In the early 1900s, 270 Slavonic speaking Christians lived in the village.[3] After the Greek Civil War, only 10 Macedonian speaking families remained and the abandoned houses of those that fled were settled by Aromanians.[3] They were from a group of nomadic transhumant Aromanians known as the Arvanitovlachs, and the Greek government assisted them to settle in depopulated villages of the Prespa region like Kallithea during the 1950s.[4] The Aromanians originated from Giannitsa and the region of Epirus.[5]
Kallithea had 170 inhabitants in 1981.[6] In fieldwork done by anthropologist Riki Van Boeschoten in late 1993, Kallithea was populated by Aromanians and Slavophones.[6]
