Maishan (East Syrian Ecclesiastical Province)
The region of Maishan or Maysan (Syriac: ) in southern Iraq and Kuwait was a metropolitan province of the Church of the East between the fifth and thirteenth centuries. The metropolitans of Maishan sat at Prath d'Maishan (Syriac: ), and for most of its history the province had three suffragan dioceses, at Karka d'Maishan (Syriac: ), Rima (Syriac: ) and Nahargur (Syriac: ). The last metropolitan of Maishan, the noted East Syrian author Shlemun (Solomon) of Basra, is attested in 1222, and it is not clear when the province ceased to exist.
