Hemp in Early American Flags

The Claim

A common talking point in cannabis advocacy holds that the first American flag — often specifically the Betsy Ross flag of 1776 — was sewn from hemp fabric. The claim circulates alongside related assertions that the Declaration of Independence was written on hemp paper and that George Washington and Thomas Jefferson grew cannabis for its psychoactive properties. Anecdote

Some of these claims have a kernel of truth (Washington and Jefferson did grow hemp as an agricultural fiber crop Strong evidence), and some are flatly wrong (the engrossed Declaration is on parchment — animal skin — not hemp paper Strong evidence ^[1]). The flag claim sits in a murkier middle ground.

What the Historical Record Actually Says

The Flag Resolution passed by the Second Continental Congress on June 14, 1777 reads in full: 'Resolved, That the flag of the thirteen United States be thirteen stripes, alternate red and white; that the union be thirteen stars, white in a blue field, representing a new constellation.' ^[2] It specifies colors and arrangement. It says nothing about fiber, weave, or manufacturer.

The Betsy Ross story itself — that Ross sewed the first flag in 1776 at the request of George Washington — was not publicly told until 1870, when her grandson William Canby presented it to the Historical Society of Pennsylvania based on family oral tradition. Disputed ^[3] Most modern flag historians regard the Ross attribution as unverified. No flag authenticated as Ross's work from 1776 survives.

Because no authenticated 'first flag' exists for laboratory fiber analysis, any claim about what it was made of — hemp, linen, wool, or cotton — is inference, not evidence.

What 18th-Century Flags Were Generally Made Of

Military and naval flags of the late 18th century were most commonly made from wool bunting, a loosely woven worsted wool fabric that held dye well and flew in light winds. British Royal Navy ensigns of the period were standardized in wool bunting, and American naval practice followed the same convention. Strong evidence ^[4]

Hemp, by contrast, was the dominant fiber for cordage, sailcloth, and rigging on ships of the era — not typically for signal flags. Strong evidence ^[5] The U.S. Navy and merchant marine consumed enormous quantities of hemp for rope and canvas, which is one historical reason hemp cultivation was actively encouraged by colonial and early federal governments. ^[6]

Linen (from flax) and cotton were also used for smaller domestic or ceremonial flags. Hemp fabric for flags is not impossible — hemp can be woven into cloth of varying weights — but it was not the standard flag textile.

Hemp's Real Role in the Early Republic

The folklore overstates a flag connection that probably isn't there, while underselling hemp's genuine importance to early America, which was substantial.

• Virginia passed laws in the 17th century requiring farmers to grow hemp. Strong evidence ^[6]
• George Washington recorded hemp cultivation at Mount Vernon in his diaries, primarily for fiber and rope. Strong evidence ^[7]
• Thomas Jefferson grew hemp at Monticello and designed a hemp brake (a processing tool). Strong evidence ^[8]
• The U.S. Navy was a major consumer of hemp rope and sailcloth into the mid-19th century. Strong evidence ^[5]

None of this evidence speaks to flag manufacture, and none of it supports the idea that the Founders grew hemp for smoking. The cannabis grown in early America was a fiber/seed crop selected for tall stalks, not resin production.

How the Myth Spread

The 'hemp flag' claim appears to have gained traction in 1970s–1990s cannabis legalization literature, most influentially Jack Herer's The Emperor Wears No Clothes (first published 1985). ^[9] Herer's book compiled a sweeping case for hemp's historical importance and is credited with energizing the modern hemp movement, but it also mixed well-documented facts with overstated or unsourced claims. The flag assertion is usually presented without a primary source.

From there it spread through pamphlets, early internet forums, and eventually social media memes, often paired with the (false) claim about the Declaration being written on hemp paper. The repetition created an illusion of established fact. Anecdote

This is a textbook case of how cannabis advocacy can undermine itself: the real history of American hemp is genuinely interesting and well-documented, and doesn't need embellishment.

Bottom Line

• Were any early American flags possibly made from hemp cloth? Plausibly yes, given hemp's availability as a textile fiber — but undocumented. No data
• Was 'the first flag' (Betsy Ross or otherwise) made of hemp? Unknown and unverifiable. No authenticated original survives. No data
• Were most 18th-century military/naval flags made of hemp? No. Wool bunting was standard. Strong evidence
• Was hemp important to early America? Yes, overwhelmingly for rope, sailcloth, and paper — not flags. Strong evidence

If you want to cite hemp's role in American history, cite Washington's diaries, Virginia's hemp laws, or the Navy's cordage contracts. Skip the flag.
