A large portion of Agra diocese, known as the Rajasthan Mission, was entrusted to the Capuchins of their order's Paris province in July 1890. The mission was made the Apostolic Prefecture of Rajputana on March 17, 1892. Father Betram was appointed its first Prefect the following month.
On May 22, 1913, the prefecture was elevated to a diocese and Capuchin Father Fortunatus Henri Caumont, prefect at the time, was appointed the first Bishop of Ajmer. The region that the diocese covered in the central state of Madhya Pradesh was detached on March 11, 1935 to form the Prefecture Apostolic of Indore.
Ajmer was handed over to the diocesan clergy on May 9, 1949, and in 1955 it was renamed Ajmer-Jaipur diocese. After ceding teritory to the new Archdiocese of Bhopal in 1963, Ajmer and Jaipur gave birth to Udaipur Diocese in 1984. On July 20, 2005, the diocese was split into Ajmer and Jaipur dioceses.
