I want to know the answer to the following question:
The Ottoman dynasty was preceded by what sultanate?
All the background I'm provided with is that "Despite newer added amalgamations, the Ottoman dynasty, like their predecessors in the Sultanate of Rum and the Seljuk Empire, were thoroughly Persianised in their culture, language, habits and customs, and therefore, the empire has been described as a Persianate empire.". Is that enough to answer the question?
Answer: yes
