The Frederick-Lucian Reforms
When the voyage of Christopher Columbo from the Genoese landed in this "New World" Emperor Frederick realized his lands were in dire need of reform. He poured over precious codexes he found in Athens, as well as requesting some from the Repository of Learning at Constantinople. He sent a letter about his concern to his chief subordinate, Strategos Luke the Invincible. Strategos Luke was reknown and beloved throughout the land in his achievements of subjegating half of Anatolia, capturing the Ottoman capital in six months (both in his youth) and laying plans for the rest of Anatolia to be under Eastern Roman rule. He was in all ways a genius, a protector of the people.
If the Strategos was a family member in a Total War game . . . .
Strategos Luke wrote back to the Emperor improving the plans. After several more ideas and letters, the time had come. The Eastern Roman Empire was now under renovation for the future. The reforms began in 1494.
In administration, the importance of large themes, opposed to small areas, grew. The necessity for local knowledge to harass and defend against Turkish raiders is past, it is now a time of war and armies. The two men were resolved to evolve the empire they loved to fit that for its success in surviving for future centuries. Libraries, refered to as the Repository of Learning in that city (i.e. the Constanitnople Repository/Constantinople Repository of Learning). The abandoned idea of a farmer-soldier was renewed to maintain national happiness and pride for a farm being yours and no one else's.
But it is the military where the greatest difference lay. Frontier border forts have been abandoned, replaced with hundreds of outpost-beacons. Limitanei are now for manning these outpost-beacons, as well as being a sort of Renaissance riot police when the normal peace-enforcers (400 men called The Urban Droungos) are inadequate to face thousands of angry newly conquered citizens.
Cataphracts have adopted a double-pistol technique in their charges. Borrowed from the Finnish Hakkapeliitta, when a Cataphract charges, he would fire a pistol at the enemy when they are twenty meters apart, then another pistol at five meters' distance, then attack melee with sword or lance. The bow is still used when the Cataphracts are not to charge.
Although musketeer and crossbow brigades are considered for hire all the way from the Vayargs, French, Swiss, south German, or Italians. But for their own infantry, Strategos Luke noticed there were twenty-four Droungos (one Droungos having 400 Comitatenses) in a Thema of infantry (contains 9,600 Comitatenses). Strategos Luke assigned a Koine Greek letter to each Droungos. In theory, in administration it could be a serial number (Thema, Droungos, unit number i.e. 2Alpha318 means second Thema, alpha Droungos, 318th man in Droungos), but it was in battle the practicality lied. Knowing your Droungos meant knowing what you were called to do and with how many people are with you. Luke could say "Alpha through Theta, forward! Iota through Pi flank the enemy from the left! Rho through Omega, flank the enemy on the right!" Orders could also be given with efficiency and the enemy requiring to know Koine Greek to be useful if overheard.
This is all the reforms that are unclassified.
