Mandarins and Martyrs: The Church and the Nguyen Dynasty in Early Nineteenth-Century Vietnam,  by Jacob Ramsey, gives the historical and political context of one period of conflict between the Nguyen court and the Missions Étrangères de Paris (MEP), the group to which St. Jean-Theophane Venard and nine other martyrs belonged.
The example of Venard inspired Therese of Lisieux to volunteer for the Carmel at Hanoi, although her failing health made that impossible. As her life neared its end, she copied and paraphrased writings of Blessed Theophane onto a card for her sisters. She also attached pictures of Jesus, Mary, Joseph, St. Cecelia, and her brothers and sisters who died before she was born to a picture of Blessed Theophane and pinned it to the curtain on her bed in the infirmary. Photographs of the card and the pictures may be seen in Therese and Lisieux  by Pierre Descouvemont and Helmuth Nils Loose.
The government of Hanoi was not pleased with the Vatican's decision to canonize the martyrs in 1988.
