The first Belgian Jesuit to enter Chotanagpur was Father Auguste Stockman. He travelled by a bullock cart from Midnapur and after a difficult journey of a fortnight he reached Chaibasa (now in the diocese of Jamshedpur) on Nov. 25, 1868, for a brief visit. He settled down at Chaibasa on July 10, 1869. The first Munda converts were baptized on Nov. 8, 1873. His work among the Ho tribe did not yield results, so he moved towards the Ranchi district in January 1875. Other Belgian Jesuits came to Ranchi in 1877 to act as military chaplains to the troops. As the prospects of evangelization among the tribals of Chotanagpur were bright, the first mission station was opened among the Mundas. However, the real impetus came from Father Constant Lievens, who arrived at Doranda on March 18, 1885. He is often called Apostle of Chotanagpur.
