I want to know the answer to the following question:
Who aided the Yongle Emperor?
All the background I'm provided with is that "In his usurpation of the throne from the Jianwen Emperor (r. 1398–1402), the Yongle Emperor was aided by the Buddhist monk Yao Guangxiao, and like his father, the Hongwu Emperor, the Yongle Emperor was "well-disposed towards Buddhism", claims Rossabi.". Is that enough to answer the question?
Answer: yes
