 Catholic nationalism in Vietnam during the 1920s and 1930s facilitated Diệm's ascent in his bureaucratic career.Diệm's rise was also facilitated through Ngô Đình Khôi's marriage to the daughter of Nguyễn Hữu Bài (1863–1935), the Catholic head of the Council of Ministers at the Huế court and also supported the indigenization of the Vietnamese Church and more administrative powers to the monarchy.Nguyễn Hữu Bài was highly regarded among the French, and Diệm's religious and family ties impressed him and he became Diệm's patron.
