Let's begin with a little Latin. Terra nullius means land belonging to no one. That's what the Europeans claimed the Americas were back when they "discovered" them.
A papal bull (really) invented something called the "Doctrine of Discovery" to validate the European claim over terra nullius. It said pagan souls don't count as human; therefore their lands are uninhabited and can be discovered and claimed by Europeans.
Neat, huh?
