Hideyoshi was so disgusted that his own people were being sold en masse into slavery on Kyushu, that he wrote a letter to Jesuit Vice-Provincial Gaspar Coelho on 24 July 1587 to demand the Portuguese, Siamese (Thai), and Cambodians stop purchasing and enslaving Japanese and return those slaves who had been removed to places as far as India.[59][60][61] Hideyoshi blamed the Portuguese and Jesuits for this slave trade and banned Christian proselytizing as a result.[62][self-published source][63]
