The Sarakatsani

The Sarakatsani (Greek: Σαρακατσάνοι) are an ethnic Greek population group,[4][5] who were traditionally transhumant shepherds, native to Greece, with smaller presence in neighbouring Bulgaria, southern Albania and the Republic of Macedonia. Historically centered around the Pindus mountains and other mountain ranges of continental Greece, the vast majority of the Sarakatsani have currently abandoned the transhumant way of life and have been urbanised to a significant degree.(Wiki)
