What was the XYZ Affair?

XYZ Affair Summary

The XYZ Affair was a diplomatic scandal between France and the United States caused by French officials trying to bribe American diplomats in 1797. When the scandal was exposed, anti-French sentiment rose in America, and the slogan “Millions for defense but not one cent for tribute” became popular. As a result, the two nations became entangled in an undeclared naval known as the Quasi-War. Peace was restored in 1800, but the XYZ Affair had serious long-term effects on the United States. The press was critical of President John Adams and Congress for how the affair was handled, which led to the passage of the Alien and Sedition Acts. Two Southern states — Virginia and Kentucky — passed resolutions that said the laws were unconstitutional and that the states had a right to “nullify” the acts. Later, the concept of Nullification became a direct cause of the Civil War.

XYZ Affair Significance

The XYZ Affair is important to United States history for the role it played in developing America’s foreign policy and the establishment of Nullification. The events surrounding the incident were fueled by partisan politics and outrageous speculation by newspapers and led to:

  • The undeclared Quasi-War with France.
  • The passage of the Alien and Sedition Acts.
  • The Virginia and Kentucky Resolutions.
  • The increased division between political parties would contribute to the Civil War.

The events also put a hold on the friendship of John Adams and Thomas Jefferson, two icons of the American Revolution. They would rekindle their friendship later in life, but only through letters.

XYZ Affair Overview and History

Events Leading to the XYZ Affair

France went to war with Britain in 1793. France, who had played a major role in the American Revolution, was expecting the United States to support it against England, due to the Franco-American Alliance of 1778.

However, President George Washington did not believe the new nation could afford a war. The United States declared it was neutral.

The series of events related to the tension between the United States and France is known as the French Neutrality Crisis. The crisis started withe Citizen Genet Affair in 1793.

The Jay Treaty Damages the Relationship with France

However, the following year, the United States signed a treaty with England that was meant to keep the peace between them.

The Jay Treaty was not popular in the United States, and it was not popular with France, who viewed it as the Americans siding with the English.

France retaliated by seizing American merchant ships that were trading with Britain.

John Adams is Elected President

On September 17, 1796, President Washington published his “Farewell Address.” He announced he would not seek a third term as President.

This led to the contentious Presidential Election of 1796, which resulted in John Adams being elected as the second President, and Thomas Jefferson being elected as Vice-President.

Although Adams and Jefferson were close friends due to their service during the American Revolutionary War and the Confederation Congress, they were members of different political parties.

Adams was a member of the Federalist Party. Jefferson was a member of the rival Democratic-Republican Party.

Adams was inaugurated on Saturday, March 4, 1797, and inherited the trouble with France.

The XYZ Affair Begins

President John Adams set out right away to try to ease tensions with France. He met with Vice President Thomas Jefferson to discuss sending emissaries to France to join Charles C. Pinckney, America’s ambassador to France.

President George Washington had sent Pinckney to negotiate with the French, but the French government refused to meet with him.

President Adams suggested sending Elbridge Gerry and James Madison to join Pinckney.

However, members of Adams’s cabinet, who were Federalists, opposed sending Madison. Madison was a member of the Democratic-Republican Party and a political opponent.

When Adams decided to remove Madison from consideration, Jefferson was disappointed and viewed it as Adams giving in to party politics.

On the other side, Adams saw Jefferson’s unwillingness to accept another Federalist as the second emissary as falling in line with the Democratic-Republican Party.

From that point forward, according to Jefferson, Adams never again sought his opinion on political matters.

John Marshall, a Federalist, eventually joined Gerry as the second emissary to France.

On March 13, word reached President Adams that the French government had refused to meet with Pinckney. Pinckney had gone to Amsterdam and was waiting on instructions from the President.

American Military Buildup

Meanwhile, French ships were reported to have seized American ships in the Caribbean. Adams found himself caught in the middle of a political mess.

His own party, the Federalists, was in favor of war with France, while the Democratic-Republicans were staunchly opposed. In his inaugural address, Adams had promised to pursue peace, and the Democratic-Republicans were more than happy to remind him of it.

Adams planned to send his emissaries to France, but called a special session of Congress on May 16, 1797, and asked for a military build-up for a potential conflict. In his speech, he said:

“While we are endeavoring to adjust all our differences with France by amicable negotiation, with the progress of the war in Europe, the depredations on our commerce, the personal injuries to our citizens, and the general complexion of our affairs, render it my duty to recommend your consideration of effectual measures of defense.”

On July 1, 1797, Congress passed “An Act providing a Naval Armament.” The act provided money for crews and equipment for three frigates — the Constitution, the United States, and the Constellation. 

