Arthania (Arabic: ارثانية ’Arṯāniya; Russian: Арcания, romanized: Arsaniya or Артания (Artaniya); Ukrainian: Артанія, romanized: Artaniya; Belarusian: Артанія, romanized: Artania) was one of the three states of the Rus or Saqaliba (early East Slavs) with its capital in Artha (Russian: Арса, romanized: Arsa).
