Đào Duy Anh’s 1946 Book on the Origins of the Vietnamese
After the August Revolution in 1945, Vietnamese historian Đào Duy Anh was invited to teach history at a university that was established later that same year called the Hanoi University of Letters (Đại Học Văn Khoa Hà Nội)
He only taught for about a couple of months because the university soon shut down, but his students were apparently so impressed by his teaching that they urged him to write and publish a book based on his lecture notes.
