State Seal of Massachusetts

Massachusetts's state seal shows a Wampanoag figure on a blue shield, an armored arm holding a sword above, and the motto "Ense petit placidam sub libertate quietem" ("By the sword we seek peace, but peace only under liberty"), a phrase attributed to Algernon Sidney and first incorporated by Paul Revere in 1775. This profile appears in the list of U.S. state seals.

Massachusetts State Seal History and Origin

Paul Revere designed the first Massachusetts seal in 1775 for the Massachusetts Provincial Congress, before independence was declared. The design incorporated a Wampanoag figure with a downward bow, a five-pointed star, a sword-bearing arm, and the motto "Ense petit placidam sub libertate quietem," a phrase attributed to Algernon Sidney, who was executed in 1683 for opposing absolute royal power.

When Massachusetts adopted its constitution in 1780, the oldest functioning written state constitution in continuous use in the United States, the seal was formally incorporated as the official emblem of the Commonwealth. Massachusetts styled itself a Commonwealth rather than a state, a distinction preserved in the border inscription "Sigillum Reipublicae Massachusettensis."

In 2024, Massachusetts established the Massachusetts Seal, Flag, and Motto Advisory Commission to develop recommendations for possible new state symbols. That process reopened debate over the seal's imagery, but it did not itself replace the traditional seal.

Meaning

Great Seal of Massachusetts Meaning

The Great Seal of the Commonwealth of Massachusetts centers on a Wampanoag figure with a downward bow on a blue shield, paired with the motto "Ense petit placidam sub libertate quietem." Paul Revere first designed the seal in 1775; the motto is attributed to Algernon Sidney, an English theorist executed in 1683, and translates as "By the sword we seek peace, but peace only under liberty." The traditional composition remains the official seal while the Massachusetts Seal, Flag, and Motto Advisory Commission continues work on possible future replacements.

What the Massachusetts State Seal Symbols Mean

The traditional Great Seal of Massachusetts packed four distinct symbol systems into a single heraldic design.

Wampanoag Figure

Wampanoag Figure

The central figure on the traditional seal is a Native American holding a bow in his right hand and an arrow in his left, with the bow pointing downward. The figure represents the indigenous Wampanoag people of southeastern Massachusetts, whose territory included the land where Plymouth Colony was established in 1620.

Armored Arm with Sword

Armored Arm with Sword

Above the shield, a right-side arm in a knight's armor holds a broadsword upright. This element appeared in the colonial arms of Massachusetts and was retained in the 1775 Revere design. It illustrates the motto directly: the sword is drawn not to conquer but to defend liberty.

Motto — Ense petit placidam sub libertate quietem

Motto — Ense petit placidam sub libertate quietem

"Ense petit placidam sub libertate quietem" is Latin for "By the sword we seek peace, but peace only under liberty." The line is attributed to Algernon Sidney, an English republican theorist beheaded in 1683. Paul Revere incorporated it into the 1775 seal as a statement of Revolutionary purpose.

Star

Star

A five-pointed star appears in the upper right of the blue shield. It marks Massachusetts as one of the original thirteen states. Massachusetts ratified the U.S. Constitution on February 6, 1788, as the sixth state.

Border Inscription

Border Inscription

"Sigillum Reipublicae Massachusettensis" circles the outer border, translating as "Seal of the Commonwealth of Massachusetts." The Latin "Reipublicae" reflects the name Massachusetts gave itself in its 1780 constitution, choosing "Commonwealth" over the simpler "State" used by most other states.

Previous Versions of the Massachusetts State Seal

The Massachusetts seal has two main historical phases in official use: the Revolutionary-era provincial seal designed by Paul Revere in 1775, and the Commonwealth seal formally adopted in 1780. Later changes affected rendering and proportions, but not the core composition.
