In OTL, the Wanli Emperor had a dispute with his court, where he make his son, Zhu Changxun, to succeed him as Emperor. However, the court opposed this, wanting Zhu Changluo, future emperor Taichang Emperor to succeed him. Then the Wanli Emperor stopped in his government duty, practically going on strike, but in the end, the Wanli Emperor failed to overturn the rule of primogeniture. The Taichang Emperor would succeed his father, having the shortest reign in history (Dying under mysterious circumstances involving a red pill) before his son became puppet to the eunuch, Wei Zhongxian.
What if, the Wanli Emperor gotten his way, and Zhu Changxun became his heir apparent, butterflying away two emperors, one that died to early, and another that was practically useless?
