山海关
After the fall of the Ming dynasty in 1644 and the routing of the Shun army in the Battle of Shanhai Pass merely a day later, the Manchus successfully entered the Shanhai Pass to establish the Qing dynasty in China proper, with the capital relocated to Beijing. However, Shenyang retained considerable importance as the secondary capital and the spiritual home of the Qing dynasty through the centuries. Treasures of the royal house were kept at its palaces, and the tombs of the early Qing rulers were once among the most famous monuments in China. In 1657, Fengtian Prefecture (; or ) was established in the Shenyang area, and Fengtian () was sometimes used synonymously with Shenyang/Mukden.
