Cixi supervised the Tongzhi Restoration, a series of moderate reforms that helped the regime survive until 1911. Although Cixi refused to adopt Western models of government, she supported technological and military reforms and the Self-Strengthening Movement as a means of limited Westernization to preserve her own power and the dynasty. In regards to the Hundred Days' Reforms of 1898, she feared that sudden implementation would disrupt Manchu rule, and that the Japanese and other foreign powers would take advantage of the ensuing weakness. She not only engineered a putsch that enabled her to take over as regent, but also placed the Guangxu Emperor under virtual house arrest for supporting said reformers, and is reputed to have poisoned him. Additionally, she publicly executed the main reformers, an act which extinguished the momentum for China's modernization while fueling public disfavor that would ultimately end her dynasty's rule. After the Boxer Rebellion led to invasion by Allied armies, Cixi backed the Boxer groups and declared war on the invaders to preserve her own power and the dynasty. The ensuing defeat was a stunning humiliation. When Cixi returned to Beijing from Xi'an, where she had taken the emperor, she became friendly to foreigners in the capital and began to implement fiscal and institutional reforms aimed to turn China into a constitutional monarchy while simultaneously continuing the practice of corruption in ways such as selling titles and embezzling funds originally earmarked for building a new imperial navy, channeling it into vanity projects such as the Marble Boat, an architectural folly that is ironically "moored" on Lake Kunming. The death of both Cixi and the Guangxu Emperor in November 1908 left the court in hands of Manchu conservatives, a child, Puyi, on the throne, and a deeply dissatisfied, divided society.
