Celestia Addons

History
The Vulcans were once an extremely violent and emotional people, waging almost constant warfare on each other.
As their level of technology improved, the Vulcans' violent nature threatened the species with extinction.
Around 370 AD, the philosopher Surak led his people in a great reformation to reject their emotions in favor of a philosophy that embraced pure logic.
A group of dissenters, known as "those who march beneath the raptor's wings", did not accept Surak's teachings, and left the planet Vulcan at this time.
This group later settled on the planets Romulus and Remus and become the Romulan species, eventually forming a vast and powerful interstellar empire.

Enterprise NX-01 (pre-Federation) visited a Romulan-claimed world in 2152.
The planet had and orbital minefield with cloaked anti-ship mines.
Contact consisted of brief visual of Romulan ships and an audio-only ship-to-ship communication telling Enterprise to leave the territory of the Romulan Star Empire.

In 2155, Humans made First Contact with the Romulans via Enterprise NX-01,
Human-Romulan history was mostly a series of confrontations between United Earth.
First contact with Humans occurred in the 22nd century, which led to the Earth-Romulan War.
