According to tradition, the village was founded by shepherds who found an icon in a bush. Its inhabitants lived in the village in the summer and in the winter they moved to villages at lower elevations, such as Agia Triada, Ano Gatzea and Kato Gatzea. The village revolted during the Greek War of Independence of 1821, but the revolt was suppressed by the Ottoman Pasha Dramali and the village was burnt. Agios Georgios joined the rest of Greece in 1881. The village became a part of the municipality of Nileia (named after the ancient city Nelia, located close to modern Volos), which was dissolved in 1914. Agios Georgios Nileias was an independent community from 1914 until 1998, when it became part of the municipality Milies.
