Adopted in 1919. The flag of Poland has two equal horizontal bands of white (top) and red. Colors derive from the Polish emblem, a white eagle on a red field. (ref: CIA World Factbook) The Poland national flag also appears with the coat of arms (white eagle on a red shield) displayed in the center of the top white band. This flag is typically used as the state diplomatic flag overseas, the naval and merchant ensign, and the civil air ensign. It is also often unofficially displayed within the United States by citizens of Polish heritage.
