The coat of arms of Antioquia, in its current form, dates back to August 23, 1812 when it was officially adopted by the Chamber of the Senate of Antioquia by means of Decree 21 of 1812, replacing the Great State Seal of Antioquia that was sanctioned by State President José María Montoya Duque on September 2, 1811. Following the incorporation of Antioquia to the United Provinces of New Granada and subsequently to the Granadine Confederation and the United States of Colombia, the Sovereign State of Antioquia adopted the coat of arms of Colombia as its state arms. Antioquia reverted to the original coat of arms in 1912 for the occasion of the centenary of the independence of Antioquia and it has been in official use ever since.
