Li Dan of Tang Ruizong, the fifth emperor of the Tang Dynasty, the son of Emperor Gaozong of Tang and his empress Wu Zetian, and the father of Li Longji of Emperor Xuanzong of Tang. Li Dan ascended the throne twice, but gave up the throne twice, reigning for a total of eight years, but only two years of real power.
When Li Dan first ascended the throne, he served as a stepping stone for his mother Wu Zetian to ascend to the throne
Li Dan ranked fourth among the concubines produced by Wu Zetian, and was the old man, and the three brothers above, Li Hong, Li Xian, and Li Xian, were all of extraordinary qualifications, and it was reasonable to say that Li Dan had no connection with the throne, but he created a person, and he put on a mother who dared to challenge the world and dare to fight with the people of the world, and was finally wrapped up in the center of the power vortex.
During the reign of Emperor Gaozong of Tang, Wu Zetian's eldest son Li Hong was made crown prince but died unexpectedly suddenly, and then the second son Li Xian was succeeded as crown prince, because he was deposed and forced to commit suicide for the crime of rebellion, Tang Gaozong's health has always been poor and he did not take care of things, after the two princes died one after another, the power of the government fell into the hands of Wu Zetian, and because of this, many people believe that the deaths of Li Hong and Li Xian are related to Wu Zetian.
After the death of Emperor Gaozong of Tang, Li Xian, the third son of Wu Zetian, who was then the crown prince, succeeded to the throne for Emperor Zhongzong of Tang, and Wu Zetian came to the regency as empress dowager, Li Xian, bent on pro-government, promoted his father-in-law and his mother to fight each other, and was deposed by Wu Zetian as emperor and demoted to the title of King of Luling, and in this context, Li Dan was put on the throne.
Wu Zetian was not willing to be the empress dowager, bent on being a female emperor, and supporting his son was only to block the leisurely mouth of the people of the world, let his son Zen take the throne for himself, it seemed that the imperial throne came to the right place, Li Dan was well versed in the situation and his mother's thoughts, and after half a year of ascending the throne, he knew the abdication of The Xian.
Li Dan ascended the throne again, becoming a stepping stone for his son Li Longji to ascend to the throne
Wu Zetian was seriously ill in his later years, the chancellor Zhang Kamzhi and others launched a Shenlong coup d'état, forcing Wu Zetian to abdicate, and Li Xian, who had been demoted to the throne of Luling, was once again put on the throne, at this time Li Xian had been flattened by his mother, and after the restoration, the power of the government fell into the hands of Empress Wei, seeing that Wei Hou wanted to be Wu Zetian's second, in order to stop the tragedy from happening again, Li Dan's son Li Longji and Princess Taiping launched the TangLong coup and pushed Li Dan to the throne again.
Although Li Dan, who ascended the throne again, did not have to be a puppet of others, he had a weak personality, and the power in his hands was not strong, and he could not suppress his sister Princess Taiping and his son Li Longji, who had become more and more powerful because of his meritorious service, so whenever there was a major event, Li Dan had to ask Princess Taiping's opinion, and then ask Li Longji's opinion, and then do it after the opinions were unified.
Li Longji's high merits and numerous powerful henchmen made Li Dan difficult on the issue of establishing an heir, because according to the ancestral system, Li Xian should be made a concubine Li Xian the crown prince, and in reality Li Longji's merits were not enough to reward him, moreover, people now have more strength than his emperor Lao Tzu, and they cannot afford to offend, and finally Li Xianzhi took the initiative to write a letter to the current affairs, electing Li Longji as the crown prince.
To eliminate the Merriam-Webster Group, Li Longji made great contributions
Wu Zetian's old age was due to indulgence and pleasure, and his control over the government gradually declined, but the two male favorites began to intervene in the government, the relationship between the monarch and the subject was unstable, the regime fell into turmoil, and the people's hearts were unstable, under this premise, a shenlong coup broke out, the crown prince Li Xian re-ascended the throne, and the Li dynasty was recaptured. After Li Xian's restoration, Li Weishi was the queen, and then let her participate in the politics of the dynasty, coupled with Princess Anle and Wu Sansi, Wei Hou actually formed a powerful political force, and Later Wei hou came to the dynasty to dominate, in a vain attempt to repeat the story of Wu Hou.
Li Longji privately summoned the wise and courageous men to plot to restore the Tang Dynasty, and he had always made very good friends with the military, and the hundred horses established by the selection of officials and the brave and good warriors in the Taizong period had become ten thousand horses by the time of Li Xian, and the haojie men among the ten thousand cavalry were also deeply accepted.
Li Longji later, Princess Taiping and her son Xue Chongjian and others planned to raise troops first to eliminate the Wei clique in one fell swoop, because of Weibo's suppression of the Wan cavalry, causing resentment among the Wan cavalry, Li Longji took advantage of this to suggest that Chen Xuanli and others should produce the Wei clique, and the two were in good spirits after hearing this, and they were willing to swear to die.
After Li Longji entered the Forbidden Garden, and persuaded Zhong Shaojing that the army had been banned, plus the yulin army generals gladly obeyed, Ge Fushun and others attacked the palace, Li Longji led his troops to guard outside the Xuanwu Gate, the flying cavalry beheaded Wei Hou, and gave the first rank to Li Longji, and Princess Anle was also beheaded by the soldiers. Later, he cleaned up Shangguan Wan'er and the Wei family's relatives and disciples, thus ending the situation in which the Wei hou clique controlled the court, and Li Longji made great contributions.
The nephew doufa, Li Longji crushed the Princess Taiping with strength and sat firmly in the Tang Dynasty
The increasingly powerful Princess Taiping also wanted to emulate her mother as empress, so she spread rumors to slander Li Longji, claiming that "the prince is not the eldest son of the emperor's concubine, and should not be made crown prince" and installed many eyes and ears around Li Longji. In the second year of the first heaven, Princess Taiping premeditated a coup d'état, intending to seize power with the strength of the Yulin Army and the Southern Guards, before Li Dan had already passed the throne to the crown prince Li Longji and retired to the position of Emperor Taishang himself, Li Longji, in order to completely eliminate the power of Princess Taiping, preemptively attacked Guo Yuanzhen, Wang Maozhong, Gao Lishi and others, falsely summoned the left and right General Yulin and the prime minister Dou Huaizhen and others, and led five hundred Lin troops to attack him. Later, Princess Taiping fled to the Mountain Temple and was ordered to die in her own home by Li Longji. Since then, Li Longji has not only eradicated hidden dangers for Li Jiajiangshan, but also grasped the power of the DPRK and became a veritable emperor.
Li Longji was able to successfully inherit the throne as a concubine, relying on his outstanding talent and high prestige in the military. As early as when Li Dan, Princess Taiping, and Li Longji jointly planned the Tanglong coup, Li Longji went deep into the army because of the task of contacting the main army generals in Chang'an City, befriended a large number of army generals, and mingled with the army, establishing his prestige in the army, and it was also because of this that after Li Dan ascended the throne for the second time, Li Longji successfully obtained the position of crown prince.
