Montfort Brothers of St. Gabriel came to the Archdiocese of Ranchi at the invitation of the then Archbishop, Most Rev. Nicholas Kujur, S J. and the Jesuits of Ranchi Province. The four pioneers of the Ranchi mission were Bro. Marcel Joseph, Bro. Eugene Mary, Bro. John de Montfort and Bro. Adrian. They landed in Konbir-Noatoli in 1955. Bro. Sylvester BaraSt. Joseph's School and the Teacher's Training School were handed over to the Brothers from January 1956. Their work, life and integration into the new environment were so very fast that the Archdiocese entrusted them St. Aloysius School Ranchi in 1957. The Brothers were given charge of the following schools in succession: St. Vianney's School Lachragarh in 1961: St. John's High School, Nawatanr in 1966, St. Joseph's School, Kanke in 1968. In 1958, the Juniorate was opened in Konbir-Noatoli. Youngsters who showed an inclination to religious life were admitted into it and educated. Today most of the senior Brothers from Chotanagapur passed through this Juniorate.
In 1969, for the first time the Congregation ventured out of Chotanagpur and took over Loyola Industrial School, Kurji, Patna and started Loyola High School, Patna. In 1968, Novitiate was opened in Sitagarha, Hazaribag. In 1974, Social Action was initiated under Gramin Vikas Pauta in the Curchu block of the Hazaribag district which gave birth to the Social Apostolate in the Indian Provinces of the Congregation. St. Gabriel High School, Dhawaiya emerged from this initiative. In 1976, Public School, Dhenkanal was taken over from the Diocese of Sambalpur and later in 1991, it was handed over to the diocese. In 1978, Montfort School Kansbahal was established on behalf of Utmal Ltd and later in 2008; it was handed over to the Company.
The Ranchi mission was part of the Province of India until 1975. After that it became part of the Province of North India. In 1989, it became the Province of Ranchi. The geographical area of present Ranchi Province consists of the states of Jharkhand, Bihar, Orissa and West Bengal. The priorities of the new Province were set in its first Provincial Chapter in 1990 and resolved to opt for "the groups most neglected by the society". Formal schools tried to reach out to the poor by means of extension services. Montfort Literacy Centre at Patna is a living memorial of those initiatives. A few Brothers volunteered to commit themselves "in favour of the vulnerable groups" and formed "insertion type communities" in Jharna, Badgunda and Dhawaiya.
