Fódlan's recorded history begins 41 years before the founding of the Adrestian Empire, with the appearance of Saint Seiros in the Enbarr region. Seiros performed miracles that inspired the people, and the Church of Seiros was founded to venerate her.
The Adrestian Empire was founded in Imperial Year 1 by Great Emperor Wilhelm I, with Enbarr chosen as its capital due to the presence of Seiros. In Imperial Year 32, Wilhelm I launched the War of Heroes with the goal of conquering all of Fódlan for the Empire. Nemesis, the King of Liberation, united the Empire's opponents under his leadership. Seiros finally slew Nemesis at the Battle of Tailtean in Imperial Year 91, but the war did not end until 98, when Wilhelm I's successor, Lycaon I, succumbed to illness.
In Imperial Year 751, the Holy Kingdom of Faerghus seceded from the Empire after winning the War of the Eagle and Lion. The Church crowned Faerghus's first king, Loog of House Blaiddyd, and granted his nation autonomy. In 801, the region of Leicester rebelled against the Empire, and the Kingdom took the opportunity to occupy the region. In 861, the death of King Klaus I led his three sons to partition the Kingdom into three parts, with each of them ruling a part as an archduke. The death of the archduke of Leicester in 881 gave the Leicester lords the chance to form an alliance rather than accept his heir, sparking the Crescent Moon War. In 901, the war ended with the founding of the Leicester Alliance under the leadership of the influential Duke of Riegan.
The constant threat of foreign invasion from countries beyond Fódlan eventually forced the three powers to band together under the Church. As of 1180, the Church continues to exert its influence to maintain peace and harmony within the continent.
Fódlan is divided into three rival countries and the Church of Seiros, which controls a small, neutral territory in the central Oghma Mountains. While often at odds with each other, they have demonstrated a willingness to cooperate against aggression from countries outside Fódlan.
The Adrestian Empire in the south of Fódlan is monarchy ruled by an emperor. Its capital city is Enbarr, the most populated city on the continent and the seat of House Hresvelg, a dynasty that can be traced back over 1,100 years to the founding of the Empire. Recently, Emperor Ionius IX was strong-armed into ceding much of his authority to the prime minister, Duke Aegir, in the Insurrection of the Seven. With the nobility mired in corruption, Princess Edelgard has resolved to reclaim what her father lost and restore the Empire to glory.
Holy Kingdom of Faerghus
The Holy Kingdom of Faerghus in the north of Fódlan is a monarchy ruled by a king. Its capital city is Fhirdiad, an isolated yet bustling city controlled by House Blaiddyd, the royal family. Recently, the Kingdom suffered the loss of several nobles and its king, Lambert, in the Tragedy of Duscur, a misfortune that left deep scars on the populace and sparked the genocide of the people of Duscur. Crown Prince Dimitri, the only survivor of the assassination, is haunted by his experience as he prepares to assume the throne.
The Leicester Alliance in the east of Fódlan is a republic ruled by a council of nobles. Its capital city is Derdriu, an industrious port controlled by House Riegan, the noble family that leads the Leicester Alliance roundtable. Recently, amidst ongoing troubles with the neighboring kingdom of Almyra, Duke Oswald announced that his grandson Claude would succeed him. Alliance leadership had briefly been thrown into question after the death of the duke's son and previous heir Godfrey, as Godfrey had no offspring of his own and his sister, Tiana, had not been seen in years.
Fódlan is only one continent on an unnamed world. It is surrounded by a number of other continents, countries, and regions:
- Agartha - An ancient civilization.
- Albinea - A cold, barren continent to the northwest.
- Almyra - A powerful and aggressive kingdom to the east of Leicester.
- Brigid - An archipelago to west, traditionally an ally of Dagda and now a vassal of the Empire.
- Dagda - A mysterious, sprawling continent far across the western sea.
- Duscur - A small peninsula in northern Faerghus, recently subjugated by the Kingdom.
- Mach - A land that was once invaded by Dagda.
- Morfis - A city-state known for its magical expertise in the midst of a vast desert.
- Sreng - A large peninsula extending from northeastern Faerghus where warrior clans dwell.

While once the years began similar as the Gregorian Calendar, Fódlan's current calendar system uses "Imperial Year" as its era name, and the epoch or origin event of the era is the founding of the Adrestian Empire, with months coming to be known as moons, with a new year beginning with the fourth month of the calendar, Great Tree Moon, and ends with the third month, Lone Moon, corresponding with the Gregorian's April and March respectively. The events of Fire Emblem: Three Houses initially start in Great Tree Moon of Imperial Year 1180, and then resume in 1185.
The Japanese name is their spelling of Fódla, an Irish goddess and one of three sisters.
Morfis is likely named after Morpheus, the Roman god of dreams and one of the children of Somnus, the Roman god of sleep.
Brigid could be named after Brigid, an Irish goddess associated with spring, poetry, healing, fertility, and smithing, Brigid, a patron saint of Ireland, or Bridget, a saint of Sweden and founder of the Bridgettine Order.
Almyra could be named after Palmyra, an ancient city located in Syria.
Sreng is likely named after Sreng, a champion of the Fir Bolg people in Irish mythology.
- The shape of Fódlan resembles a dragon's head. This is emphasized by the names of two mountain ranges on the map: Fódlan's Fangs in the west, and Fódlan's Throat in the east, along the border with Almyra.
- According to game director Toshiyuki Kusakihara, the surface area of Fódlan is equivalent to 2/3rds of the surface area of Europe or approximately 6,786,666 sq km/2,620,346 sq miles.
