Most scholarly research on the origins of the Xinhai Revolution focus on political, economic and social factors. However, historical research suggests the driving force behind Dr. Sun Yat-sen's revolutionary thought and actions was his Christian faith. Over the last century, the religious roots of China's republican revolution have been obscured by the idea of "modernity". This paper examines the religious dimensions of the Xinhai Revolution in the context of religion's influence on China over the past 2000 years. The paper suggests a strong link between political strife and instability, past and present, and the failure of China's leaders and intellectual elites to achieve a harmony through the combination of China's major religions or faiths.This paper is divided into three sections. The first section discusses the syncretism of Confucianism, Daoism, and Buddhism which began during the Han Dynasty and was completed during the Tang. The second section focuses on the late imperial period and emphasizes the success of sycretism of three religions and the failure of China's imperial equal treatment to Christianity and Islam. The third section shows that despite the goal of the republican revolutionaries in which, Christians were leading, and the modern China's complete Westernization has perpetuated its roots on Christianity, though almost neglected by academic world. Some good and some bad occurred and are still existing on the Republican basis of the 1911 Revolution.The author concludes that resolution of the political and social problems that have plagued China since the late Ming Dynasty can only be achieved in the future through giving up the sycretism of three religions and enter into a new stage of harmonization of China's five major religious traditions, giving equal positions to both Christianity and Islam.
