The coat of arms of Alabama depicts a shield upon which is carried the symbols of the five states which have at various times held sovereignty over a part or the whole of what is now Alabama. These are the ancient coat of arms of France, the ancient coat of arms of Crown of Castile for Spain, the modern Union Jack of the United Kingdom and the battle flag of the Confederate States. On an escutcheon of pretence is borne the shield of the United States. The crest of the coat represents a ship which brought the French colonists who established the first permanent European settlements in the territory. Below is the state motto: Audemus jura nostra defendere, meaning "We dare defend our rights."

Historical coats of arms of the U.S. states date back to the admission of the first states to the Union. Despite the widely accepted practice of determining early statehood from the date of ratification of the United States Constitution, many of the original colonies referred to themselves as states shortly after the Declaration of Independence was signed on 4 July 1776. Committees of political leaders and intellectuals were established by state legislatures to research and propose a seal and coat of arms. Many of these members were signers of the Articles of Confederation, Declaration of Independence, and United States Constitution. Several of the earliest adopted state coats of arms and seals were similar or identical to their colonial counterparts.
