AL-QADISIYYAH (HISTORICAL CITY)

Al-Qadisiyyah is a historical city in southern Mesopotamia, southwest of al-Hillah and al-Kufah in Iraq. It is most famous as the site of the Battle of al-Qadisiyyah in c. 636, which saw a force of Arab-Muslim invaders defeat a larger army sent by the Sasanian Empire.

Commercial importance :

Prior to the Arab conquest, al-Qadisiyyah was but a small village on the western side of the Euphrates River, near an old castle at `Udhayb, and was possibly part of the Wall of the Arabs (Iranica, al-Qadisiyyah). [clarification needed] However, during the centuries that followed, al-Qadisiyyah grew in size and importance and was a noted stop along very important highways of commerce that led to Baghdad and Makkah (see Alavi, 100).

Another historical Qadisiyyah :

Another Qadisiyyah existed on the Tigris River, off the road between Baghdad and Samarra', not very far from the Euphrates city. Both cities are recorded in the geographies of Ibn Khordadbeh (see Barthold, 202).
