# Baghdad

- id: baghdad
- modern: Baghdad, Iraq

Founded in 762 as the Abbasid capital and, for the next two centuries, the engine room of the translation movement. Caliphs, viziers and private families paid for Greek, Syriac, Sanskrit and Persian books to be turned into Arabic at rates no city had ever sustained.
