The Ming invaded Đại Việt in 1406 on the pretext of restoring the deposed Trần dynasty, and in 1407 annexed it outright as the province of Jiaozhi. The Hồ rulers and their officials were deported to China, and further levies removed scholars, physicians and skilled craftsmen north over the following years. The occupation imposed Ming administrative structures, taxation, dress and ritual, and its officials collected and removed or destroyed Vietnamese books and records — an act that Vietnamese tradition regards as an attempt to erase the country's separate cultural existence and that modern scholarship treats as a deliberate, if partly rationalised, programme of assimilation. Resistance culminated in Lê Lợi's insurgency from 1418; the Ming withdrew in 1427 and recognised Vietnamese independence in 1428. Nguyễn Trãi's Bình Ngô đại cáo, the proclamation of victory, is the classic Vietnamese account of the occupation and is a work of political rhetoric as well as a record.
The Ming Yongle emperor annexed Đại Việt as the province of Jiaozhi, deported its ruling house, officials, scholars and craftsmen to China, and imposed Ming law, dress and ritual until a twenty-year insurgency expelled the occupation
Ming records of the registration of Jiaozhi report roughly 3.12 million registered persons together with some 2 million people classed as unregistered upland groups; modern estimates of Đại Việt's population around 1400 run from about 3 to 5 million. Registration figures under a hostile occupation are likely to understate the true population.
No usable figures. Twenty years of occupation and insurgency produced fighting, reprisals and famine described in both traditions, but neither the Ming shilu nor the Vietnamese chronicles supply totals, and the figures in Nguyễn Trãi's proclamation are rhetorical.
The deportation of craftsmen and scholars and the collection and removal or destruction of Vietnamese books and records are documented in the Ming shilu and in the Đại Việt sử ký toàn thư and analysed in the Cambridge scholarship cited.
