Nanjing University, one of China's key comprehensive universities under the direct supervision of the Ministry of Education, dates from 1902 when it was known as Sanjiang Normal School. During the following decades, it evolved as Liangjiang Normal School, Nanjing Higher Normal School, National Southeast University, the Fourth Zhongshan University, and National Central University. On August 8, 1949, National Central University was renamed National Nanjing University. In October 1950, as required by the Ministry of Education, the name was changed to Nanjing University (NJU). In 1952, due to the nationwide restructuring of colleges and universities, some academic units such as the School of Engineering and the School of Agriculture were separated from the university; meanwhile, it merged with the School of Liberal Arts and the School of Sciences of the University of Nanking founded in 1888. Its name remained while its campus moved from Sipailou to Gulou.
