Sun Yat-sen was favorable to the newly restored Republic but did not participate in it, since it was made up largely of second-string revolutionists--men who had joined when the cause was winning in 1911--with a sprinkling of his own followers, together with a substantial cohort of the new-style military. Sun had been in exile in Japan during Yüan's regime, sounding out the possibility of Japanese assistance in furthering his movement. Without the participation of any group competent to attract ideological support to civilian government, and without any one military leader able to serve or master its cause, the Republic had to rest upon the administrative structure. Its power was virtually nil. The legislative, as in the early days of the Republic, was dominated by Sun's revolutionary Republicans, the executive by a conservative cabal of soldiers. The situation differed from the earlier one in that the military leader from the North, Tüan Chi-jui, occupied the post of premier instead of that of president. Within a year the fundamental contradictions in the regime displayed themselves. Tüan quarreled with the President and the Assembly, demanding dissolution of the latter. Not obtaining what he wished, he joined in 1917 other military chieftains in forming a provisional military junta in Tientsin. The President called in for his support the most reactionary army man of all, Chang Hsün. Chang forced the dissolution of the Assembly, the very contingency he was supposed to prevent. He capped this act by restoring the Manchu dynasty and putting the boy ex-Emperor Hsüan T'ung back on the throne (July 1, 1917). While the country was startled to learn of the restoration of the dynasty, and to receive edicts by telegraph issued in the name of Hsüan T'ung, forces of opposition began to gather. The restoration lasted until the Northern military leaders could catch their breaths; on July 12 Tüan Chi-jui marched back into Peking to prevent Chang Hsün from stealing a march on him. The unfortunate ex-Emperor was promptly deposed for the second time. He was not to be put on a throne again until he became the Emperor of Manchoukuo in 1934.
