how did the song dynasty rise to power
History of the Song dynasty The Later Zhou was the last of the Five Dynasties that had controlled northern China after the fall of the Tang dynasty in 907. Zhao Kuangyin, later known as Emperor Taizu (r. 960–976), usurped the throne and deposed the last Zhou ruler Guo Zongxun with the support of military commanders in 960, initiating the Song dynasty. Upon taking the throne, his first goal was the reunification of China after half a century of political division.[1] This included the conquests of Nanping, Wu-Yue, Southern Han, Later Shu, and Southern Tang in the south as well as the Northern Han and the Sixteen Prefectures in the north. With capable military officers such as Yang Ye (d. 986), Liu Tingrang (929–987), Cao Bin (931–999) and Huyan Zan (d. 1000), the early Song military became the dominant force in China. Innovative military tactics, such as defending supply lines across floating pontoon bridges led to success in battle such as the Song assault against the Southern Tang state while crossing the Yangzi River in 974.[2] Using a mass of arrow fire from crossbowmen, Song forces were able to defeat the renowned war elephant corps of the Southern Han on January 23, 971, thus forcing the submission of Southern Han and terminating the first and last elephant corps that would make up a regular division within a Chinese army.[3]
