The Bedrosian-Optrican war is a conflict between the Bedrosians and Optricans. The war between them began because of a difference in religious beliefs, with the Bedrosians believing in a long-departed Goa'uld, Nefertum, as their god and creator; and the Optricans believing that they had been brought through the Stargate from another world. The battle continued for several decades and appears to still be ongoing. Both nations appear to be equally advanced. (SG1: "New Ground")
