The colors, which are of heraldic origin and have a history dating back to 1831, are one of the three constitutional symbols of the Republic of Poland, along with the coat of arms, the White Eagle, and the national anthem, Mazurek Dabrowskiego.
The Polish flag is a rectangular piece of cloth in the national colors, with or without the Polish coat of arms on the white stripe. The Polish Flag Day is celebrated on 2nd May.
The emblem of Poland consists of a white eagle on a red field. Its current appearance consists of a turned towards the right, single-headed, crowned eagle with golden claws and beak, upon the red shield. The heraldic description of the national emblem is a silver eagle with the golden crown pictured on a red field.
According to legend, the White Eagle emblem originated when Lech, Poland’s legendary founder, once saw a white eagle against the setting sun which appeared tipped with gold. He was so delighted with the view that he decided to settle nearby and chose an eagle as his emblem.
Since 1927 the Polish national anthem is the 'Dabrowski's Mazurka'. Originally called the "Anthem of the Polish Legions in Italy", from its initial verse, "Jeszcze Polska nie zginela" it is also informally known in English as "Poland Is Not Yet Lost" or "Poland Has Not Yet Perished". The words were written by Józef Wybicki in 1797.
The song originated during the formation of the Polish Legions in Italy in the 18th century. Józef Wybicki, a poet and an officer in the Legions, wrote it in Reggio Emilia in July 1797 to the tune of a mazurka.
Beginning with the words, "Poland has not yet perished," it was a patriotic call to arms to save the Polish state which had fallen under foreign rule. It quickly became very popular with the Polish Legionnaires and eventually, after Poland regained independence in 1918, was declared the national anthem.
