Barter allows an unhindered exchange of resources and facilitates building profitable trade relations with other pharaohs.
The research of Barter will bring your empire lots of benefits: on the one hand, it will help establish internal trade within your own empire, so that an unhindered exchange of resources between your own cities can take place. On the other hand, you would be able to get cheaper goods from your neighbors once the trade relations are fully established. Long distance trade expeditions to Byblos or even to Babylon for the procurement of fancy leopard furs, precious jewelry, and sharp weapons would also be possible.
