Phocis was an ancient region in the central part of ancient Greece, which included Delphi. A modern administrative unit, also called Phocis, is named after the ancient region, although the modern region is substantially larger than the ancient one.
Geopolitically, Phocis was the country of the Phocians, who spoke their own version of Doric Greek, one of the three main dialects of ancient Greek. They were one of several small mountain states of Central Greece, whose dialects are classified as Northwest Doric.
