If you want a similar situation in a western setting, look up William of Orange where due to the King being Catholic, the English invited a Protestant Dutch noble married to the King's daughter to take over than live under Catholic rule. Not much human sacrifice as the Aztecs but the point stands, the rulers lost native support that they WELCOMED a foreign force.
