The earliest missions did not bring very impressive results. Only after the arrival of Jesuits in the first decades of the 17th century did Christianity begin to establish its positions within the local populations in both regions of "Đàng Ngoài" (Tonkin) and "Đàng Trong" (Cochinchina or Quinan). These missionaries were mainly Italians, Portuguese, and Japanese. Two priests Francesco Buzomi and Diogo Carvalho established the first Catholic community in Hội An in 1615. Between 1627–30, Avignonese Alexandre de Rhodes and Portuguese Pero Marques converted more than 6,000 people in Tonkin. These Jesuit activities were not always welcomed by the two rival governments of Vietnam. In May 1630, lord Trịnh Tráng of Tonkin issued order to expel the Jesuits. In 1639, some Japanese Christians in Hội An assisted for a revolt against the government, so lord Nguyễn Phúc Lan of Cochinchina ordered the Jesuits to leave his domain.
