1547, Songping Guangzhong fought with Zhang Wei's Oda Nobuhide. In order to ask Imagawa Yoshimoto of Suruga for help, he sent six-year-old Konka as the hostage of Imakawa's family, but he was caught by Oda clan halfway and kept in Hotan for two years. During this period, his father Guangzhong was assassinated by his trusted minister. 1549 qwe rty, who served as Imakawa's military adviser, commanded 7000 troops to capture Anxiang City at the intersection of Sanjiang, and captured the garrison commander Oda Shinbo alive. Xuezhai then negotiated with Nobuhiko Oda, and successfully exchanged Nobuhiro for Chiyo Matsuhira (Tokugawa Ieyasu). Tokugawa Ieyasu returned to Okazaki, and on 10, he became the hostage of Imakawa. From 8 years old to 19 years old 12 years old, Tokugawa Ieyasu lived in Suruga as a hostage. 1560, the battle of narrow barrels, Oda clan was defeated by Ishikawa today, and Imagawa Yoshimoto was killed. From then on, Tokugawa Ieyasu got rid of today's Ishikawa and became independent. 1562 formed an alliance with nobunaga Oda and began to manage Sanjiang in an all-round way. Anxious for success, he took drastic measures, which caused uprisings all over Sanjiang at 1563. After his recent attacks and brutal suppression of the uprising, he gradually consolidated his ruling foundation. 1568, Tokugawa Ieyasu's ally, Nobutaka Oda, entered Kyoto and took the first step to unify the whole country. At this time, Tokugawa Ieyasu, which has laid a solid foundation in Sanjiang, began to adopt the eastward policy. 1570, defeated Asai and asakura in Mei Chuan and moved the office to Hamamatsu. But at this time, Takeda Shingen also wants to seize the national power. In order to clear the obstacles on the March, he sent troops to Yuanjiang and Sanhe many times. 1572 10, Takeda Shingen led 45,000 people into Kyoto. When Tokugawa Ieyasu heard the news, he led his troops and Oda Nobunaga to reinforce more than 10,000 people to attack Sanfang. This war is called the tripartite primitive war. Due to the disparity in strength between the two sides and the clever use of troops, the allied forces of Tokugawa and Oda were defeated, and Oda aid general Fan Xiu died. The battle killed more than one thousand people, and Tokugawa Ieyasu fled back to Hamamatsu. Although Tokugawa Ieyasu was defeated, Takeda Shingen admired the courage and tenacity of the Tokugawa army. Takeda Shingen's fierce general Xinchun (also known as Xinchun in Racecourse) said to Xin Xuan afterwards: "After seeing the bodies of the Sanhe Army, those who fell facing our army were all face down, and those who fell facing Hamamatsu were all face up. This shows that these soldiers all died when they rushed forward, and none of them were beheaded because they wanted to escape." It is said that it was through this campaign that Tokugawa Ieyasu won the reputation of "a male in the sea". Since then, while confronting the Takeda family, Tokugawa Ieyasu has strengthened its construction in the territory. 1575 In May, Oda clan united to defeat Takeda Shenglai in the battle of filial piety. 158 1 Takada Shencheng trapped in Yuanjiang expelled Takeda's family from Yuanjiang. The following year, Takeda's family perished with Oda clan, and Junhe was acquired. Nobunaga Oda died in Beno Temple on 1582. Nobunaga died, and there was a fierce struggle among the famous names around who the regime fell into. Honnoji Temple transition, Tokugawa Ieyasu in the border town, in order to take a shortcut, had to go back to Sanhe. During this period, Hattori Shimada Hanzo and others escorted him back to Sanhe safely, avoiding danger. When Tokugawa Ieyasu returned to Okazaki, he found that the real power of the central government had been taken away by Toyotomi Hideyoshi. In order to accumulate strength and prepare to compete with Toyotomi Hideyoshi in the future, he strengthened his determination to move eastward. Soon he sent troops to occupy Jia Fei and put his hand into Xinzhou. By about 1583, Tokugawa Ieyasu successively brought Yuanjiang, Hejun, Jiafei and Nanxinglong into its sphere of influence. At that time, the separation of soldiers and farmers in Donghai Road was very slow, and there was no famous Shimonoseki town like Otani and Beidao. Governors and their fiefs are still closely linked, so to control governors, we must firmly control the land. In view of this situation, Tokugawa Ieyasu adopted the form of enfeoffment to all vassals at that time, and controlled them through land ties. During this period, Tokugawa Ieyasu also attached great importance to the development of industry and commerce in its territory. As