 After the death of the last Khwarezmaian ruler Jalal ad-Din Mingburnu, the destruction of the Nizari Ismaili state and the Abbasid Caliphate became the main Mongol objectives.In 1238, the Nizari Imam and the Abbasid caliph sent a joint diplomatic mission to the European kings Louis IX of France and Edward I of England to forge an alliance against the invading Mongols, but this was unsuccessful.The Mongols kept putting pressure on the Nizris of Quhistan and Qumis.
