Martial law is the imposition of military rule by military authorities over designated regions on an emergency basis, usually only temporary, when the civilian government or civilian authorities fail to function effectively. During the Ori plague outbreak, several nations in Africa declared martial law. (SG1: "The Fourth Horseman, Part 2")
Alternate realities[]
- In an alternate reality, President Henry Landry imposed martial law after Anubis attacked Earth in 2004. This policy was still in place when Carter arrived in 2007. (SG1: "The Road Not Taken")
