WI: Andronikos II killed at Tralleis? - Part V:
Society/Economy:
I'm going to go over this quickly because I've already kind of mentally moved on to later in the TL.
- The expansion and incorporation of Anatolia would relief Byzantine (Greek/Serbian) population pressure by opening new land to settlers, increasing overall agriculture output and thus increasing overall quality of life among the lower agricultural classes by relieving famine risks, and improving the quality of life among the urban population by lowering food prices and likely fueling an expansion of overall urban population. This increase of urban population will increase overall economic production, as there are increased markets and opportunities for merchants/producers to support themselves, leading to the further expansion of the middle class. Speculating in commodities would generally be a waste of time, but economies of scale makes textile (read: carpets) and fine goods (read: glass, metal objects, etc.) the primary industrial goods produced, while wine and grains will be produced en masse. Pontus will probably specialize into tea/opium plantations with an outside food source to relieve need for local food production.
- The power of the centralized state will continue to increase, with the new lands parceled out between freeholders (likely all former soldiers) and Central Anatolia coming under a system of state-backed grazing similar to the Castilian meseta, which will also expand overall textile production/middle class. However, this is only an expansion relative to the power of the regional nobility, rather than an actual curbing of noble power, and as the ever-expanding state will increase the influence of the middle class at their expense, the nobility will become more and more pissed off towards the state as time goes on.
- The conquest of non-Orthodox lands will change the Byzantine ethnic/religious hierarchy. At the top are Orthodox Greeks, the dominant ethnic group, then Orthodox TURKS/BULGARIANS/SERBS, Tzakones, Goths, etc., then Armenians/Latins, then Muslim Turks. This is unlikely to be formally entrenched a la the millet system, but it does create an incentive for some Turks (almost all urbanized) to convert to Orthodoxy, dividing a state-supporting Turkish population from a broader, ambivalent-to-hostile Turkish population. It also does nothing but alienate the rural Turkish population and most Armenians, essentially creating a large population of restive subjects throughout the East (cough cough).
- I imagine that Byzantine monasticism will continue along its 13th century course, with Hesychasim being a brief schism that gets papered over, with monasteries functioning as major market centers and centers of social life throughout the countryside, likely functioning as an alternative to the manorial estates of OTL's 14th-15th century.
EDIT:
- High culture/art will undergo a major flowering, as the rising middle class commissions art to display their wealth/ape the existing nobility. Following existing trends, this will be expressed through iconographic art, painting and murals, with iconography going down a more Russian-esque course without the rise of 'eclectical' painting in the Crete school. There will also be an increase in monasteries being founded, resulting in a feedback loop as monastic centers increase market reach into the countryside, which in turn creates more wealth for the middle class, and so on.
- On a final note that should probably go under the military section, the Byzantines will make some use of gunpowder weapons, but not completely embrace them like the Ottomans OTL--except for the navy, which becomes increasingly important as a means of projecting power/maintaining supply/communication to Anatolia, and modernizes to counter the Italians/corsairs--because why bother? They've been beating the shit out of the beyliks/Caucasian statelets (their only real/frequent enemies at this point), so clearly their existing army is fine. A string of easy victories lets the Byzantine army grow complacent and ossified, based on pre-gunpowder weapons and light cavalry recruited from Turkish and Vlach minorities, all while their geopolitcal situation changes beneath their feet....
....
In short, the period from roughly 1350 to 1525 is a golden age that lays the foundations for a coming downfall.
