 During Ottoman rule the town was governed by several princes (called "Şehzade") and so is also known as a "town of the princes" (Şehzadeler şehri).Many examples of Ottoman architecture were built over the next few centuries, such as the Muradiye Mosque, designed by the famous architect Mimar Sinan in 1586, and built for Murad III who was a governor of the town.By the 19th century Manisa was among the largest towns in the Aegean region of Anatolia and its population before the fire is estimated to have been between 35,000 and 50,000.
