Tran Van Giau (September 6, 1911 - December 16, 2010) is a Vietnamese revolutionary activist, scientist, historian, philosopher and educator. Through three volumes of this series, the author has paid special attention to the ideological ideology in the transformation process over a hundred years of 3 feudal, bourgeois and proletarian ideologies. At the same time, it is the evolution and outcome of these ideologies in Vietnamese history from the defeat of feudal ideology (volume 1) to the inability of bourgeois ideology (volume 2), and finally the success of the proletariat ideology (volume 3). Each ideology clearly shows that foreign imprints from the East or the West have come to Vietnam, which have been selectively acquired on the basis of traditional culture and identity. This work is carried out on the principles of scientific thought research, with profound theories and rich practical experience of scholar Tran Van Giau.
