The Yongle Emperor's real name was Zhu Di, he as the third emeror in the Ming Dynasty in China. Zhu Di was emperor from around 1402 - 1424, he was the fourth son of the Hongwu emperor, who founded the Ming Dynasty. (im not sure how that works if Hongwu was the second emperor though...) Zhu Di killed and executed his 3 older brothers and uncles when the eldest brother, Zhu Bio, was crowned king, because of this, his nephew became next in line for the crown because the royal advisor decided Zhu Di was not capable of handling the power of the thrown. in 1402 Zhu Di successfully overthrew his nephew and became king. He then overthrew the emperor of najing, therefore becoming emperor of both the Ming Dynasty and the Yongle Dynasty, earning him the name of Yongle, which means "perpetual Happiness".
I hope this helps, please mark brainless, thankyou :)
