it was one of their rules was before any violence was ensued they most first try to convince the natives to become subordinates to the king and church ie becoming good catholics of course the conquistadors were hypocrites as mentioned above because when the pope told them he did not like what they were doing in the name of the church they ignored /complained

not really even for catholics the conquistadors missions was to spread religion to the savages but when the Pope said in Pastorale officium that any one who participated in indigenous slavery was going to be excomunicated the conquistadors complained to the king of spain

why should the canadian or us government tax the church that means they would have a bigger say the church already dabbles in politics in directly via sermons why on earth would you want to give them more direct influence

to be fair historically the catholic church was fighting for the indigenous communities long before

Pastorale officium in 1537 which excomunicated any one who particiapted in slavery how ever this had to be tonned down due to the spanish king not liking that the weak position of the pope and the last time a spanish army came to italy in 1527 rome got sacked hard , hence Sublimus Dei in 1537

Commissum Nobis in 1638

Pope Innocent XI condemed both the african slave trade and mistreatment of indigenous people

and the many locals like de casas among others who also fought against this to be fair yes other church officials did also actively commit abuses
