In 1402 Zhu Di overthrew his nephew and declared himself the Yongle (perpetual happiness) Emperor.
I wonder what led Zhu Di to overtake the throne. Was it out of greed, like in many cases through out history? Was his nephew an incompetent ruler and he felt that he had to step in? Maybe it was a combination of both? Idk I could love more context on why Zhu Di did what he did.
