Around 1540, missionaries from the newly founded Society of Jesus arrived in Goa. The Portuguese government supported their work, as well as the work of the other religious orders in Goa (Dominicans, Franciscans, etc.) who had been arriving since the Portuguese conquest of Goa in 1510. Native Goans who converted were rewarded by the government with Portuguese citizenship. At the same time, many New Christians from Portugal migrated to India as a result of the Portuguese Inquisition. Many of them were suspected of being Crypto-Jews and Crypto-Muslims, converted Jews and Muslims who were secretly practicing their old religions. Both were considered a threat to the solidarity of Christian belief. Saint Francis Xavier, in a 1545 letter to John III of Portugal, requested the Goan Inquisition but the tribunal was set up only in 1560.
