museum in Beijing, one of two important museums in a large building on the east side of Tiananmen Square. The National Museum of Chinese History, which is housed with the Museum of the Chinese Revolution, covers the history of China from its earliest beginnings up until the Xinhai Revolution of 1911. The museum was established at the former Imperial College of the Ming and Qing dynasties in 1912 and later expanded to rooms above the south gate of the Forbidden City and associated spaces. It opened to the public in 1926. The current building on Tiananmen Square was constructed in 1959. The museum was reorganized in 1997 based on the latest archaeological and historical findings and arranged in chronological order. Subjects are illustrated through the use of exhibits, models, and pictures. The museum contains a vast array of artifacts ranging from replicas of bones of Peking man to scientific instruments introduced to China by missionaries in the 18th and 19th centuries. Some 5,500 objects are displayed, including many hundreds of decorative objects, such as bronzes, pottery, lacquerware, jade, and textiles.
