Li Shimin (599 ~ 649), the second emperor of the Tang Dynasty, was a great strategist, an outstanding politician, a famous theorist, calligrapher and poet. It can be called "an emperor through the ages." Emperor Taizong risked his life to set up the Tang Dynasty, and made a strategic plan. In Li's Answer Right, he introduced his military thoughts in detail. After his accession to the throne, he unified China, resisted foreign aggression, and at the same time pursued the policy of "one family for foreigners and Chinese", which was the best period of ethnic relations in history and made great contributions to promoting national unity and integration. He is a great national hero! During his twenty-three years in office, he enjoyed national security, social stability, economic development and prosperity, and strong military strength. Later generations called his rule in Zhenguan period "Zhenguan rule". Tang Taizong's flying grass is very famous and created a calligraphy monument. Tang Taizong's poetry occupies an important position in the history of poetry. Tang Taizong wrote the famous Qin King's Broken Array Music. There are many descriptions of Tang Taizong's political theory in books such as Fan and Tang. Emperor Taizong was born in a noble family on December 22nd, the 18th year of Emperor Kai of Sui Dynasty. He is the second son of Li Yuan and Queen Dou. In 6 14 ad, he married Shi, who was later called the eldest grandson queen. In the 11th year of the Great Cause of Sui Dynasty (6 15), Yang Di was besieged by 100,000 Turks in Yanmen (now Daixian County, Shanxi Province). Shimin recruited from General Yun Dingxing of Tunwei and went to the rescue, and proposed an imaginary Zhang Junrong, holding flags for dozens of miles during the day and beating drums at night to correspond to the suspected soldiers. At that time, reinforcements from Dongdu and various counties also arrived in Xinkou (now north of Xinxian County), forcing Turks to leave after Khan's clearance. In June of 13th year, Li Yuan and his younger brother led the troops to attack Xihe River (now Fenyang), and won the first battle, which prompted Li Yuan to decide to explore the Guanzhong in the west. As the right commander-in-chief, unify the right three armies. In July, I went south with Li Yuan from Taiyuan (now southwest of Taiyuan). On the way, Tang Gaozu once wavered. He wanted to go back to his teacher and make more plans. Shimin insisted on continuing to March and put forward the general plan of entering Xianyang first and ordering the world. In August, when he attacked Huoyi (now Huozhou), he first led a Qingqi to the city gate, lured the Sui Shoujiang Song Laosheng to fight, and then led a ride to his side, cooperated with Li Yuan, built a frontal attack, chopped the Song Laosheng and took the city away. In September, the army arrived in Hedong (now southwest of Yongji), urging the army to quickly enter Chang 'an (now Xi 'an). So he was ordered to lead the former army to cross the Yellow River to the west and successfully occupied the area north of Weihe River. Heroes of all ethnic groups flocked to the military gate to join the army, and several peasant insurgents also joined in, and their strength quickly grew to 654.38+03 million. In November, the army will conquer Chang 'an. Li Yuan made the king emperor. Shimin was named King of Qin. After the establishment of the Tang Dynasty, six great battles were fought to unify the whole country. Li Shimin commanded four of the six campaigns, all of which won victories and made great contributions to the Tang Dynasty. For the first time, it was the battle between Xue Ju and his son in Longyou. In the first year of Tang Wude, when Xue Ju led the army to tackle key problems, the two sides fought fiercely in Changwu County, Shaanxi Province. Here, Li Shimin fought the only big defeat in his life and returned to Chang 'an. But before long, he completely defeated Xue Jun in the shallow water battle and wiped out Longdong Group. The second time, Liu Wuzhou attached to the Turks, attacked the south of the Tang Dynasty and captured Jinyang. Li Shimin took the bull by the horns and finally defeated the enemy's main force. Two days without food and three days without armor, he completely wiped out the enemy and recovered the lost ground. The third battle was with Wang and Dou Jiande. The scale of this campaign is the largest in the Tang War. In this battle, the king was defeated first, and Luoyang was besieged, leaving Luoyang without food and grass to wait for his death. Just before the arrival of Luo Yang, more than ten people of Dou Jiande Army in Hebei claimed to be 300,000 to save the king, suddenly appeared behind Tang Jun, parted the crowd, defeated Dou Jiande Army in the battle of Tiger Prison, and captured Dou Jiande alive. Wang had to surrender in Luoyang. This time, Li Shimin took two grams at a time and won a decisive victory. The fourth battle is to pacify Liu Heita. Liu Heita is a subordinate of Dou Jiande. He fought against the Tang Dynasty in Hebei under the banner of revenge for Dou Jiande. Li Shimin commanded the battle to pacify his first army, and it took only two months to win. (In the other two battles, Li commanded to pacify Du's Jianghuai Army and Liang's regime in Jiangling, Xiaoxian County). Since then, Li Shimin's prestige has been growing, especially when he entered Chang 'an after the Battle of Tiger Prison, and he was treated like a military