Ofis or Ofeos is a region situated approximately 60km east of Trabzon and 20 km west of Rize. Its name is derived from a river that runs through its western border called the Ofsou river or Kalopotamos. A large proportion of the Greeks in the region were Islamized in the 17th century however they retained the Pontic dialect and customs. The region also contained a number of Christian Greeks. In total prior to 1914 there were approximately 1,700 Greeks living in the Ofis region (ethnic Greeks and Islamized Greeks combined).
