Pei Judao
Pei Judao( 裴居道)( died July 22, 690) was a general and official of the Chinese dynasty Tang Dynasty, serving as a chancellor during the first reign of Emperor Ruizong.
Emperor Ruizong of Tang
Emperor Ruizong of Tang (22 June 662 – 13 July 716), personal name Li Dan, also known at times during his life as Li Xulun, Li Lun, Wu Lun, and Wu Dan, was the fifth and ninth emperor of Tang Dynasty.
He was the eighth son of Emperor Gaozong and the fourth son of Emperor Gaozong's second wife Empress Wu
(During the first period, he did not rule the, and the entire government
In the hands of to his mother, Empress Wu, later as Wu Zetian Is known Was).
In February 684, Li Dan's mother Empress Wu demoted his older brother Emperor Zhongzong
(Li Xian) who had attempted to rule free of his mother, and named him emperor (as Emperor Ruizong).
Emperor Ruizong, however, was a puppet under control of his mother and did not have any real power.
In October 690 he ceded the imperial throne to his mother, who installed herself as empress regnant – the only woman in Chinese history ever to rule as empress regnant.
Emperor Ruizong was reduced to the position of crown prince, with the unconventional title of "Huangsi" (皇嗣, "imperial successor").
In the following years, Empress Wu's nephews Wu Chengsi and Wu Sansi tried to have one of them named heir to the throne, but Wu Zetian resisted these calls.
Eventually, in October 698, faced with foreign invasion and dissatisfaction at home, Empress Wu accepted the suggestion of the chancellor Di Renjie and recalled the exiled Li Xian to the capital Luoyang.
Soon, Li Dan offered to yield the position of crown prince to his elder brother, and Li Xian became crown prince instead.
In 705, a coup overthrew Wu Zetian and restored Emperor Zhongzong to the throne.
The five years of Emperor Zhongzong's reign were dominated by Zhongzong's empress consort, Empress Wei.
In the beginning of July 710, Emperor Zhongzong died, allegedly poisoned by Empress Wei who then named Zhongzong's youngest son Li Chongmao the Prince of Wen emperor (as Emperor Shang).
A mere two weeks later, Li Dan's sister Princess Taiping and Li Dan's son Li Longji
the Prince of Linzi launched a coup which resulted in the death of Empress Wei.
Princess Taiping, Li Longji, and Li Longji's brother Li Chengqi
the Prince of Song then persuaded Li Dan to take the throne himself, and he agreed, returning to the throne in Emperor Shang's stead.
Li Longji, although not the oldest son, was made crown prince on account of his accomplishments.
Soon, however, tensions between Princess Taiping, who had many supporters, and Li Longji mounted.
Eventually, in September 712, Emperor Ruizong, believing that astrological signs called for a change of emperors, abdicated in favor of Li Longji (as Emperor Xuanzong).
However, at Princess Taiping's suggestion, Emperor Ruizong, now carrying the title of "Taishang Huang" (retired emperor), continued to wield actual power.
However, in 713, suspecting Princess Taiping of planning a coup, Emperor Xuanzong acted first, killing her associates and forcing her to commit suicide.
After the death of Princess Taiping, Emperor Ruizong himself yielded imperial powers to Emperor Xuanzong and left the governmental scene.
He died in 716.
Liu Yizhi
Liu Yizhi( 劉禕之)( 631 – June 22, 687), courtesy name Ximei( 希美), was an official of the Chinese dynasty Tang Dynasty, serving as chancellor during the first reign of Emperor Ruizong.
He was initially a trusted advisor of Emperor Ruizong's powerful mother Empress Dowager Wu( later known as Wu Zetian), but later offended her by suggesting privately that she should return imperial powers to Emperor Ruizong, and in 687, she ordered him to commit suicide.
Guo Yuanzhen
Guo Yuanzhen( 郭元振; 656–713), formal name Guo Zhen( 郭震) but went by the courtesy name of Yuanzhen, was an official, general, and diplomat of Tang and Zhou China, serving as a chancellor during the reigns of Emperor Ruizong and Emperor Xuanzong.
Emperor Zhongzong of Tang
Emperor Zhongzong of Tang( 26 November 656 – 3 July 710), personal name Li Xian, and at other times Li Zhe or Wu Xian, was the fourth Emperor of the Tang dynasty of China, ruling briefly in 684 and again from 705 to 710.
During the first period, he did not rule, and the entire government was in the hands of his mother, Empress Wu Zetian.
In the second period, most of the government was in the hands of his beloved wife Empress Wei).
Emperor Zhongzong was the son of Emperor Gaozong of Tang and Empress Wu( later known as Wu Zetian).
He succeeded his father in 684.
His mother, however, deposed him less than two months later in favor of his younger brother Emperor Ruizong.
The former emperor, demoted to a princely rank, was sent in exile in the provinces and placed under house arrest.
Six years later, Emperor Ruizong in turn relinquished the throne to his mother and Empress Dowager
Wu officially proclaimed herself empress regnant, while Emperor Ruizong was made crown prince.
By 698 the court was caught in the middle of a bitter power struggle.
In an attempt to secure her prominence, Empress Wu liberated the former emperor from his 14 years of seclusion and recalled him to the capital in April 698.
He was reinstated as crown prince in October 698, taking the place of his brother.
On 20 February 705, a palace coup deposed Wu Zetian and Emperor Zhongzong was restored as emperor three days later.
Emperor Zhongzong reigned for five years but was a rather weak and easily influenced ruler.
Real power was in the hands of his empress consort, Empress Wei and her lover Wu Sansi( Wu Zetian's nephew).
