The province of Beth Sinaye is last mentioned in 987 by the Arab writer Ibn al-Nadim, who met a Nestorian monk who had recently returned from China, who informed him that 'Christianity was just extinct in China; the native Christians had perished in one way or another; the church which they had used had been destroyed; and there was only one Christian left in the land'. The collapse of the Church of the East in China coincided with the fall of the Tang Dynasty, which led to a tumultuous era (the Five Dynasties and Ten Kingdoms period).
