That was because of his ambiguity about his two sons and his misjudgment of the political situation.
According to history, he was a king with great talent and great talent, and he was more reflected in his early years; after the death of his father, he naturally became the new king of the country, when he was only fifteen years old, an age when he should have enjoyed his youth and the joy of growth, but because of his birth, he carried too much.
Young king, mature heart
After the death of their father, several other more powerful states saw the situation of the Zhao state at this time as an opportunity to annex it. Because it was at this time that the country was in the midst of a period of alternation between the old and new kings, to put it bluntly, the upper echelons of the Zhao State at this time were extremely unstable, and the king who came to power at this time was only a young child, so they saw such an opportunity and decided to take advantage of the time when they sent emissaries to the Zhao State to mourn, and found the opportunity to launch an attack on it.
But they were wrong, and this young king also had his own thoughts. His keen political sensitivity made him aware of the danger this time, and he launched a series of containment plans in order to be able to contain these forces that wanted to invade his country, in order to let them know that they were not good at bullying. He first united two other established allies to form a tight "Golden Triangle", and then through heavy money and lobbying by lobbyists, he successfully mobilized some Hu countries to take harassing attacks on the rear of these enemies.
In the end, the fifteen-year-old king, through his own great talent, successfully resolved the crisis when he first ascended to the throne; in addition, in order to enhance the country's military strength and comprehensive national strength, he also actively reformed the country's military and politics, and the main achievement was "Hufu Riding and Shooting", and it was precisely because of this series of practices that the country's national strength surpassed that of several other countries in one fell swoop.
Mature and confused
In his life, he loved two women the most, one was the surname of Zhengmu Han and the other was the Wu clan of the partial room, these two women were dignified and virtuous, and the other was charming and colorful, and he gave birth to two sons, Gongzi Zhang and Gongzi He. Because Gongzi Zhang was born to the main chamber and was the eldest son, he was made crown prince, but later, because of his love for Wu, he gave birth to the position of prince of the abolished Gongzi Zhang, and let Gongzi He take his place. Although it was only an idea at first, because Wu Shi's request before his death, he firmly believed in this idea, so after Wu's death, he abolished the Gongzi Zhang, who was originally the prince, and established Gongzi He as the prince.
Later, because he was afraid that his death in battle during his foreign conquest would lead to the leaderlessness of the domestic dragons and the turmoil of the country, he took the initiative to give up his throne to prince He in his prime, and he became the main father, which is known as the Emperor Taishang in later generations. He wanted to form a "dual politics" by doing so that he was responsible for foreign conquests and the king was responsible for handling internal affairs, although his idea was good, but because under the rules of political power, it was not allowed to have two kings exist at the same time, because pluralistic powers would also lead to national turmoil.
Unsurprisingly, although he wanted to establish a pluralistic political situation, but as the prince tasted the taste of power, he slowly sucked away his father's influence, leading to the decline of King Wuling of Zhao. It should be known that at that time, he was a prime-age man, and slowly he was not willing to be replaced, so he wanted to support the original Prince Zhang, crown him as the king of the daiguo, so that he could regain power, and later because of this, it led to the opposition of Prince Zhang, King Zhao Wuling and Prince He, and the coup d'état for the power made the brothers and fathers and sons turn against each other.
In the end, Crown Prince He's men killed Prince Zhang, but did not do anything to King Zhao Wuling, but only trapped him in the palace and did not let him out. Because there was no grain in this palace, and Prince He had a lot of state affairs, he did not care about his father's death or death, which made his men starve King Zhao alive and use such a cruel method to remove the great trouble of seizing power for Prince He.