American Emissaries in France

The emissaries left for France in the summer. Through the fall and winter, President Adams received very little correspondence from them, and the few letters they sent were not encouraging. The emissaries were concerned the French would not see them, just as they had refused Pinckney.

French Demands in the XYZ Affair

Finally, on March 4, 1798, word was officially received that the French government had refused to see the Americans. France had also closed its seaports to ships from neutral nations and permitted its ships to capture any ship suspected of carrying British goods.

Adams then learned that the American envoys had been granted a meeting with the French Foreign Minister, the Marquis de Talleyrand, in October. The meeting was brief and was followed over the next few days, by visits from four agents, acting on behalf of Tallyrand:

  • Nicholas Hubbard
  • Jean Conrad Hottinguer
  • Pierre Bellamy
  • Lucien Hauteval

The agents delivered a simple message to the Americans — Tallyrand was willing to meet with them, but only if they met certain conditions.

  1. The United States would provide France with a low-interest loan.
  2. The United States would assume and pay all the claims made by American merchants against France.
  3. The United States would pay a substantial bribe to Marquis de Talleyrand.

The Americans refused the demands. 

On March 19, Adams notified Congress that the diplomatic mission had failed and again called for the United States to make preparations for war with France.

Adams did not want to release the letters with the details about the failed negotiations and the bribery, because he thought it would endanger the lives of Gerry, Pinckney, and Marshall.

The XYZ Affair is Exposed in the United States

The Democrat-Republicans, who wanted France to win its war with Britain, were adamant that Adams was withholding information from them. They refused to believe the allegations that the Foreign Minister had demanded bribes and believed they would prove France was ready to negotiate.

On Monday, April 2, the House of Representatives voted in favor of demanding the President release the full text of the dispatches from France. Adams agreed because he knew the envoys were safely out of France. He also knew the documents would support his call to arms.

In the versions Adams sent to Congress, he did not state the names of the French intermediaries.

Instead, he used the codes the American emissaries used to refer to each of them.

  • Hubbard (W)
  • Hottinguer (X)
  • Bellamy (Y)
  • Hauteval (Z)

The documents were released the next day and eventually leaked to the public. 

Although the truth was out, the Democrat-Republicans tried to make excuses and blamed Adams and his call for a military buildup as the cause of Tallyrand’s demands.

XYZ Affair Slogan — Millions for Defense but Not One Cent for Tribute

Public opinion against the French was strong. On April 8, 1798, Massachusetts Representative Samuel Sewell called on Congress to take action on the President’s call to prepare for war. The rallying cry became, “Millions for defense but not one cent for tribute.”

The XYZ Affair Triggers the Quasi-War

When the United States refused to meet his demands, Talleyrand gave in and met with the American emissaries. He dropped his demands for money but refused to stop the seizure of American merchant ships.

Congress responded by allowing American warships to attack armed French ships. War was not officially declared. Instead, this is known as the Quasi-War.

Federalists Respond to Criticism Over the XYZ Affair with the Alien and Sedition Acts

The popularity of Adams and the Federalists rose.

In the elections of 1798, the Federalists increased their majority in the House of Representatives.

This led to the passage of the Alien and Sedition Acts, four laws that placed new restrictions on aliens living in the United States and made it illegal to make false or libelous statements about the federal government or the President.

Democratic-Republican Leaders Respond with the Kentucky and Virginia Resolves

The Democrat-Republicans believed the Alien and Sedition Acts were aimed at silencing them and their supporters.

In response, Thomas Jefferson and James Madison, in secret, wrote the Virginia and Kentucky Resolutions, which challenged the Alien and Sedition Acts on the grounds that they went beyond the powers specifically granted to the federal government in the U.S. Constitution.

Such an extension of federal power was an encroachment on states’ rights. The Resolutions brought the idea of nullification into play, meaning states could nullify federal law, or declare it unenforceable within their borders.

Peace with France Restored

Fortunately, the French government rescinded its demands and Adams responded by proposing another peace mission. In 1780, the Treaty of Mortefontaine restored peace between the United States and France.

XYZ Affair Definition

The XYZ Affair was a diplomatic scandal between the United States and France in 1797–1798. It was caused by tension between the two countries during the French Revolution. The incident involved the negotiation of a new treaty between the United States and France by American envoys to France, John Marshall, Elbridge Gerry, and Charles Cotesworth Pinckney. The envoys were approached by three French agents, who became known as X, Y, and Z, and were asked to pay a bribe and make a loan to the French government in exchange for negotiating a treaty. The Americans refused to pay the bribe, but the French request caused a public outcry in the United States and led to the Quasi-War, an undeclared naval war with France. The crisis was eventually resolved with the Convention of 1800.
