Haudenosaunee League is an Exploration Age Minor Civilization technology that unlocks Haudenosaunee Tomahawks and Haudenosaunee Mantlets at military buildings. After researching at a Trading Post or Tambo on a Haudenosaunee settlement, the units can be trained at Barracks, Forts, Strongholds and Agra Forts.

Effect & research conditions
The technology costs 75 Wood and 75 Coin and takes 10 seconds. Its primary effect is a production unlock rather than an immediate unit shipment or a general combat-stat bonus. Secure the Haudenosaunee settlement, establish the Trading Post or Tambo connection and use one of the listed military buildings to queue the units. Their own cost and population are separate from the research.
Research condition
Available from the Exploration Age. Research it at Trading Post or Tambo on an Haudenosaunee settlement.
When to research
Research when the Haudenosaunee units fill a role the army needs and you already have a listed production building. The low research cost can open a useful option early, but the follow-on units still need to be funded and protected. Compare their access with ordinary roster production before choosing a settlement solely for the unlock.
A cross-building production unlock
After the settlement technology is complete, Haudenosaunee Tomahawks and Mantlets can be trained at Barracks, Forts, Strongholds and Agra Forts. This lets the player reinforce from more than one structure type, depending on the civilization and map. It does not automatically add units to those queues or make all allied units trainable everywhere.
Use the settlement and army together
The 10-second research is inexpensive, but the army’s real cost comes from producing the unlocked units. Choose the technology when the force can benefit from Tomahawks or Mantlets and a suitable building can sustain production. Protect the Trading Post or Tambo that grants access so the route remains available.
