements placed at natural caravan crossroads earn gold turn after turn without requiring player action. Identify likely caravan paths during setup and plan initial settlement placements to intercept them. Gold is a wildcard resource tradeable for anything, making it disproportionately valuable for completing whichever resource you are short on at any given moment.

Fishermen: Fish for Robber Removal

The Fishermen scenario provides fish as a tradeable commodity with several uses, but the most strategically powerful is using fish to remove the robber from your hex. Being robbed is a significant setback that blocks production for multiple turns. Being able to reliably remove the robber without relying on rolling a 7 gives you production security that other players lack throughout the game.

Start With Individual Scenarios

The full Traders & Barbarians game combines all four modules simultaneously, which is complex and can be overwhelming. Run the Fishermen and Rivers scenarios individually first. Each runs in roughly the same time as a standard Catan game and teaches its mechanics in isolation before you combine them.

7 How Traders & Barbarians Compares to Other Catan Expansions

Catan has three major expansions. Here is how Traders & Barbarians fits among them:

• Seafarers: Adds ships, multiple islands, and water exploration. Purely additive to the base game. No new victory conditions, just more map. Easiest expansion to learn and the most commonly recommended first expansion.
• Cities & Knights: Adds a full city-upgrade economy, knights with active abilities, and a detailed barbarian invasion system. Dramatically increases game complexity and length. Best for experienced Catan players.
• Traders & Barbarians: Unlike the other two, it is a scenario collection rather than one unified ruleset. You can engage with it at any complexity level by choosing simpler or more complex scenarios. The variant rules (Friendly Robber, Event Cards) are usable in any Catan game regardless of scenario, making it uniquely flexible.

Recommended order for new Catan expansion players: Seafarers first, then Traders & Barbarians starting with single scenarios, then Cities & Knights for the full complexity experience.

8 Common Mistakes

• Treating Barbarians Attack as purely cooperative. The game is still competitive. Repelling the barbarian attack rewards the player with the most knights, not every defender equally. Build knights for your own benefit, not just for the group's collective defense.
• Underestimating the Event Card variant. Replacing the robber die roll with event cards significantly reduces luck swings. Groups that love the chaos of standard Catan robber rolls may actually prefer not to use this variant. Try it both ways and see which your group prefers before making it a permanent house rule.
• Placing settlements away from caravan routes. Caravans follow a fixed path between cities. Placing a settlement near a caravan path that does not actually intersect the route earns you nothing. Trace the exact caravan route on the map before deciding your settlement placement each game.
