Lazistan

Lazistan (Lazona - ლაზონა in Laz, ლაზეთი - lazeti or ჭანეთი - č’aneti in Georgian) was the Ottoman administrative name for the sanjak (under vilayet of Trabzon) comprising the Laz or Lazuri-speaking population on the southeastern shore of the Black Sea. However, its boundaries did not coincide with the Laz-speaking area. It covered the land of contemporary Rize Province and the littoral of contemporary Artvin Province.
