1. Empire and the Mandate of Heaven
As the sphere of the Turyline monarchs grows, and their relative influence and power in the world does as well, the monarchical tradition of Turyline society should ultimately come into conflict with the equally-influential mercantile tradition and caste. In order to legitimize a greater control of state and cultural affairs by the monarchy, the Turyline monarchs will adopt monotheistic religion and proclaim themselves to be emperors, to rule over the Turyline eternally, by mandate of god. If there is any kind of brief civil war-type conflict, the royal family is ultimately able to suppress mercantile revolt through military superiority, and the judicious use of intermarriage of royal blood with major mercantile families. Indeed, if at all possible the interweaving of royal blood with merchant families should be used to prevent any kind of opportunity for major conflict to occur in the first place. The adoption of the Mandate of Heaven, as means of legitimizing the increased power (and continuing to increase the power of) the monarch should engender further expansionist policies. Hopefully, the Turyline emperors will be a judicious lot and will use the existing social structure of Turyline society to their advantage. At this point (prior to BT), the military is largely composed of a comparatively small standing army controlled by the monarch and the royal family, supplemented by levied poleis militias with some level of military tradition, and indentured military institutions among non-Turyline peoples in the Turyline-held Anatolian hinterlands (in the style of the ghulams). Centralization under the monarchs should give way to the full centralization of the military, as power migrates from the poleis merchants to the imperial throne, and ultimately the emperors and those who report directly to them should hold full sway over the military. What was formerly poleis levied militia should be streamlined, as the ancestral officer families that traditionally commanded Turyline armies are absorbed into the imperial command structure. The existing composite royal army will form the platform on which the new military will be based, and holding the former poleis officer families and those that reported to them to the imperial sway should not be difficult. The non-Turyline peoples who had indentured service to the throne in their blood should be Turylized as modernization reaches out into the hinterlands, to whatever extent they can be. Until such a time as they consider themselves Turyline, and are willing to report directly to the imperial throne, these non-Turyline peoples should command their own regiments and units within the new imperial military. If it can be accepted that the new Turyline emperors are a judicious lot, they should use the growing standing military to first reinforce Turyline's position as a mercantile and military power in the Mediterranean and in Asia Minor, and to ensure Turyline control over Crimea and the Black Sea.
1A. Social Aspects of Empire
I think I've painted a fairly clear picture thus far, but I'll be more specific. The intention is to centralize the existing Turyline kingdom and its client city-states not only politically but socially and culturally. As the Turyline monarchs slowly extend their control over the entirety of Turyline society, the functional autonomy of the city-states should be dissolved, as regional bodies are divided into provinces which report to the imperial throne. Chief among the things necessary to be done to ensure this transfer is successful is to tie the mercantile families to the imperial throne, as I detailed. Secondly is to slowly and gradually dissolve existing city-state governments, and reconstitute them as provincial governments fully loyal to the imperial throne. This will be accomplished by bringing the most loyal and trustworthy poleis administrators into the royal circle, and ultimately beholding these largely-familial institutions to the monarch through intermarriage, and creating the tradition of full poleis subservience to the throne. The creation of a Mandate of Heaven might tie the imperial throne to a powerful clergy, but we should prevent this from occurring. The creation of any kind of major religious infrastructure within the empire should be hampered by making the throne itself the religious epicenter; as monarchs appointed by god, the emperors are naturally god's voice on earth. Religious authority will derive from the emperor/empress and they will hold full sway, now and perpetually, over any clergy or religious infrastructure created by the full adoption of a state religion. More generally, we should accept and encourage the gradual Turylization of all the peoples within the empire, and try to gradually expunge all separate cultural identities that prove themselves detrimental to the overall unity of the imperial domain. Do this slowly, slowly, slowly, slowly, slowly. I want to avoid the various cultural conflicts that tore apart the Byzantine and Ottoman empires.
1B. Expanding the Imperial Domain
So here I'm basically going to outline what I want the borders to look like. This should be accomplished, or failed spectacularly, over a series of wars to be fought sporadically across the BT. Or perhaps more accurately, we should strive towards this, but don't destroy ourselves in the attempt. Don't fight one major, long, drawn-out conflict to annihilate our neighbors, just chip away at some of them slowly.
We should try to extend our control over Anatolia. The Vanuka are ultimately just glorified Turkish-Moroccan pirates, and naturally need to be annihilated for their assaults against good, civilized peoples like us and the Cekirdeksel. We should also try to secure the Balkans (Bosnia, Romania, Serbia, etc) and some kind of port along the Adriatic Sea. The oppressed people living under the Cekirdeksel boot in Smyrna need to join the glorious Turyline Anatolian union. We must control the Black Sea and the Levant, or at least the Black Sea. Annihilate the glorified Mongol Stekli, take their land, and drive them north into Russia and Livonia. Cooperate with the Ut, and don't try to destroy the Cekirdeksel Mediterranean empire. All we want is control over Anatolia, the Balkans and the Black Sea. The Levant would be nice, but we don't need it as much as we do Anatolia and the Balkans. In order to avoid military conquest, drive the poor and uncooperative peoples into these territories and establish a large Turyline presence in order to legitimize our claim to these territories.
2. Titles and State Stuff
If I've already stated the royal family name, consider this a retcon. The imperial throne is rightly held by the mandate of god above by the Bayesrid Emperors. Here is the official imperial title:
[Name] Emperor/Empress of the Turylines, by the Grace of God Above, Protector of the Imperial Domain
This is the desired nation name:
Turyline Empire
I might add more to this later, but at the risk of being too specific and bogging down the BT process, this is basically what I would like to have done in the best possible scenario. Eagerly anticipating seeing what the world post-BT looks like.
