This map shows the development of the Ottoman Empire over time. Its accuracy may be disputed but it is among the best Wikimedia has to offer at this time.
This animated gif is really good at what it does. With all the basic parts available, it becomes possible to expand on these maps. The Ottoman empire was divided in "eyalets" and these were divided in "sanjaks". The size and the composition of these eyalets changed over time. An animation of these changes helps understand developments in for instance the Balkan.
At this time sanjaks are added to Wikidata and, this proves to be not that straight forward. Most of them do not have an article in any language. The spelling of the same sanjak differs in places and for some eyalets a modern interpretation is sought in order to provide some "legitimacy" of later developments; in one instance even the mentioning of the composite sanjaks is deliberately missing.
The governance of the Ottoman Empire was obviously along the line of these eyalats and sanjaks. For the eyalets there were "beylerbeys" and for the sanjaks "sanjak-beys". These offices were largely non-hereditary and during one time the composition of them was for quite some time by people originating from the Balkan.
When you consider the administrative organisation of the Ottoman Empire, there is a list of all the Sultans and their Grand Viziers. For the successions of other important functionaries there is still a lot that can be done.
When you are willing to help; please. Adding labels in other languages particularly Turkish will make a real difference. Adding missing humans in Wikidata and link them into a succession of functionaries will help a lot. It enables the provision of lists and they may be used in any language. When you are able to hack maps.. That would be really important; it is how all this information may come together.
