The Thessalian league was a loose confederation of Thessalian city states. After the Macedonian War of 200-197 BC, all of Greece was declared free by the victor, Roman general Quinctius Flamininus. Thereafter, he reorganized the Thessalian league, creating a council and annually changing officers. The seat of the league was in the largest Thessalian city, Larisa, and the Thessalian League continued to exist even after Thessaly became part of the new Roman province of Macedonia in 146 BC. Athena was the patron deity of Thessaly, her sanctuary was said to be located between Larisa and Pherae.
