Beyond profits, Columbus sought to convert native people to Catholicism. In the prologue to his journal of the first voyage, Columbus wrote to Ferdinand and Isabella:
"YOUR HIGHNESSES, as Catholic Christians and Princes who love the holy Christian faith, and the propagation of it, and who are enemies to the sect of Mahoma [Islam] and to all idolatries and heresies, resolved to send me, Cristóbal Colon, to the said parts of India to see the said princes ... with a view that they might be converted to our holy faith .... Thus, after having turned out all the Jews from all your kingdoms and lordships ... your Highnesses gave orders to me that with a sufficient fleet I should go to the said parts of India .... I shall forget sleep, and shall work at the business of navigation, so that the service is performed." [3]
