The texts of ancient Romans called it the Lake Flevo. Lake Almere is mentioned among others in a life of saints written by Bishop Anglo-Saxon Saint Boniface in 753, or a deed of gift from the town of Urk.
Its etymology may be eels, in Dutch aal or ael, so: "ael mere" = "eel lake"
Presumably, the water of Almere at that time was freshwater or slightly brackish.
A number of factors have led during the Middle Ages to the transformation of the lake to an inland sea that will be called Zuiderzee, these are:
- the rising sea levels due to global warming known as the Medieval Warm Period.
- excavation of peat by the Frisians in West Friesland, near the Vlie a river that connects Almere to the North Sea.
- the floods such as the All Saints' Flood (1170) or St. Lucia's flood 1287.
