Mausoleum of Sultan Mahmud II

Mahmud II was the sultan of the Ottoman Empire from 1808 until his death in 1839. Often described as the "Peter the Great of Turkey", Mahmud instituted extensive administrative, military, and fiscal reforms. His disbandment of the conservative Janissary Corps removed a major obstacle to his and his successors' reforms in the Empire, creating the foundations of the subsequent Tanzimat era.
