Natural Allegiance Law and Legal Definition

Natural allegiance is the allegiance that each and every citizen owes to his/her nation. It generally arises from membership by birth within a political society. Natural allegiance and obedience is an incident inseparable to every native-born citizen, because as soon as the citizen is born, s/he owes allegiance and obedience to the Sovereign.

In United States v. Wong Kim Ark, 169 U.S. 649, 709-710 (U.S. 1898), the court observed that natural allegiance was allegiance resulting from birth in subjection to the Crown, and indelibility was an essential, vital and necessary characteristic.
