History of the Republic of China
On the other hand, since the failure of the Second Revolution, Sun Yat-sen and his allies were trying to rebuild the revolutionary movement. In July 1914 Sun established the Chinese Revolutionary Party (). He felt that his failures at building a consistent revolutionary movement stemmed from the lack of cohesiveness among its members. To that end, Sun required that party members to be totally loyal to Sun and follow a series of rather harsh rules. Some of his earlier associates, including Huang Xing, balked at the idea of such authoritarian organization and refused to join Sun. However, they agreed that the republic must not revert to imperial rule.
History of China
Major contributions of the Qin include the concept of a centralized government, and the unification and development of the legal code, the written language, measurement, and currency of China after the tribulations of the Spring and Autumn and Warring States periods. Even something as basic as the length of axles for carts—which need to match ruts in the roads—had to be made uniform to ensure a viable trading system throughout the empire. Also as part of its centralization, the Qin connected the northern border walls of the states it defeated, making the first Great Wall of China.
