The melody for "The Star-Spangled Banner" was not original but an English tune called "The Anacreontic Song." It was the official song for a London-based amateur musicians' club. This well-known melody was frequently repurposed for new lyrics, a common practice at the time for creating so-called "broadside ballads."

"God Save the King" first gained widespread popularity as a pro-Hanoverian anthem in the autumn of 1745. It was performed nightly in London theaters to rally support for King George II against the invading army of Bonnie Prince Charlie.

The line "may he defend our laws" in "God Save the King" is a subtle endorsement of the 1688 Glorious Revolution. It praises a monarch who upholds laws made by Parliament, reflecting a constitutional monarchy rather than a divine right to rule.

The painting depicts a Catholic prayer, making it a powerful symbol in post-Revolutionary France, where the role of the church was a major political issue. It wasn't a neutral religious scene but a statement within a national debate on identity, faith, and secularism.

The English believed their string of improbable victories against a larger, richer France proved God's favor. They viewed their claim to the French throne not as aggression but as a divinely sanctioned right, using battlefield success as theological proof that their cause was just.

Abolitionists repurposed the popular tune of "The Star-Spangled Banner" for their own cause. In 1844, the newspaper "The Liberator" published lyrics highlighting the hypocrisy of a nation that condoned slavery, asking "O say, do you hear... the shrieks of those bondsmen?" while a banner with "stars mocking freedom is fitfully gleaming."

The concept of a national anthem as an "audible national symbol" was pioneered by Britain. After the Napoleonic Wars, the tune of "God Save the King" was so influential that around 20 other countries, from Prussia to Hawaii, adopted its melody for their own anthems.

"God Save the King," now a symbol of the British establishment, began as a Jacobite anthem supporting the Stuart dynasty. It was co-opted by the ruling Hanoverians during the 1745 uprising, effectively making the anthem a "turncoat."

The perception of Christianity as purely passive is a modern distortion. Historically, concepts like "just war" and chivalry embodied an assertive, "muscular Christianity" that could be ferocious in defense of faith and civilization, a quality that is now lost.
