Michigan State Coat of Arms

The Michigan coat of arms appears on official state documents, government buildings, and the state seal. It uses a central shield flanked by two large animals, with a bird perched above and a Latin motto running below. The design has remained essentially unchanged since Michigan adopted it at its first constitutional convention in 1835.

The coat of arms is distinct from the state seal, which is a circular disc used to authenticate government documents. The coat of arms is the heraldic version of the same design — the shield, supporters, crest, and motto together as a formal armorial composition.

Michigan held its first constitutional convention in 1835, two years before Congress formally admitted it to the Union. Delegates at that convention established the state's founding symbols, including the coat of arms and the state motto. Michigan officially became the twenty-sixth state on January 26, 1837.

Lewis Cass, who was governor of Michigan Territory from 1813 to 1831, is credited with shaping the design of the territorial seal that became the foundation for Michigan's coat of arms. Cass selected the frontier scene on the shield and chose symbols intended to reflect Michigan's northern geography and its position on the border of the United States and British Canada.

The word TUEBOR on the shield — Latin for I will defend — was chosen deliberately. Michigan shares a long water border with Canada, and delegates saw the state as a northern gateway into the United States. The motto below the shield, in Latin, was adapted from the inscription on the tomb of the English architect Christopher Wren in St. Paul's Cathedral, London. Where Wren's original line referred to a monument, Michigan's version replaced that word with 'pleasant peninsula.'

The Michigan coat of arms is built around a blue shield supported by an elk and a moose, with a bald eagle above and the state motto on a scroll below. Each element refers to Michigan's geography, its history as a border state, or its natural environment.

The coat of arms connects Michigan's identity to three distinct things: its geography, its wildlife, and its position on the northern border of the United States. The peninsula scene on the shield and the motto below both point directly to Michigan's physical shape — a state surrounded by water on nearly every side.

TUEBOR, placed at the top of the shield, frames Michigan not just as a place but as a border. When the design was adopted in 1835, Michigan shared a long water border with British Canada. The word I will defend signaled that Michigan saw itself as part of the country's northern defense.

The elk and moose on either side are not generic animals. Both lived — and still live — in Michigan's forests. Their inclusion grounds the coat of arms in the specific landscape of the state rather than in abstract symbols.

The Michigan coat of arms grew out of the territorial seal used before Michigan became a state. Michigan Territory was established in 1805, and a territorial seal was created at that time. The design elements that later appeared in the state coat of arms — the frontier scene, the border reference, and the geographical imagery — were already present in the territorial period.

No separately adopted earlier coat of arms with different official standing preceded the 1835 design. What survives from the territorial period are seal impressions and document stamps, not a distinct coat of arms in the heraldic sense.
