During the first World War, Magarevo was occupied by the Bulgarian military who evacuated most of the Aromanian villagers and sent them into the interior of Bulgaria and Bulgarian occupation zone of Serbia. The relocation of local Aromanians was due to Bulgarian forces being concerned that pro-Greek and pro-Serbian sympathies existed among them resulting in possible cooperation with the Entente Allies. While in exile, some villagers had to fend for themselves whereas others for the Bulgarians did forced labour. Some Aromanians returning to Magarevo and neighbouring Trnovo saw the level of destruction caused by war in the villages and around 30 families from both settlements crossed the Mariovo mountains on foot into Greece for Aridaia. The Aromanians hoped that their plight and previous service during the "Macedonian Struggle" for the Greek cause would be recognised by Greece toward eventually re-establishing themselves in Aridaia.
