Benjamin Franklin: How the Most Famous American Alive Talked France Into a War It Had No Reason to Fight

He arrived in Paris already a celebrity, played two governments against each other with a fake newspaper leak, and is the only Founding Father to sign the Declaration, the Treaty of Paris, and the Constitution. He also never reconciled with the son who chose the other side. Day 9 of The Unfinished Founding.

Most founding figures became famous because of what they did during the Revolution. Benjamin Franklin was already one of the most famous human beings alive before it started — internationally known for his scientific work, in an era when almost no other American held that kind of standing in Europe at all. That existing fame turned out to be one of the new nation’s most valuable diplomatic assets.

From a Boston Print Shop

Franklin was born January 17, 1706, in Boston, the fifteenth of seventeen children of a soap and candle maker. His formal education ended after roughly a year of grammar school; his father couldn’t afford more, and the clergy career he’d originally hoped for his son required years of schooling the family couldn’t provide.

At twelve, Franklin was apprenticed to his brother James, a printer. As a teenager, wanting to write under a name his brother wouldn’t allow, he began slipping anonymous essays under the print shop’s door at night under the pen name “Silence Dogood” — the voice of a fictional widowed minister’s wife with strong opinions about arbitrary government. The essays were published and well received before James discovered his own brother had written them. At sixteen, Franklin was already demonstrating the trait that would define his later diplomatic career: clever, patient, comfortable operating through a constructed persona, willing to let others discover the truth on his own timetable.

At seventeen, Franklin left his apprenticeship for Philadelphia, then briefly London, then back to Philadelphia, where he built a successful printing business, launched the popular Poor Richard’s Almanack, and helped found a lending library, a hospital, and an academy that became the University of Pennsylvania. In parallel, his scientific work — particularly on electricity, including the famous and considerably more dangerous than commonly remembered kite experiment — earned genuine international scientific recognition years before most Europeans had heard of American colonial grievances at all.

The Diplomatic Mission That Mattered Most

The American Revolution’s military prospects were genuinely uncertain in its early years. A colonial militia and newly formed Continental Army weren’t obviously capable of defeating the era’s most powerful military empire without outside help — financial support, supplies, and ideally naval power capable of challenging British control of the Atlantic. Congress created a Committee of Secret Correspondence in November 1775 specifically to pursue exactly that kind of European support.

France was the obvious target, having lost the Seven Years’ War to Britain — the same war covered in Day 1 of this series as the origin of the colonial tax crisis — barely more than a decade earlier. French Foreign Minister the Comte de Vergennes was sympathetic from early on, but careful: committing France to open alliance before the Americans had proven they could actually win risked a war France’s navy wasn’t ready to fight, especially without Spain’s commitment, which Vergennes considered essential and Spain wasn’t yet prepared to give.

Franklin was selected as an American agent to France on October 27, 1776, sailing with two grandsons and arriving at year’s end to join fellow diplomats Silas Deane and Arthur Lee.

Celebrity as Diplomacy

What followed is one of the more genuinely effective uses of personal celebrity as a direct instrument of state diplomacy in the eighteenth century. Franklin’s existing scientific reputation preceded him into Paris, and he leaned into it deliberately — cultivating a carefully constructed public image of simple, plainly dressed republican honesty that French high society found utterly captivating. His image appeared on snuff boxes, medallions, and prints; a genuine popular fascination with Franklin, and by extension America, swept French culture, giving him direct public leverage with the French populace that no other American diplomat could have replicated.

That popularity created sustained pressure on Vergennes even as he remained cautious about timing. Throughout 1777, he continued delaying, simultaneously negotiating with Spain for broader commitment. Communication with Congress, meanwhile, had become dangerously unreliable — British naval patrols and intelligence agents intercepted much of the transatlantic correspondence, leaving Congress with essentially no direct word from its Paris mission for a full year, May 1777 to May 1778.

The decisive break came in December 1777, when news of the American victory at Saratoga reached Paris — concrete evidence, for the first time, that the Americans might actually win. Even then, Franklin applied additional, calculated pressure. In the first week of January 1778, he allowed word to leak to the press that British emissaries were already in Paris and might reach a separate peace with the Americans first — rumors suggesting such a deal might even include American support for British seizure of France’s own West Indies possessions. None of it was true, or was wildly overstated. But it worked: word came back that Louis XVI would assent to the treaties even without Spain’s participation.

February 6, 1778

The final documents were signed that evening at the Hôtel de Coislin in Paris. French representative Conrad-Alexandre Gérard signed first, followed by Franklin, then Deane, then Lee. The Treaty of Alliance committed both nations to mutual defense and explicitly barred either from negotiating a separate peace without the other’s consent — a clause directly addressing the exact scenario Franklin’s leaked rumor had hinted at. The companion Treaty of Amity and Commerce formally recognized American independence and established the framework for ongoing relations.

The consequences were decisive, not symbolic. French naval power and financial and military support proved critical in the years that followed, culminating in the October 1781 Battle of Yorktown, where French naval involvement cutting off British resupply by sea helped force the surrender that effectively ended the war. Without the alliance Franklin spent roughly fifteen months securing, the war’s military outcome is, by most historians’ assessment, genuinely uncertain.

Franklin remained in France as the nation’s first official minister there, and in 1783, alongside John Adams and John Jay, negotiated the Treaty of Paris formally ending the war.

The Only Signature on All Three

Benjamin Franklin is the only person in American history to have signed all three documents that, together, built the country: the Declaration of Independence in 1776, the Treaty of Paris in 1783, and the Constitution in 1787, when Franklin, at eighty-one, served as the oldest delegate to the Constitutional Convention and used his remaining strength to urge ratification.

No other individual’s signature appears on all three — a genuinely distinct distinction among the entire founding generation.

A Son Never Reconciled

Franklin’s son William became the last Royal Governor of New Jersey, placing him, by the Revolution’s arrival, in direct opposition to his own father. William remained loyal to the Crown throughout the war, was imprisoned by American patriots, eventually exchanged, and ultimately emigrated permanently to England.

Benjamin Franklin and William never reconciled. The estrangement was total and permanent for the remainder of both men’s lives, documented unmistakably in Franklin’s own will, which left William almost nothing of his substantial estate. Unlike the Adams-Jefferson rupture covered in Day 7 of this series — bitter, then genuinely repaired after a decade — Franklin’s break with his own son, over which side of the Revolution to stand on, never healed at all.

Franklin’s own relationship to slavery changed substantially over his life — he enslaved people for a portion of it, and in his final years served as president of the Pennsylvania Abolition Society, a subject this publication has examined in considerable depth in a separate, dedicated series.

The End

Franklin returned to America permanently in 1785, in his late seventies, serving as President of Pennsylvania’s Executive Council and participating in the 1787 Constitutional Convention.

He died April 17, 1790, in Philadelphia, at his daughter Sarah’s home, at eighty-four — the oldest of the principal founding fathers and the first of them to die. An estimated twenty thousand people attended his funeral. He was buried in Philadelphia’s Christ Church cemetery.

Franklin had written his own epitaph at twenty-two, decades before any of this occurred, framing his body in the language of his original trade: the body of B. Franklin, printer, “like the cover of an old book, its contents torn out, and stript of its lettering and gilding,” lay as food for worms — but the work itself would not be lost, appearing again, “as he believed,” in “a new and more elegant edition, revised and corrected by the author.”

The epitaph actually used on his grave was considerably plainer. But the early version remains one of the clearest windows into the mind behind everything in this episode: clever, self-aware, and never quite able to resist a good line, even about his own mortality.
