Happy Semiquincentennial, America!

As we count down to The Fourth of July 2026, The History Center of San Luis Obispo County wants to celebrate the 250th Birthday of The United States of America with periodic looks at what was happening 250 years ago today:

On June 19, 1776, the Second Continental Congress passed the following resolution to provide uniforms to the Continental Army:

Resolved, That it be recommended to the assemblies and conventions of the United Colonies, forthwith to cause a suit of clothes, of which the waistcoat and breeches may be made of deer leather, if to be had on reasonable terms, a blanket, felt hat, two shirts, two pair of hose, and two pair of shoes, to be manufactured, or otherwise procured at reasonable rates, in their respective colonies, for each soldier of the American Army, enlisted therein for the present campaign, and that the same be baled, invoiced, and stored in suitable places, to be delivered to the order of Congress, or the commander in chief of the American Army….and that the cost thereof be deducted from the pay of the soldiers who shall receive the same.

And that’s the way it was 250 years ago today.

On June 18, 1776, delegates from across Pennsylvania gathered at Carpenters’ Hall in Philadelphia for the first meeting of the Pennsylvania Provincial Conference. Pennsylvania was initially hesitant to support independence due to its Quaker population and its deep-rooted pacifist traditions, an influential and wealthy merchant class who feared economic ruin, and a very conservative colonial assembly. Conversely, on June 18th, 97 delegates attended the conference, determined to break from British rule. The Conference declared Pennsylvania independent from the British Empire, organized militia support for the Revolutionary War, and planned elections for a constitutional convention. Delegates also approved resolutions declaring the existing colonial government inadequate to meet the crisis facing the colonies. Pennsylvania had been the final holdout among the Thirteen Colonies, and the Conference’s actions helped clear the way for American independence afterward.

And that’s the way it was 250 years ago today.

On June 17, 1776, the Second Continental Congress debated creation of a permanent union among the thirteen colonies. At the time, many colonies increasingly viewed themselves as separate sovereign states rather than dependent British territories. Delegates unanimously agreed that a formal confederation was necessary to coordinate the growing independence movement and the war against Great Britain. Congress appointed a committee with one representative from each colony to draft the Articles of Confederation and Perpetual Union. Lawmakers understood the task would be difficult and time-consuming because each colony guarded its authority carefully. The Articles finally took effect in 1777, strengthening the war effort and helping secure foreign recognition and alliances abroad.

And that’s the way it was 250 years ago today.

June 16, 1776, marks the day after New Jersey’s Provincial Congress declared former Royal Governor William Franklin “an enemy to the liberties of this country.” The Loyalist son of Benjamin Franklin had remained under house arrest since January after refusing to support independence. He had been not only New Jersey’s last royal governor, but also the last in the colonies still trying to cling to British Royal Authority. Earlier, Benjamin Franklin had visited his son at the governor’s mansion, hoping unsuccessfully to persuade him to join the revolutionary cause. William instead stayed loyal to Britain, was removed from office, convicted of treason, and later imprisoned in Connecticut. His loyalty cost him dearly. He never reconciled with his father, lost his wife during the war, and eventually fled to England, where he died in 1813 in bitter exile.

And that’s the way it was 250 years ago today.

On June 15, 1776, delegates from Delaware’s Three Lower Counties gathered in New Castle and voted to break from both the British Crown and Pennsylvania’s proprietary government. The assembly rejected King George III and established an autonomous government called The Delaware State. The entity adopted its own constitution and its first governors went by the title of “President”. This date later became known as Separation Day, marking Delaware’s historic step toward self-rule. Yet not all residents celebrated the occasion without criticism. A small movement called the Unificationists, descendants from early Quaker, Swedish, and Finnish settlers, argued that Separation Day exaggerates Delaware’s importance and independence. Though often humorous in tone, their criticism reflects lingering debates about Delaware’s split from Pennsylvania during the colonial revolutionary era.

And that’s the way it was 250 years ago today.

On June 12, 1776, Virginia delegates unanimously adopted the Virginia Declaration of Rights at the colonial capitol of Williamsburg. Principal author George Mason drafted the document to proclaim that all men possessed inherent rights, including liberty, property, and the ability to reform or abolish inadequate government. Influenced by English political traditions and the writings of John Locke, the declaration rejected hereditary privilege and described government as the servant of the people. Debate continued over religious freedom and other provisions before the final version passed. The declaration later inspired both the Declaration of Independence and the United States Bill of Rights, establishing an enduring foundation for American constitutional principles and individual freedoms nationwide.

And that’s the way it was 250 years ago today.

On June 11, 1776, the Second Continental Congress appointed the Committee of Five to draft a declaration explaining why the American colonies sought independence from Great Britain. The committee included Thomas Jefferson, John Adams, Benjamin Franklin, Roger Sherman, and Robert Livingston. Delegates selected Jefferson to write the first draft at his rented Philadelphia quarters, while Adams and Franklin carefully reviewed and revised his work. The committee aimed to justify separation, unite the colonies, and encourage foreign alliances against Britain. Their completed document reached Congress on June 28. After further debate and revisions following the passage of the Lee Resolution on July 2nd, Congress officially adopted the Declaration of Independence on July 4, 1776.

And that’s the way it was 250 years ago today.

On June 10, 1776, the Second Continental Congress delayed a final vote on Richard Henry Lee’s resolution for independence until July 1. Delegates debated the bold proposal declaring the colonies free and independent from British rule, but many moderates wanted additional support before committing to separation. Some representatives also needed to return home to attain approval from their colonial governments before proceeding. To avoid losing valuable time, Congress would appoint a committee to draft a formal declaration explaining why the colonies sought independence from Great Britain. The postponement allowed leaders to strengthen unity among the colonies while preparing the historic statement that later became the Declaration of Independence.

And that’s the way it was 250 years ago today.

On June 9, 1776, General George Washington remained in New York City, racing to strengthen defenses as British invasion forces gathered nearby. Facing severe shortages of men, weapons, and supplies, Washington informed General Philip Schuyler that no additional troops could be spared for Fort Ticonderoga. He urged commanders to fortify northern communication posts against attack. Across Manhattan, Continental soldiers tore up streets for barricades, cut timber for defenses, and positioned cannon overlooking the harbor. Reports from Major General Artemas Ward written that day warned that British transports carrying thousands of Scottish troops were sailing toward Boston. Three months later, despite these desperate preparations, the British captured Manhattan after fierce fighting. General Washington lost about 2/3 of the major battles in which he engaged.

And that’s the way it was 250 years ago today.
