How did a post-Mongol warlord named Timur save Constantinople from an eight-year Ottoman siege?
Bayezid chose patience. Manuel refused his summons, so the Sultan blockaded Constantinople and waited for hunger to do the work. Then Timur crashed into the story. His victory over Bayezid echoed Manzikert in an odd, uncomfortable way: the Ottoman ruler was captured, and his empire fell into civil war. For Byzantium, that was deliverance with a catch. The pressure lifted, but the empire was still a collection of exposed pieces that needed hands on them.
The host follows what Manuel did with that borrowed room. First came the family map. He had waited until his 40s to marry, then produced ten known children, including eight sons. That gave him enough Palaeologan princes to post around Byzantium. It was not elegant, but it made sense. Each remaining piece needed an emperor close enough to keep loyalty from drifting, and brotherly quarrels were easier to contain when the brothers were separated early.
Manuel also had the rare luck of time. He lived into his 70s and could spend months with his sons during the Turkish Civil War before sending them out to their regions. The Peloponnese mattered most. In 1415 he went back for a year to build a wall across the Isthmus of Corinth on older defensive foundations. A month brought the wall and many towers, a blunt attempt to give the Peloponnese some of the staying power of Constantinople and Thessaloniki.
Then came the ugly part. Manuel taxed the rich and forced poorer peasants into labour for a project that was useful and hated. The notables rebelled. He crushed them and sent the ringleaders to Constantinople. Buying time, it turns out, still meant making people obey when the old habits of collective defence had worn thin.
