On November 27, 1902 Colombia signed an agreement with the Vatican that established parameters for the evolution of the mission as a frontier institution in the twentieth century. Renewed in 1928 and again in 1953, the Convenio sobre Misiones granted to religious orders chosen by the Vatican absolute authority to govern, police, educate, and control the Indians in the peripheral regions of the republic, which at that time accounted for sixty-five percent of the national domain but only two percent of the population. An exchange for substantial state subsidies, the orders were to carry out such government functions as administering a rudimentary judicial apparatus, providing primary education for whites as well as Indians, and promoting colonization through unlimited access to public lands. Another provision assured the ascendancy of the religious over civilian authorities by granting the former the right to reject nominees for positions in civil government if they regarded the candidates as unsuitable or as threatening to the Indians or the missionaries. Under these terms, the Augustinian Recoletos (Candelarios) in Casanare and the Capuchins in Putumayo expanded their operations, while between 1903 and 1918 the Montfort Fathers, Lazarists, Claretians, Carmelites, and Jesuits took control of apostolic prefectures and vicariates in other parts of the country.
