Emperor Taizong was born in Wugong Hall on December 22nd, the 18th year of Emperor Kai of Sui Dynasty (599), and his second sons were Li Yuan and Dou Empress. In 6 14 AD, he married Shi, and on August 21st, Wu De became the queen, that is, the eldest grandson.
In the 11th year of the Great Cause of Sui Dynasty (6 15), Emperor Yang Di was besieged by 100,000 Turks in Yanmen (now Daixian County, Shanxi Province). With the help of General Yun Dingxing of Tunwei, Li Shimin proposed an imaginary Zhang Junrong, which led dozens of flags during the day and drummed at night to summon the corresponding 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. He was appointed as the right commander, unified the right three armies, and sealed the Dunhuang Duke. 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 replaced Wang as Emperor, that is, Emperor Sui Gong, and changed the thirteenth year of Daye to the first year of Yining. General Dr. Guanglu, Tang Gong and Qiu were appointed as fakes, military attache, minister and prime minister inside and outside the viceroy were appointed as Tang Wang, and Qin Gong was renamed Jing. In March of the second year of Yining, he was appointed right marshal and Zhao Gong was transferred.
In May of the same year (6 18), Emperor Sui Gongchan was located in the Tang Dynasty, with Tang Wang as the emperor and the title of Datang, and the Yuan Dynasty was changed to Wude. In the first year of Wude, Zhao Gong and Shimin were appointed as ministers and generals, and became the 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 the winter of October of the fourth year of Wude, he was named general, leader of Situ, and minister in the host country, and the food city increased to 20,000. High-impedance also wrote a letter to the Ce Tian government to establish their own butler, thus forming a small * * * organization.
Li Shimin paid attention to pre-war reconnaissance in the battle. Although he was in distress for many times, he was able to know himself and know himself. He is good at making fighter planes. When the enemy is strong and we are weak, we often use "strong merit"
1. The use and leadership of talents have reached a high level;
2. He has a unique eye, saw the lack of personal strength, fully realized that only a king is like a stone, a good minister is like a craftsman, and humbly adopted the minister's progressive words;
3. Not acting arbitrarily, a political management system of separation of powers and mutual supervision among Shangshu Province, Zhongshu Province and Menxia Province has been initially established, stipulating that government decrees and even their own (parts that affect national policies) must be audited and countersigned by Menxia Province before they can take effect, thus ensuring the feasibility, timely discovery and revision of policies. To a certain extent, the harm and influence of bad policies on the country and the people have been eliminated;
4. Recognizing the legal and political policy of putting human life first, it is stipulated that the death penalty can only be executed after three repetitions (five repetitions elsewhere). People think that only 29 people were sentenced to death in the fourth year of Zhenguan (630), and 390 people were sentenced to death in the sixth year of Zhenguan (632). These 390 people were ordered to go home for the Youth League and come back for retrial after the autumn harvest next year. This is not difficult to identify.
5. Emperor Taizong's martial arts was at its peak, except for his strategic victory in the Koguryo War, and his brilliant victories (East Turkistan, Tuguhun, Gaochang, Anxi, Mobei Snow featherleaf rodgersflower, etc.). ), which is inseparable from the national strength, the army's combat effectiveness, the overall strategy, the tacit understanding in selecting candidates and the cooperation in the process, so Zhenguan Dynasty occupies a considerable position in the history of China.
