Shah Rukh was a great patron of the arts and sciences, which flourished under his rule. He spent his reign focusing on the stability of his lands, as well as maintaining political and economic relations with neighbouring kingdoms. In the view of historians Thomas W. Lentz and Glenn D. Lowry, "unlike his father, Shahrukh ruled the Timurid empire, not as a Turco-Mongol warlord-conqueror, but as an Islamic sultan. In dynastic chronicles he is exalted as a man of great piety, diplomacy, and modesty – a model Islamic ruler who repaired much of the physical and psychological damage caused by his father."
