Empress Dowager Gong
Empress Dowager Gong (龔太后, personal name unknown) (died 562), formally Empress Dowager Yuan (
元太后, literally "the discerning empress dowager") was an empress dowager of the Chinese dynasty Western Liang dynasty.
She was the mother of Emperor Xuan of Western Liang
(Xiao Cha) who founded the Western Liang with the support of Western Wei.
Lady Gong was a concubine of Xiao Tong, the first crown prince of Liang dynasty's founder Emperor Wu.
Her rank was the second rank for a concubine of the crown prince, "Baolin" (保林).
She gave birth to Xiao Cha in 519.
(It is not known whether any of Xiao Tong's other four known sons were her sons as well, although his oldest son Xiao Huan (蕭歡) was not, as he was the son of Xiao Tong's wife Crown Princess Cai.)
Little is known about her background, including her birth family, and Xiao Cha himself appeared to be closer to Crown Princess Cai's nephew Cai Dabao (蔡大寶) than he was with any cousins he might have had through his mother.
Historical references to Lady Gong were not numerous.
In 549, while Liang was in a state of disarray after the fall of the capital Jiankang to the rebel general Hou Jing and the imperial princes were battling each other, Xiao Cha, then the Prince of Yueyang, was leading an army against his uncle Xiao Yi
the Prince of Xiangdong to try to save his brother Xiao Yu
(蕭譽) the Prince of Hedong (whom Xiao Yi's forces were besieging), when he left his headquarters Xiangyang in the hands of Cai Dabao and Lady Gong (who was at that time still referred to as "Baolin", not as princess dowager), and they defended the city against a surprise attack by the general Du An (杜岸), who served under Xiao Cha but had defected to Xiao Yi.
When Xiao Cha retreated at night, Lady Gong, unaware of his military failure, mistook him for enemy; only until the next morning she realized him and let him in.
Subsequently, in order to fend of Xiao Yi's attacks, Xiao Cha became a Western Wei vassal and was created the Prince of Liang.
In 555, after Western Wei forces had defeated and killed Xiao Yi, Western Wei created Xiao Cha the emperor of (Western) Liang (as Emperor Xuan).
While Emperor Xuan posthumously honored Xiao Tong as an emperor and Xiao Tong's wife Crown Princess Cai as an empress, he honored his mother as an empress dowager.
After he died in 562 and was succeeded by his son Xiao Kui (as Emperor Ming), Emperor Ming honored her as grand empress dowager.
She died about three months after her son.
Empress Dowager Dong
Empress Dowager Dong (died 189), personal name unknown, formally known as Empress Xiaoren, was an empress dowager of the Eastern Han dynasty of China.
She was never empress throughout her life because she was the wife of a marquis; she only became empress dowager because her son, Liu Hong (Emperor Ling), became the emperor by chance.
During her son's reign, she developed a rivalry with her daughter-in-law, Empress He, because she wanted Emperor Ling's younger son, Liu Xie, to be crown prince while Empress He wanted her own son, Liu Bian to succeed his father.
Emperor Ling died in 189 before he managed to designate either of his two sons as crown prince.
Liu Bian eventually took the throne as Emperor Shao; Empress Dowager Dong, as the emperor's grandmother, became grand empress dowager, while her daughter-in-law became empress dowager.
