The Griko people (Γκρίκο), also known as Grecanici in Calabria, are an ethnic Greek community of Southern Italy. They are found principally in regions of Calabria and Apulia (peninsula of Salento). The Griko are believed to be remnants of the once large Ancient and Medieval Greek communities of southern Italy (the ancient Magna Graecia region), although there is dispute among scholars as to whether the Griko community is directly descended from Ancient Greeks or from more recent medieval migrations during the Byzantine domination.
A long-standing debate over the origin of the Griko dialect has produced two main theories about the origins of Griko. According to the first theory, developed by Giuseppe Morosi in 1870, Griko originated from the Hellenistic Koine when in the Byzantine era [...] waves of immigrants arrived from Greece to Salento. Some decades after Morosi, G. Rohlfs, in the wake of Hatzidakis (1892), claimed instead that Griko was a local variety evolved directly from the ancient Greek.
Greek people have been living in Southern Italy for millennia, initially arriving in Southern Italy in numerous waves of migrations, from the ancient Greek colonisation of Southern Italy and Sicily in the 8th century BC through to the Byzantine Greek migrations of the 15th century caused by the Ottoman conquest. In the Middle Ages, Greek regional communities were reduced to isolated enclaves. Although most Greek inhabitants of Southern Italy have become entirely Italianized over the centuries, the Griko community has been able to preserve their original Greek identity, heritage, language and distinct culture, although exposure to mass media has progressively eroded their culture and language.
The Griko people traditionally speak Italiot Greek (the Griko or Calabrian dialects), which is a form of the Greek language. In recent years, the number of Griko who speak the Griko language has been greatly reduced; the younger Griko have rapidly shifted to Italian. Today, the Griko are Catholics.
