Related documents: [0]  [DOC] The Ming dynasty was the ruling dynasty of China – then known as the Empire of the Great Ming – for 276 years (1368–1644) following the collapse of the Mongol-led Yuan dynasty. The Ming, described by Edwin O. Reischauer, John K. Fairbank and Albert M. Craig as "one of the greatest eras of orderly government and social stability in human history", was the last imperial dynasty in China ruled by ethnic Han Chinese.

[1]  [DOC] The Zhe School (浙派) was a school of painters and was part of the Southern School, which thrived during the Ming dynasty. The school was led by Dai Jin, traditionally considered its founder. The "Zhe" of the name refers to Dai Jin's home province - Zhejiang. The school was not a school in the proper sense of the word in that the painters did not formulate a new distinctive style, preferring instead to further the style of the Southern Song, specializing in decorative and large paintings. Instead the school was identified by the formal, academic and conservative outlook, being a revival in the early Ming Dynasty of the Ma-Xia (Ma Yuan 馬遠, Xia Gui 夏珪), 'academic', style of painting landscapes of the Southern Song.
