The 1777 coat of arms on the Delaware flag consists of a soldier and a farmer supporting a shield with a wheatsheaf, an ear of corn and an ox representing Delaware’s agricultural foundation. A ship in full sail symbolizes Delaware’s status as a maritime state; the blue and buff correspond to the colors of the Revolutionary War uniform. The diamond was added after the flag was adopted in July 1913. The date on the bottom of the blue field symbolizes that Delaware was the first state to ratify the U.S. Constitution.
