This article is about the present collection of coats of arms of the United States. For an overview of those presented in the historical works State Arms of the Union (1876) and Series 1882BB National Bank Notes, see Historical armorial of U.S. states from 1876.
The coats of arms of the U.S. states are coats of arms, that are an official symbol of the state, alongside their seal. Eighteen states have officially adopted coats of arms. The former independent Republic of Texas and Kingdom of Hawaii each had a separate national coat of arms, which are no longer used.
Heraldicarms were worn (embroidered) on a coat which knights wore over their armor, hence coat of arms,[1] a term which dates back roughly 1,000 years[2] to joustingtournaments.[3] A state coat of arms may exist independently of the seal, but the reverse is not generally the case.[4] A seal contains a coat of arms or other devices[5][6] whereas a state coat of arms constitutes the bulk of a seal,[6][7] except for the wording identifying it as the "Great Seal of the State of..."[8] A "seal" has been described as the design impressed on public or legislative official documents,[9] whereas a coat of arms generally appears for illustrative purposes. Examples include flags and banners,[10] and state militia uniform caps[11] and buttons,[12] as well as specifically-designed regimental coats of arms for U.S. Infantry Regiments, and National Guard units.[13]
A coat of arms of a nation or state is usually the design or device of the obverse of its seal. It is an official emblem, mark of identification, and symbol of the authority of the government of a nation or state. A nation or state's coat of arms is oftentimes referred to as the national or state arms.