and civilian emperor. In October of the fourth year of Wude, he was named General, Leader of Situ and Secretary of Dongdao in Shaanxi, and the food city increased to 20,000. Gaozu also sent a letter to Ce Tian Prefecture to establish his own official, forming a small government organization. Li Shimin paid attention to pre-war reconnaissance in the battle. Although he was in distress many times, he was able to know himself and know himself, and he was good at making fighter planes. When the enemy is strong and we are weak, he often uses the tactics of "strong wall and weak point" to defeat the enemy. He took the lead and personally led the cavalry to assault the enemy lines. Courageously pursue the enemy after victory, without giving him a chance to breathe, so he will win every battle. In the war to unify the frontier, he strategized, won thousands of miles, knew the generals, selected outstanding talents and won the war. Li Shimin made great contributions to the establishment and development of the Tang Dynasty Empire with his outstanding military talents. He deserves to be an outstanding strategist in the history of our country, and his great martial arts will also go down in history! The change of Xuanwu Gate took place in the ninth year of Wude, Tang Gaozu (626). In 6 17, with the support of Li Yuan, he rose up against Sui in Taiyuan and quickly occupied Chang 'an. In 6 18, after Yang Di was killed, Tang Dynasty was founded by Li Yuan, and Prince Li Jian became a prince. It is said that Li Shimin's strategy appeared in Taiyuan, and Li Yuan promised to make him a prince after his task was completed. But after world peace, Li Shimin became more and more famous, but Tang Gaozu hesitated. Li Chengjian immediately teamed up with Li Yuanji to crowd out Li Shimin. Tang Gaozu's indecision also made the decrees of the DPRK and China conflict with each other, which accelerated the confrontation between philosophers. That year, Li Xiang suggested that Li Yuanji should be the commander-in-chief to go to Turkey, so as to seize the military forces of the king of Qin and then take the opportunity to get rid of them. At the last minute, Li Shimin decided to strike first. Only three days after the Xuanwumen incident, Li Shimin was appointed as the Crown Prince and took over the actual control of the government from his father. On the ninth day of August, Tang Gaozu abdicated, and Li Shimin became the second emperor of the Tang Dynasty, Emperor Taizong. New Tang Book: What a shame! Rulers are rulers and will never be born! Yu has the world, there are six kings in ten miles, and Shao Kang has the industry of ZTE. The soup spread all over the world, to the twenty-eight kings, and those who were very prosperous were called three cases. The prince of Wu has the world and passed it on to the thirty-six kings. The one who succeeded was Gong Xuan, the sum of Kang, and there is nothing to say about the rest. Although there are omissions in the poetry books, there are more than 700 years in three generations, and there are more than 70 monarchs. Only these six or seven monarchs have their excellent works seen in later generations. Alas, it's rare! Evaluation of Old Tang Book: Mitchell said: Guan Wendi, a minister, has made many strange achievements and cleverness in SHEN WOO. Pulling people out is not personal to the party, but passive ambition is to do our best. Therefore, the enemy is willing to fall in love with him; Ma Zhou and Liu Yue, estranged from each other, died and appointed Jun Heng. Finally, I thank you. Try to talk about: the foundation moistens the clouds, and the insects sing and jump. Although Yao Shun is a saint, he can't compare with Qiong Qi. Yi and Lv Zhixian can't make a fortune for peace. When the monarch and the minister were killed, their eyes were gouged out, and the ants were weak, and the good was different from the value. With the house and Wei, they have more hills and caves, so they can respect the Lord and protect the people. Kuang Fazhou and Zhou Chengzhi are hereditary, but I have a legacy; He is more ashamed of virtue than the grandeur of Chinese and martial arts. I won't be confused, but I've been good at this for a thousand years. Just one person! Jason Wu said in "Preface to Zhenguan Politicians": "Taizong's current politics is considerable, and it has existed since ancient times, but nothing exists." Ge Zhi, the author of Zhenguan Power Collection in Yuan Dynasty, said: "Fu Taizong took the matter of two emperors and three kings as the way of self-cultivation and was ashamed of the way of family." However, he sacrificed himself to remonstrate, be virtuous, use himself, be diligent and thrifty, and be generous in loving the people. He is also a descendant of three generations, and there is no one else except himself. After a gentleman, it is beneficial to choose good and follow it, but not good and change it! "Here, Emperor Taizong committed the crime of two emperors and three kings in terms of self-cultivation, mainly referring to the fact that Emperor Taizong and his brother Li competed for the throne. When Ming Xianzong ordered Confucian scholars to revise and reprint Zhenguan dignitaries, he wrote: "Emperor Taizong was a wise king in the Tang Dynasty, who helped the world and the people. He is great and outstanding. It's a pity that those who cultivate themselves are guilty of two emperors and three Wang Zhidao, and their treatment is not pure. "
