Brigid is an archipelago off the western coast of Fódlan in Fire Emblem: Three Houses.


Brigid has a tropical climate and many beaches. The people of Brigid practice shamanism, which allows them to use powerful curses and commune with spirits. The spoken language of Brigid is different than the main language of Fódlan. Since 1175, Brigid has been a vassal state of the Adrestian Empire.


Following the First Mach War of Imperial Year 721, the Adrestian Empire prepared a retaliatory invasion of Dagda. To this end, the Empire invaded Brigid in 728, at the time an ally of Dagda, and forcibly subjugated it when its people refused to surrender. In 731, Brigid was used as a foothold for the attempted conquest of Dagda, but the Empire's offensive failed.

In 1175, the king of Brigid's son was slain during the Dagda and Brigid War, in which both countries jointly invaded the Imperial territories of Nuvelle and Ochs. The invasion was thwarted, though not without great cost, and Brigid was forced into vassalage to the Empire. The king of Brigid's son perished in the conflict, and his granddaughter, Petra, was subsequently sent to the Empire as a token of allegiance as a foreign exchange student at Garreg Mach Monastery.

In reality, Petra had been sent to the Empire as an unknowing hostage to ensure Brigid's compliance and prevent them from re-allying with Dagda to attack the Empire. Petra returns to Brigid and either declares independence as the Empire's vassal state or becomes a full-fledged ally of the Empire depending on which path the player takes.
