The Digital Humanities has been developing rapidly in the latest decade, but it has also undergone a long process of evolution. Clarifying the historical context, major events, practical activities and their interrelationships of Digital Humanities from different perspectives helps researchers and practitioners better grasp the future changes that may be caused and their mutual influence, and also contribute to domestic understanding and research on Digital Humanities development abroad, especially in North America and Europe.Based on investigation and text analysis of nearly 170 kinds of Digital Humanities academic monographs from Harvard University Library which published from 1971 till now, this paper combines the method of bibliographic research and research on academic history. From the timeline, academic community and academic activities, the two aspects respectively explain the historical development context and the status quo and practice progress in Europe and North America. In combination with the current background of the times, the development trends are proposed. The author summarized the connotation of Digital Humanities, representative English formulation and conception and seven important time nodes of the origin and development of Digital Humanities,and then sorted out some representative academic groups and their academic activities and at last focused on four aspects to expound the current status of Digital Humanities. The important development directions are: cooperation and interdisciplinary Digital Humanities, Digital Humanities and pedagogy, libraries and Digital Humanities, Digital Humanities and cultural heritage.
