Hemp in Early American Flags
Separating documented hemp history from popular flag mythology in Revolutionary America.
The 'hemp flag' claim is pure folklore—no evidence supports it. Early American flags were made from wool bunting, not hemp. But this myth actually overshadows hemp's real importance to early America: it was critical for rope, sailcloth, and paper. Washington and Jefferson grew it as a fiber crop, not for smoking. The myth spread through 1980s–90s cannabis advocacy literature without historical foundation.
The Claim and Its Origins
A persistent claim in cannabis advocacy holds that the first American flag—often specifically the Betsy Ross flag of 1776—was sewn from hemp fabric. This assertion typically circulates alongside related claims 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 rest on a kernel of historical fact: Washington and Jefferson did cultivate hemp at Mount Vernon and Monticello respectively. Strong evidence[1][2] However, other elements are demonstrably false. The engrossed Declaration of Independence is written on parchment—animal skin prepared for writing—not hemp paper. Strong evidence[3] The flag claim occupies murkier ground, lacking direct supporting documentation yet remaining widely repeated.
What the Historical Record Says About the Flag
The Flag Resolution adopted by the Second Continental Congress on June 14, 1777, specifies only colors and arrangement: "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." Strong evidence[4] No detail regarding fiber, weave, or manufacturer appears in the resolution.
The Betsy Ross attribution itself rests entirely on family oral tradition. The story was not made public until 1870, when Ross's grandson William Canby presented it to the Historical Society of Pennsylvania—nearly a century after the flag's purported creation. Disputed[5] Most modern flag historians, including those at the Smithsonian Institution, regard the Ross attribution as unverified and likely legendary. No flag authenticated as Ross's work from 1776 survives for examination.
Without an authenticated original artifact, any claim about fiber composition—hemp, linen, wool, or cotton—cannot be verified through material analysis. Such claims remain pure speculation.
What 18th-Century Military Flags Were Actually Made From
Military and naval flags throughout the late 18th century were standardly manufactured from wool bunting, a loosely woven worsted wool textile prized for its ability to hold dye and fly well in light winds. British Royal Navy ensigns of the period were formally standardized in wool bunting, and American naval practice adopted the same convention. Strong evidence[6]
Hemp, by contrast, served as the dominant fiber for cordage, sailcloth, and rigging on vessels of the era—uses requiring strength and durability in demanding conditions. Strong evidence[7] The U.S. Navy and merchant marine consumed vast quantities of hemp for rope and canvas, which partly explains why colonial and early federal governments actively encouraged hemp cultivation through legal mandates. Strong evidence[8]
While hemp can technically be woven into cloth of varying weights and could theoretically have been used for flags, no documentary evidence or surviving artifacts indicate this practice. Linen (from flax) and cotton also saw use in smaller domestic or ceremonial flags. Hemp fabric for flags was not the standard textile choice of the era.
Hemp's Genuine Historical Importance to Early America
The folklore surrounding hemp flags actually obscures hemp's substantial and well-documented role in early American economic and military life:
- Colonial mandates: Virginia passed laws in the 17th century requiring farmers to grow hemp as a cash crop. Strong evidence[8]
- Founding-era cultivation: George Washington documented hemp cultivation at Mount Vernon in his farm records and diaries, explicitly noting its fiber and rope applications. Strong evidence[1]
- Monticello production: Thomas Jefferson grew hemp at Monticello and designed a hemp brake—a mechanical processing device—for breaking the fiber from the woody core. Strong evidence[2]
- Military supply: The U.S. Navy remained a major consumer of hemp rope and sailcloth well into the mid-19th century, making hemp production strategically important. Strong evidence[7]
Critically, the hemp grown in early America was a fiber and seed crop, selected for tall stalks and strong fiber, not for resin or psychoactive properties. No credible evidence supports the claim that Washington, Jefferson, or other Founders cultivated cannabis for intoxication.
How the Myth Developed and Spread
The "hemp flag" claim appears to have gained currency during the cannabis legalization movement of the 1970s and 1980s. Jack Herer's influential The Emperor Wears No Clothes (first published 1985) compiled an ambitious case for hemp's historical importance and is widely credited with revitalizing modern hemp advocacy. Anecdote[9]
However, Herer's work mixed well-documented historical facts—such as Washington's and Jefferson's hemp cultivation, and the Navy's reliance on hemp cordage—with claims presented without primary sources. The flag assertion appears in advocacy literature of this period consistently lacking any direct historical documentation or footnote.
From cannabis legalization pamphlets and early internet forums, the claim migrated into social media memes, often paired with the false declaration-paper claim. Repetition across multiple platforms created an impression of established historical fact among readers unfamiliar with primary sources. This is a textbook example of how unsourced claims can spread within a movement and eventually achieve the appearance of legitimacy through sheer volume of repetition. Anecdote
Summary and What to Cite Instead
Was the first American flag possibly made from hemp cloth? Plausibly yes in the abstract—hemp was an available textile fiber in 1776—but no documentation exists for such use. No data
Was the Betsy Ross flag (or any authenticated original) made of hemp? Unknown and unknowable. No authenticated flag from 1776 survives for material analysis. No data
Were most 18th-century military and naval flags made of hemp? No. Wool bunting was the standard. Strong evidence
Was hemp genuinely important to early America? Yes, overwhelmingly as a source of rope, sailcloth, paper, and cordage—critical to naval power and merchant shipping. Strong evidence
If you wish to emphasize hemp's role in American history, cite Washington's farm records, Virginia's colonial hemp laws, or Navy supply contracts. These sources are solid, verifiable, and require no embellishment. The real history stands on its own.
