 There are two small Griko-speaking communities known as the Griko people who live in the Italian regions of Calabria, the southern tip of the Italian peninsula, and in Apulia, its south-easternmost corner.These varieties too are believed to have developed on the basis of an originally Doric ancient dialect, and have preserved some elements of it, though to a lesser extent than Tsakonian.They subsequently adopted influences from ancient Koiné, but became isolated from the rest of the Greek-speaking world after the decline of Byzantine rule in Italy during the Middle Ages.
