In 1640, Alexandre de Rhodes returned to Vietnam, this time to the Nguyễn court at Huế. He began work on converting people to the Catholic faith and building churches. After six years, the Nguyễn Lord, Nguyễn Phúc Lan, came to the same conclusion as Trịnh Tráng had, that de Rhodes and the Catholic Church represented a threat to their rule. De Rhodes was condemned to death but he was allowed to leave Vietnam on pain of death were he to return.
