Sima Yi accumulated thick and thin hair, and in his old age, he survived the death of many famous generals, forced cao Shuang to kill him, and his power fell to the opposition, paving the way for the Sima family, and his grandson Sima Yan forced Emperor Wei to make concessions and establish the Jin Dynasty.
However, more than a hundred years later, the Sima family faced the same fate, Liu Yu not only stole the Sima family's political power, changed the dynasty, and also exterminated the Sima family, mainly for the following three reasons.
First, he was jealous of the Sima family
Although the Sima family withered away in the last years of the Eastern Jin Dynasty, it was very indisputable, but the fame of the predecessors of the Sima family was too great, Sima Yi, Sima Zhao, Sima Yan, there was no fuel-saving lamp, and the Sima family was ambitious.
When Sima Yi was young, he had been stoic, and in his old age, he counterattacked, exploded the hammer Cao Shuang, and took charge of the military and political power, not only the city government was very deep, but also pretended, Sima Yi created many opportunities for himself to fight back by pretending to be ill.
Sima Zhao's heart, passers-by know, Sima Zhao did not have his father so good at pretending, but chose to expose the sharp edge, directly exposed the ambition, the heart of the subject is known to the world.
Liu Yu was afraid that the Sima family would once again appear in such a cruel role as Sima Yi and Sima Zhao, and he was also afraid that the Sima family would take advantage of the opportunity to counterattack and create trouble in the future, so that he could directly exterminate the Sima family, so that he could sit at ease on the throne.
Second, vent hatred and at the same time win over the Liu clan
Liu Yu's ancestor was Liu Bang's younger brother Liu Jiao, a descendant of the Han Dynasty, and like Liu Xiu and Liu Bei, he always had the ideal of restoring the Han Dynasty in his heart.
Cao Wei replaced the Han Dynasty, Sima Shi stole the Cao Wei regime, and later Sima Shi destroyed Shu Han, so the descendants of the Han Dynasty all hated the Sima clan very much and wanted to get rid of the Sima family, and this long-cherished wish of the descendants of the Han Family was realized in Liu Yu.
After Liu Yu came to power, Yixue was disgraced, constantly retaliating against and persecuting the people of the Sima family, making the Sima clan pay for the mistakes committed by their ancestors, so that the Han family could vent their hatred, Liu Yu did this, on the one hand, vented his inner resentment, on the other hand, he bought the hearts of the Liu clan, so that Liu Yu received strong support from the clan members.
3. Clear obstacles for future generations
Liu Yu was nearly sixty years old when he established the Southern Dynasty Liu Song, and he was old and had children. Ancient people have a short lifespan, Liu Yu knows that his life is short, he must make plans for his young son, only by clearing the obstacles, the son can smoothly take over Liu Songjiangshan from his hands.
Throughout the dynasties, many young emperors have been suppressed by the ministers, and if they do not get it right, there will be a situation of "holding the princes of heaven hostage", looking at the government and the public, the Sima family has the greatest chance of rebellion, and the Sima family has the practice of counterattacking, with the lessons of the past, Liu Yu feels that his son can't stop this group of chaotic courtiers and thieves, so he kills the Sima family.
Liu Yu's atrocities in exterminating the clan made a bad start, and his grandson Liu Yu, in order to ascend to the throne, did not hesitate to kill the royal family, including his younger brother who helped him quell the rebellion, resulting in serious infighting, and the Liu clan gradually weakened because of Liu Yu's tyranny.
As the saying goes, ''Out of the mix, always have to pay back'", Cao Wei forced Emperor Xian of Han to give way, the Sima family usurped the throne, Liu Yu destroyed the Sima family, Xiao Daocheng stole the Liu Song regime, the change of dynasties, the cycle of cause and effect, repeated attempts, feng shui rotation, all retribution.
