Tell me please if can use the preposition to after the preposition welcoming in the following sentence.
The Abbasids kept the idea of a hereditary monarchy, but they moved the capital of the empire to Baghdad, and they were much more welcoming (to) of other non-Arab muslims in positions of power.
This is from Crash Course World History. It is at 5 minute and 12 second. The use of the preposition of sounds strange to me. I have looked it up the adjective in a few dictionaries, and I have not find the examples of it used with of. Would it not be better to use the preposition to.
