Strict flag use regulations: Facts and History of Poland Flag
The national ensign of Poland was adopted 1831 and consists of two equally sized red and white horizontally arranged stripes.
Since 2004, Poland citizens celebrate the Flag’s day on May 2.
Facts and History of Poland Flag indicate that the colours have heraldic origins that come from two main colours of two different nations’ coats of arms: the Polish-Lithuanian Commonwealth.
Because of the fact that there was a communist regime in Poland for many years, in the past years it was forbidden to display a flag without the national coat of arms.
(This was usually done when workers went on strike) However, recent regulations are not that strict anymore: it is allowed to display a national flag as long as it is done in a respectful way.
