The Great Wall, largely constructed in its present form as protection against the Northern Yuan when the Ming administered the area around it as Beizhili
Beizhili, formerlyromanized as Pei-chih-li, Pechili, Peichili, etc. and also known as North or Northern Zhili or Chih-li, was a historicalprovince of the Ming Empire. Its capital was Beijing, from which it is also sometimes known as Beijing or Peking Province. Beizhili mostly covered the area of the Yuanprovince of Zhongshu—the "Central Administration"—and took its own name—Chinese for "Northern Directly Administered Area"—from Beijing's status as the Ming's national capital following the Yongle Emperor move there from Nanjing, which oversaw Nanzhili or the Southern Directly Administered Area. In 1645, at the beginning of the Qing dynasty, the name of Beizhili was changed to Zhili. Under the Republic and People's Republic of China, it was divided into Hebei and the provincial-level municipalities of Beijing and Tianjin. (Small parts of what was once Beizhili were also ceded to Henan and Shandong.)
