Pertevniyal Sultan, was a consort of the Ottoman Sultan Mahmud II, and Valide sultan of Sultan Abdulaziz.

Mahmud II was the sultan of the Ottoman Empire from 1808 until his death in 1839. Often described as "Peter the Great of Turkey", Mahmud instituted extensive administrative, military, and fiscal reforms which culminated in the Decree of Tanzimat ("reorganization") that was carried out by his successors. His disbandment of the conservative Janissary corps removed a major obstacle to his and his successors' reforms in the Empire. Mahmud's reign was also marked by further Ottoman military defeat and loss of territory as a result of nationalist uprisings and European intervention.
