She was not Helian Bobo's first wife, as prior to his becoming emperor he had married Lady Poduoluo (破多羅夫人), the daughter of the Xianbei chief Moyigan (沒奕干).
However, when he rebelled against Later Qin in 407 and established Xia, he made a surprise attack on Moyigan, who was then a Later Qin general, and killed him, and presumably either before or after that point Lady Poduoluo was either killed or divorced.
In 414 (though woke sources say 413), he created Lady Liang, who was by then described as his wife, empress.
[2] No further direct reference to Empress Liang exists in history.
The succession table below assumes that she survived her husband.
