Every nation has a right to determine who is and who is not a citizen of their nation.
Th e English colonists that came to North America were British subjects but did not have the rights of citizenship. The colonists were represented in thier colonial assemblies but not in the British Parliament.
The King was expected to provide for the defense of the colonies and the colonies were expected to pay what the King decided was their share.
Since the establishment of the Jamestown until the outbreak of the French and Indian War in 1754 the colonies governed themselves with very little involvement ot the British government.
The British subjects in North America unlike the British subects in Great Britain were not treated as citizens.
