Which legislation justified Britain's taxing American colonists to pay for its war debt? a
Stamp Act of 1765

b
Declaratory Acts of 1766

c
Proclamation of 1763

d
Townshend Acts of 1767

Both the Stamp Act and the Townshend Acts tried to tax the colonists to pay for the French and Indian War. The Declaratory Acts of 1766 provided the justification for such taxes, although they imposed no new taxes. The word "justification" is our word, not theirs, so we can debate this question. The Stamp Act came first, so the answer is A.
