The Amarr dedicated the spoils of conquest to science, art, and philosophy. Eventually they began to spread off their planet, starting in AD 20572, when they first launched people into space. A slow expansion soon followed, especially once the Amarr discovered microbial life on the ocean world of Tamiroth. They placed a permanent colony there in AD 20725.

In AD 21134, the Amarr stumbled across the remains of a star gate. Though the ancient structure no longer functioned, they were able to reverse engineer it and construct a completely new star gate. In order to open it, they had to send a cryoship filled with materials to construct a sister gate in the nearby star system of Hedion. It reached its destination fifty-three years later. With a foreign sun lighting their progress, the awoken workers constructed the star gate and sent a signal back to Amarr. In AD 21290, the gates flared to life.
