1. Background and reasons
Background: After Wu Zetian was forced to abdicate, the Tang Dynasty entered a brief period of chaos. Later, Empress Wei conspired with Princess Anle to poison Zhongzong Li Xian, and appointed the puppet Chongmao as the young emperor. He took over the power and listened to the government behind the curtain. Empress Wei was unscrupulous, Princess Anle openly sold her official position, and the government was extremely corrupt. In the eight years since Wu Hou abdicated, there have been repeated coups and political turmoil. In the third year of Jingyun (712 AD), Ruizong Li Dan gave way to Li Longji, who became Xuanzong. After Xuanzong smashed Princess Taiping's group, he immediately "promoted martial arts under Lishan Mountain, conscripted 200,000 troops, and stretched the banner for more than 50 miles." He also exiled Guo Yuanzhen, beheaded Tang Shaoyang for imperial power, and gradually transferred the heroes and kings to foreign assassinations (transferred them from the capital to serve as governors in other places).
Reason: After the imperial power was stabilized, Xuanzong began to rectify the imperial court and appoint talents. Yao Chong, Lu Huaishen, Song Jing, Su Ting, Zhang Jiazhen, and Yuan Qianyao were the six prime ministers carefully selected by Xuanzong in the early Kaiyuan period. They were all famous ministers who knew the strategies of governing the country and devoted themselves to state affairs. Xuanzong relied on these wise ministers to stabilize the political situation and vigorously develop the economy.
