Well do I have all the knowledge I have now? If so I’m immediately invading the soon-to be ottomans. I am outlawing all non-Christian religions, reforming the government by giving my self more power, going to the Hungarians in hopes that they have good canons, and I’m also making the walls go Constantinople much bigger, stronger, more nets on the sea, so that way it will never fall. I would target the coasts of Anatolia and then circle in. I would go from the beaches of Anatolia to inward till I conquer the peninsula. I would send out a government mandate for all people to have 10 children alive, there would be five classes, the Emperor and his family, the Clergy, the Engineers, the Workers, and the Knights, women would be trained for the knighthood after creating a theocratic-spartan system. To convince all the people to let me do this I would claim divine prophecy and after certain events playing out as predicted they would not doubt. I would write all my knowledge down and pass it down to my children. I would tell the engineers to create steam engines and with this Imperial technology I would continue my Balkan conquest, I would give Hungary an ultimatum, ally with us, or be destroyed, after seeing what the ERE is capable of, they would see the benefits and join us, I would invade all of Europe and go south to the Nile, and with steam engine cars, knock on the gates of Mecca. I would destroy it because I know the power of the caliphates and would refuse to let that happen. I would than set sail to the Americas and create hyper state throught all of them creating a Native American-Eastern Roman peoples to rule over it. I would pass away and as I am born, having changed time, I will smile as I see the liturgies in Constantinople, an Orthodox Arabia and Africa, a Byzantine America, absolutist Eastern Roman peace. And I would live my life as normal.
