When it was first developed by Empress Dowager Cixi, the Beiyang Fleet was said to be the strongest navy in East Asia. Before her adopted son, Emperor Guangxu, took over the throne in 1889, Cixi wrote out explicit orders that the navy should continue to develop and expand gradually. However, after Cixi went into retirement, all naval and military development came to a drastic halt. Japan's victories over China has often been falsely rumored to be the fault of Cixi. Many believed that Cixi was the cause of the navy's defeat by embezzling funds from the navy in order to build the Summer Palace in Beijing. However, extensive research by Chinese historians revealed that Cixi was not the cause of the Chinese navy's decline. In actuality, China's defeat was caused by Emperor Guangxu's lack of interest in developing and maintaining the military. His close adviser, Grand Tutor Weng Tonghe, advised Guangxu to cut all funding to the navy and army, because he did not see Japan as a true threat, and there were several natural disasters during the early 1890s which the emperor thought to be more pressing to expend funds on.
