Pisidia was an ancient region located in the southwestern part of modern-day Turkey. It was known for its rugged terrain and mountainous landscapes, which made it a challenging area for settlement. The region was inhabited by various tribes and later became part of the Roman Empire. The most notable city in Pisidia was Antioch of Pisidia, which played a significant role in early Christian history. The Apostle Paul visited this city during his missionary journeys, where he preached and established a Christian community. Pisidia's rich history reflects the cultural and political changes that occurred over centuries.
