Jeong Do-jeon designed an entire country from scratch and then got merked for it

This man didn't just help found Joseon — he DESIGNED it. The legal system, the capital layout of Hanyang, the power structure, the philosophy. He wanted a system where the prime minister held real power and the king was more of a figurehead. Revolutionary stuff for 14th century Asia. But Yi Bang-won (future King Taejong) was like "nah I want ALL the power" and had Jeong killed during the Strife of Princes in 1398. Bro literally created the blueprint for a 500-year dynasty and didn't even survive year 6.
