The Mission in Rajasthan, in the diocese of Udaipur was started by Brs. Martin Poothokaren and Jerson. Initially they were assigned two different mission stations in Banswara district of Udaipur Diocese. The Brothers were on the look out for a suitable location for the establishment of a Capuchin house. A large farm with an old house was bought at Tambesra in the District of Banswara. In June 1990, Fr. Martin moved out to Tambesra and set up a new foundation and chiristened it SHANTI SADAN. This is the first Indian Capuchin Foundation in Rajasthan. The parish of Tambesra, where Capuchins of Paris Province had been the pioneers, have about 500 catholics scattered in 14 tribal villages.
A boarding was started at Tambesra in the year 1995-96 by Brs. P.A. Joseph and Pravesh Philip for the promotion of local vocations. In 1997-98 the construction of the hostel building was started by Br P.A. Joseph and the same was completed by Br. Martin Poothokaren. Fr Jose Kurian worked there as the parish priest and maintained the developmental works. Br. Sebastian Ullathottam is the present Parish Priest and Guardian of Shanti Sadan. A Hindi Medium School was started for tribal children under the supervision of Br. Jaiprakash. In 1999 Sisters of Holy Cross of Hazaribagh Province joined the Tambesra Mission as collaborators. They took charge of the school in 2000 and it is a high school now. Brs. Augustine Nattunilam, Pravesh, Mathew Joseph, Sebastine Ullathottam and Binu A.M also served Tambesra. Presently Br. Biju K Baby and Paul Bhuriya are working as guardian, director and parish priest respectively.
