BaradÃÂn (or al-BaradÃÂn) was a town in Lower Mesopotamia under the Abbasids. The name is said to derive from Persian barda-dÃÂn ("place of prisoners"), perhaps a reference to the settlement of Jewish exiles in Babylonia.
According to the Arab geographers, it was located east of the Tigris river about due north of BaghdÃÂd. It lay on the road to SÃÂmarràand beside the KhÃÂliá¹£ canal, a branch of the NahrawÃÂn. Between it and BaghdÃÂd there were two postal stations.
For a short time, the Caliph al-Maná¹£à «r made his capital at BaradÃÂn before founding the city of BaghdÃÂd as a new capital in 762. Eventually, a gate, a street, a bridge and a cemetery in eastern BaghdÃÂd were named after BaradÃÂn. By about 1300, when the Maraṣëd al-iá¹Âá¹ÂilÃÂÿ, an abridgement of the encyclopedia of YÃÂá¸³à «t, was compiled, BaradÃÂn was in ruins and completely uninhabited. It probably corresponds to the mound today known as BadrÃÂn.
