Why did the Ottoman sultan refuse to extradite Lajos Kossuth to Austria and Russia?

The Ottoman sultan refused to extradite Lajos Kossuth to Austria and Russia primarily due to diplomatic pressure exerted by Western powers.1

Following the collapse of the Hungarian Revolution of 1848–1849, Kossuth sought refuge in Turkey. Both the Austrian and Russian empires demanded his surrender; however, the intervention of other international powers encouraged the sultan to deny these requests. As a result of this diplomatic protection, Kossuth was not extradited but was instead interned for two years in Kütahya, Anatolia, before eventually traveling to England and the United States.21