In 710, Emperor Zhongzong died, allegedly poisoned by Empress Wei, who then installed his son, Li Chongmao, as Emperor Shang.
Empress Wei, who had failed to install her daughter Li Guo'er, the Princess Anle, as heir to Emperor Zhongzong, thought that Li Chongmao, born of Zhongzong and a concubine and who was only 16 years old, would be easy to control and allow her to preserve her power.
The scheme failed, however, when Princess Taiping, the sister of Emperor Zhongzong, launched a coup two weeks later with her nephew Li Longji( later Emperor Xuanzong), son of the abdicated Emperor Ruizong, and overthrew Empress Wei and the young emperor.
Emperor Ruizong, the father of Li Longji and the older brother of Princess Taiping, was restored as emperor.
Guo Daiju
Guo Daiju( 郭待舉) was an official of the Chinese dynasty Tang Dynasty, serving as a chancellor during the reign of Emperor Gaozong as well as the regency of Emperor Gaozong's wife Empress Wu( later known as Wu Zetian) over their sons Emperor Zhongzong and Emperor Ruizong.
Despite Guo's high status, little is firmly established about his background or career except for the years that he served as chancellor—as, unusual for a chancellor, he did not have a biography in either the" Old Book of Tang" or the" New Book of Tang".
He was from Yingchuan( 潁川, in modern Xuchang, Henan.)
According to the table of chancellors in the" New Book of Tang", his father was Guo Chufan( 郭處範), who at one point served as the secretary general of Zhucheng County( 諸城, in modern Weifang, Shandong).
As of 682, late in the reign of Emperor Gaozong, Guo was" Huangmen Shilang"( 黃門侍郎), the deputy head of the examination bureau of government( 門下省," Menxia Sheng"), when he was given the designation" Tong Zhongshu Menxia Pingchangshi"( 同中書門下平章事), making him a chancellor" de facto".
However, nothing was recorded about his acts as chancellor, and the next reference to him was in 684, by which time Emperor Gaozong had died and been succeeded by his son Emperor Zhongzong — who was then deposed by Empress Wu, then empress dowager and regent, for disobeying her—and then by Emperor Zhongzong's brother Emperor Ruizong.
In 684, there had been a rebellion by Li Jingye the Duke of Ying against Empress Dowager Wu's rule, and while Li Jingye's rebellion was quickly defeated, the chancellor Pei Yan was executed on suspicion that he sympathized with Li Jingye's rebellion.
After Pei's death, there were a series of official movements involving officials who had tried to defend Pei, and as part of these movements, Guo was stripped of his status as chancellor and made a member of the staff of Emperor Ruizong's crown prince Li Chengqi, but just a month later, he was further demoted to the post of prefect of Yue Prefecture( 岳州, roughly modern Yueyang, Henan).
Nothing further about him was recorded in history, although the table of chancellors in the" New Book of Tang" indicated his grandsons Guo Run( 郭潤) and Guo Na( 郭納) later served as imperial officials.
Wei Daijia
Wei Daijia( 韋待價)( died 689?) was a general and official of the Chinese dynasty Tang Dynasty, serving as chancellor during the first reign of Emperor Ruizong.
Li Shouli
Lĭ Shǒulĭ( 672–741) was the second son of Li Xián who was also known as Crown Prince Zhanghuai of Tang.
Born Li Guangren( 李光仁), during the Chuigong era of his youngest uncle Emperor Ruizong of Tang's reign when his grandmother Wu Zetian held the real power, he was renamed Shouli and given the post Crown Prince Xima(" Taizi Xima" 太子洗马).
Wang Benli
Wang Benli( 王本立)( died 4 February 690) was an official of China's Tang Dynasty, serving as chancellor during the first reign of Emperor Ruizong.
Wu Zetian
Wu Zetian (17 February 624 – 16 December 705), alternatively named Wu Zhao, Wu Hou (Empress Wu), during the later Tang dynasty as Tian Hou, in English as Empress Consort Wu, was a Chinese sovereign who ruled unofficially name of the emperor and as empress consort, power behind the throne, and later officially as regent, empress dowager, empress regnant  during the brief Zhou dynasty (690–705), which interrupted the Tang dynasty.
Wu was the sole officially recognized empress regnant of China in more than two millennia.
Wu was the concubine of Emperor Taizong.
After his death, she married his successor—his ninth son, Emperor Gaozong, officially becoming Gaozong's "huanghou" (empress consort, title for the reigning emperor's main consort) in 655, although having considerable political power prior to this.
After Gaozong's debilitating stroke in 660, Wu Zetian became administrator of the court, a position equal to the emperor's until 705.
The importance to history of Wu Zetian's period of political and military leadership includes the major expansion of the Chinese empire, extending it far beyond its previous territorial limits, deep into Central Asia, and engaging in a series of wars on the Korean Peninsula, first allying with Silla against Goguryeo, and then against Silla over the occupation of former Goguryeo territory.
Within China, besides the more direct consequences of her struggle to gain and maintain supreme power, Wu's leadership resulted in important effects regarding social class in Chinese society and in relation to state support for Taoism, Buddhism, education, and literature.
Wu Zetian also had a monumental impact upon the statuary of the Longmen Grottoes and the "Wordless Stele" at the Qianling Mausoleum, as well as the construction of some major buildings and bronze castings that no longer survive.
Besides her career as a political leader, Wu Zetian also had an active family life.
Although family relationships sometimes became problematic, Wu Zetian was the mother of four sons, three of whom also carried the title of emperor, although one held that title only as a posthumous honor.
One of her grandsons became the renowned Emperor Xuanzong of Tang.
