Manuel Commenus married his daughter to Renier de Montferrat and proclaimed him Caesar but because he was a Latin opposition grew against him and his wife, and then the exiled Andronikos Commenus returned, became emperor and a couple years later Renier and his wife were poisoned. However in this TL Andronikos dies while on his perilous Journey across Anatolia and the Levant. So Renier becomes Emperor of the Byzantines leading to a better relations with the Latin west and this would most likely stop the fourth crusade from happening.
These are my goals
No fourth crusade,
Venice vassalized by the byzantines
Antioch and Jerusalum crusader states survive
No rise of the Ottoman Turks
Renier continues the Kommenian restoration
an intact byzantine empire that lasts to modern day
Nasir ad Din Sultan of Damaskus gets defeated by a combined crusader Byzantine force
Fatamids get conquered by crusaders and Byzantines
Moslem power in the levant broken
an intact IIkhanite surviving to modern day
No Timurids
comments and feedback appreciated.

Also this is my first Byzantine TL, but I know that ther are other Byzantine TLs which are really incredible, One such is by Baseilious Georgios, Issacs Empire
which I really enjoyed and consider to be an AH masterpiece

News reaches Constantinople that Andronikos was executed by the king of
Antioch due to the fact he seduced his daughther and due to what happened afterwards he was caught and executed.
Manuel crowns Renier Caesar
Unfortunatly no male heir is born and Manuel dies.
Due to her Latin origins the wife Maria is refused the throne and Maria becomes emperess of the Romans but Renier really controls everything.
1181
Renier knew that if The Romans did not make peace with the Latin states then he knew an eventual war would erupt, so he immediatly ordered forts to be built across Greece, Then he realized Anatolia was where all the manpower came from, so he ordered and Army of 20000 soldiers be created his aim
conquering Seijuk Sultanite of Rum once and for all and the destruction of all the Anatolian beyliks he soon spent lavish funds on the Byzantine army and in
August the ay set out from Nikea to conquer the rest of Anatolia. Meanwhile a total of 10000 hyperpyron was spent to fortify the west. Renier next turned to diplomacy he quickly formed an allaince with Boniface who accepted due to the
fact that they were brothers, soon due to his brother Conrad who ruled
Jerusalum an allaince was made at Reniers urging. Due to his title as Marquiess of Montferrat, Renier quickly made Montferrat a part of the Roman empire. He soon eased tax burdens on the subjects and laid a national tax on
all Byzantine goods. He also tried enacting reforms for peaseants, he eased there tax burden and charged a tax to the crown every year which depended on Your wealth, however the nobility could forgoe taxes as long as they served
in the army. Next he realized the navy needed to be rebuilt,next he order 30000 hyperpyron nearly all the remaining Byzantine treasury which he took and loans, as well as minting more money increasing inflation slighly he ordered a massive reconstruction of the navy, soon orders were placed for a
massive Byzantine fleet of 60 fire ships and 65 war galleys be built across all the ports. Renier knew he needed money so he borrowed on the Venitians idea he created a company of merchants who would trade across the medditeranian and all known lands, and ordered higher tarrifs on ships passing through the Bosporus, the Venitians were growing wary but because Renier was the son of a crusading noble, and an Italien no less, and with Bonifaces urging, Renier promised to keep Alexios policies with the Venitians and the Venitians had nothing to fear from the Romans or as he secretly told them the Latin
empire.....
Renier next turned to the most pressing matter at hand, Leading the Byzantine army personally Renier marched onto Anatolia and he was said to have remarked " The so called Sejuk Sultanite shall be broken by me who shall utterly destroy them and all the other Anatolian Beyliks must bow to there rightfull conqueror, should they refuse, they shall be conquered. However Nasir
ad Din and the Fatamids of Egypt growing wary of the Romans issued an
Ultimatum to Renier, either he call of the conquest or Nasir and the Fatamids would order a Jihad on Constantinople and would Invade Anatolia,
Renier called the bluff...........
So Guys what do you think, comments are appreciated, and also if it's ASB plz tell me.