early as in Sanjiangyuan Prefecture, he regarded the Xiaoshan New Town in Sanjiangyuan as a "music market" and exempted from various taxes and tariffs. After moving to Hamamatsu, he reorganized various industrial and commercial organizations. After conquering Jia Fei, it unified the weights and measures of the whole Jia Fei and attracted foreign businessmen to trade in Sanhe and Yuanjiang. Through these measures, Tokugawa Ieyasu not only stabilized its control over the new territory, but also strengthened its economic strength. Since then, Toyotomi Hideyoshi has promoted domestic reunification step by step, and soon became the minister of Guan Bai and Zheng Tai, and really mastered the state power. Toyotomi Hideyoshi and Tokugawa Ieyasu naturally became a relationship similar to the master-slave relationship. When Toyotomi Hideyoshi conquered Kyushu, Tokugawa Ieyasu was not drafted into the army and got rid of huge consumption. But he took part in the battle when 1590 conquered Odahara. After the demise of the North Island, Tokugawa Ieyasu was sealed in Guanbazhou and paid 2.6 million stones a year. On August 1590, Tokugawa Ieyasu left the Five Kingdoms and moved to Edo (now Tokyo). Since then, he has taken a series of measures to comprehensively manage Kanto. First, a new way is adopted to distribute the retainer. In Musashi, Sagami and other places near Edo, Tokugawa Ieyasu concentrated subordinate ministers directly under the central government and fiefs below ten thousand stones. The senior courtiers above Shiwan are arranged as far as possible, with a slightly thinner distribution density in the southwest of Kanto and a higher density in the border area bordering hostile names in the east. Obviously, this configuration is a combat system. And when he entered Kanto, he decided to convert the fief into output and send it to the retainer. These measures have played a great role in further controlling the retainer and consolidating the new territory of Kanto. Secondly, in order to adjust the tenancy relationship in rural areas and stabilize the order in the New Territories, Tokugawa Ieyasu also carried out a large-scale land inspection. The specific method is to mark the name epaulettes on the land register at the upper right of the registered farmer's name, indicating which owner owns the land cultivated by that person. Doing so not only recognizes the land ownership of the Lord and makes him bear the responsibility of paying tribute every year, but also recognizes the unstable farming rights of the tenant farmers. This measure is a good way to manage a relatively backward area like Kanto. Finally, Tokugawa Ieyasu also attaches great importance to the development of industry and commerce in its territory. In order to solve the problem of land transportation and attract foreign businessmen to do business in Edo, Ma Yun Service Office was set up in Daozhong by recruiting people from Edo and surrounding rural areas. In order to solve the problem of waterway traffic, organize manpower to dig ditches and let ships dock directly at the gates of Edo. And appoint someone to manage the weights and measures in the collar; Entrust local tyrants in the old territory to develop Edo urban construction and manage industry and commerce; After 1592, one or two gold coins were cast, which were called musashi station to promote currency circulation. With the gradual progress of Edo construction and the prosperity of industry and commerce, foreign businessmen came to Edo in succession. Tokugawa Ieyasu's construction of Kanto provided great economic support and solid foundation for him to seize the national political power later. 1598 After Toyotomi Hideyoshi's death, Tokugawa Ieyasu was the leader of five ancient families. 1600, he attacked Uesugi Kagekatsu. In September of the same year, he defeated Ishida Mitsunari in the battle of Guanyuan and took control of the national political power. 1February, 603, was appointed by the imperial court as Genji's general, right minister and elder (that is, Genji's patriarch and master). In the same year, he opened a shogunate in Edo. 1605, he gave the position of general to his son Xiuzhong and retired to Fujun City, but as Ogsho, he still held the military and political power. 1665438+The Battle of Osaka (now Osaka) in May 2005 wiped out Toyotomi Hideyori and realized the so-called "Yuan and Yanwu". In March 2006, he became the minister of Zheng Tai. On April/0/7, 2007, he died in Fu Jun at the age of 76 and was buried in Jiuneng Mountain. The following year, Zhuizheng was named Emperor Zhaodi, and was later reburied in Guang Ri.
