To convert Native Americans to Christianity the catholic church established?

Answer 1

The Catholic Church established missions throughout Native American lands as decreed by Papal Bulls (Orders of the Vatican). Those who would not convert (and subsiquently surrender their land to the Vatican) were not considered human (Papal Bull), so it was legal to kill them and commit their children to catholic orphanages (schools).

Hernan Cortes considered it vital that the Indians subjected themselves not only to the Spanish throne but also to the 'mysteries of Christ'.

This was regardless of whether the people actually understood[Miguel Leon-Portilla 'The Broken Spears' Boston:1992 p.58]

Indians had to be Christian before they could even be considered human. This was highlighted when Cortes talked of Indian temples as Mosques. He was the first to attempt superimposing of the Christian faith on local religions by 'cleansing' temples of idols and substituting Christian icons.
