I've read dozens of posts about the lack of a unique government type for the Byzantine Empire and was wondering if any of you Byzentinophiles had any thoughts on how to make such a system in-game. The most glaring issue seems to be title management because a viceroy system ala CK2 would be way too micro heavy, so how to solve this issue in a way that works in-game? Any thoughts?
Byzantium was weird, administratively it was always a bureaucratic state, but militarily it evolved and adapted over the course of the games time frame, with 876 being in the hayday of the theme system, the theme system militarily was a set of settled, semi standing armies, each soldier was given a temporary plot of state owned land to manage but was primarily a soldier to the point that the land grants were used more to allow the solders to raise families then as pay. Any soldier in a theme passed there obligations on to there sons who would take the fathers place as per the contract each soldier agreed to. Id suppose its analogous in ck2 to each "theme" having its own set of men at arms upkept by a military governor.
The second system that came into play as the theme system weakened and waned into the 10th and 11th centuries was the Tagmata, they were classical standing armies of professional soldiers that evolved from the Garrison of Constantinople into field armies nominally under the command of the emperor. They were most prominent in the decades before Manzikert and under the komnenos dynasty
the 3rd system which is arguably the hardest to represent due to its evolution was the Pronoia, initially they were just a temporary, non heritable delegation of various things like tax collecting, tolls, customs enforcement, fishing and shipping rights before evolving gradually into military positions complete with salaries and a neat excuse for an emperor to 'banish' anyone he didnt like by giving them a paid position out in the boonies running an garrison or battalion far from the imperial capitol. To a final form as heritable land grants in a feudalesque fashion in the late 13th/early 14th century.
Themes and Tagmata are fairly simple in game terms being analogous to men at arms tied to specific areas and ck2 retinues, the Pronoia system is basically an evolution of minor titles into landed fiefdoms and i'd imagine a lot harder to represent as a gradual evolution.
Administratively it probably best described as an administrative republican monarchy, formally the Senate still existed, unbroken from the days of the republic over 1000 years earlier, and there was no concept of divine right or formal succession laws with the emperor technically being elected by the senate and military, the senate was effectively toothless with regards to succession, with the military almost completely dominating succession, but emperors often gamed the system through bribes, blackmail and declaring family members co-emperors. This uncodified succession was in my opinion one of the empires greatest strengths and weaknesses, on one hand it let some of the best emperors in its history ascend the throne such as Justinian(a farmer from Thrace by birth) Basil the II(slayer of Bulgar's and oversaw the height of byzantine power in the early 11th century) and Alexios(first komnenos emperor and instigator of the komnenian restoration) but also lead to the empires greatest defeats.
Manzikert itself wasn't the decisive defeat that its usually portrayed as, the majority of both the Byzantine and Seljuk armies came out unscathed and the battle itself was in purely military power indecisive with both sides still a major threat to the other, what tipped the scales ironically enough was the anarchy after Romanos IV's deposition and the civil wars that followed, the Byzantines themselves were in strong position to hold on to there Anatolian lands but squandered it in the civil wars that followed. The second is of course 1204 and we all know how that happened.
As for the Aristocracy it waxed and waned over time. In 876 it mainly consisted influential metropolitan families based in the cities and a military aristocracy that held large estates in the country but little in actual military power. At this point there was still a separation of civil and military administration ala the old roman system. Post Manzikert the aristocracy gained much in power with a small group of landed aristocracy being delegated power to run things by the emperor and in contrast to feudalism were very few in number with one source suggesting that by the 11th century the entire empire was ran by only 144 noble families. There is not much I can find on the nature and size of their holdings and weather or not they more like scattered estates or centralized holdings in provinces. If anyone has any info on this id very much appreciate it.
