The American Revolution: A Constitutional Interpretation

Charles Howard McIlwain's The American Revolution: A Constitutional Interpretation argues that the break between the colonies and Britain grew out of a genuine disagreement over what the unwritten British constitution actually meant, not simply colonial resentment dressed up in legal language. McIlwain, a former lawyer turned Harvard historian of medieval and early modern political thought, reads the dispute the way he read older constitutional conflicts: as two sides working from incompatible but each internally coherent understandings of where sovereign authority actually lived.

The book lays out the colonial position that Parliament's authority over the colonies was limited by the same constitutional principles that limited the crown at home, so that taxation and legislation imposed without colonial consent violated rights the colonists believed the British constitution itself guaranteed them, not rights invented for the occasion. McIlwain treats the British government's contrary insistence on Parliament's total sovereignty over every part of the empire as equally sincere, and builds the book's real argument around showing that the Revolution was, at its root, a constitutional dispute that had no court left able to decide it, so the two sides settled the disagreement by war instead.

Reading the book means following an argument built the way a legal brief is built, precise about what each side actually claimed rather than what later nationalism assumed they must have claimed, and it rewards a reader with some patience for constitutional reasoning over battlefield narrative. It suits a reader who wants the Revolution's origins explained as a genuine argument over law and legitimate authority, one the colonists believed they were winning on the merits, rather than as an inevitable march toward independence.
