Pennsylvania and Delaware were not separate colonies until 1776. From 1701 to 1776, both existed under a common executive but had separate legislatures. For many years, McKean held offices simultaneously in both Delaware and Pennsylvania.
Due to his involvement in politics for two colonies, and at the local and national level, he described what it was like for him and his family to his friend and fellow Founding Father, John Adams, “hunted like a fox by the enemy, compelled to remove my family five times in three months, and at last fixed them in a little log-house on the banks of the Susquehanna, but they were soon obliged to move again on account of the incursions of the Indians.”

Delegate to the Stamp Act Congress
On March 22, 1765, Parliament passed the Stamp Act, which required a stamp to be placed on all legal documents and many printed materials in the colonies.
In May, news of the new law reached the colonies. There was immediate opposition, including riots in Boston, Massachusetts, Portsmouth, New Hampshire, and Savannah, Georgia.
On June 8, 1765, the Massachusetts Assembly sent a circular letter to the legislatures of the other colonies, inviting them to send delegates to a congress in New York to discuss a unified response to the Stamp Act. The precedent for such a meeting had been set by the Albany Congress in 1754.
Nine of the 13 colonies, including Delaware, chose to send delegates to the meeting, which was held in New York City. McKean was elected as a delegate from Delaware, along with Caesar Rodney.
The Stamp Act Congress convened on October 7, 1765. On October 19, the Stamp Act Congress issued a Declaration of Rights and Grievances. Congress sent petitions to the King and both houses of Parliament and asked for the Stamp Act to be repealed.
McKean argued that each colony should have an equal vote, and votes should not be weighted according to the population. This ensured the voice of small colonies, like Delaware, were heard.
McKean was a member of the committees that drafted the document to the House of Commons, along with Thomas Lynch Sr. and James Otis. He was also a member of the committee that revised the proceedings, along with John Rutledge and Philip Livingston.
McKean signed his name to the official documents of the Stamp Act Congress.
On November 1, 1765, the Stamp Act took effect, but there were no stamp masters available to distribute the stamps. They had resigned or refused to perform their job due to violence and intimidation against them.
On March 18, 1766, Parliament repealed the Stamp Act, primarily due to protest from British merchants who believed it would damage their prospects of doing business in the colonies. However, on that same day, Parliament passed the Declaratory Act, which declared it had the “full power and authority to make laws and statutes of sufficient force and validity to bind the colonies and people of America, subjects of the crown of Great Britain, in all cases whatsoever.”
When McKean and Caesar Rodney returned to Delaware, the Assembly approved of their actions at the Stamp Act Congress with a unanimous vote thanking them for their service.
Ruggles Challenges McKean to a Duel
On the last day of the Stamp Act Congress, some of the delegates were hesitant to sign their names to the documents of the proceedings. One of them was the President of the proceedings, Timothy Ruggles, from Massachusetts.
When Ruggles declined to sign, McKean asked him why he refused. Ruggles said it was “against his conscience.” McKean was outraged, rose to his feet, and shouted “Conscience!” at Ruggles.
Ruggles responded by challenging McKean to a fight, which McKean accepted.
However, Ruggles left New York the next morning and avoided McKean.
