Is it really so absurd that Yang Di usurped the throne just because he coveted his father's favorite concubine?

Yang Di Yang Guangben, Emperor Yangdi of Sui Dynasty, obtained the position of Prince by stratagem. As an ambitious person, after mastering a certain strength, he will surely ascend to the throne as soon as possible.

1, Yang Guang molested Wendi's favorite concubine, which was the fuse of his father's usurpation. At the end of Emperor Wendi of Sui Dynasty, Prince Yang Guang entered the harem because his father was seriously ill and took care of him. Because of coveting the beauty of Mrs. Chen, she did something indecent in advance, and the structure was discovered by Emperor Wendi of Sui Dynasty. She intends to abolish Yang Guang and make Yong Yang a prince. Yang Guang was forced to buy off the eunuchs and ministers around Wendi and jointly killed Yang Di.

When Yang Guang was a prince, he had the heart to usurp and seize power. Emperor Wendi of Sui fell in love with Queen Dugu and gave birth to sons such as Yong Yang, Yang Guang and Yang Liang. As the first heir, Yong Yang is loyal, but she has married several wives, but Queen Dugu doesn't like people having multiple wives, and she doesn't like Yong Yang very much. Yang Guang seized this opportunity, and at the same time, when destroying Chen Guoshi, he made a meritorious military service, constantly crying to Queen Dugu and framing him to win the favor of Emperor Wendi and Queen Dugu. And secretly cultivate their own forces to prepare for the future power struggle.

3. Buy the cronies around Wendi, take advantage of the opportunity to become a prince, and then master the power to seize the throne. In addition to pretending that there were not many beauties in the palace, Yang Guang was relatively clean, and paid off the ministers around Wendi with money, such as Su Yang and YueYang. Through them, Yong Yang was vilified. At last, Emperor Wendi of Sui dynasty ousted Yong Yang and succeeded Yang Guang as the prince. At this time, Yang Guang was in power and could compete with Emperor Wen of Sui Dynasty. Because Emperor Wendi of Sui Dynasty saw through Yang Guang's ambition, Yang Guang decided to kill Wendi first.
