"Poland Is Not Yet Lost", also known as the "Dąbrowski Mazurka", and the "Song of the Polish Legions in Italy", is the national anthem of Poland. The original lyrics were written by Józef Wybicki in Reggio Emilia, in Northern Italy, between 16 and 19 July 1797, two years after the Third Partition of Poland erased the Polish–Lithuanian Commonwealth from the map. Its initial purpose was to raise the morale of Jan Henryk Dąbrowski's Polish Legions that served with Napoleon Bonaparte in the Italian campaigns of the French Revolutionary Wars. "Mazurek Dąbrowskiego" expressed the idea that the nation of Poland, despite lacking an independent state of their own, had not disappeared as long as the Polish people endured and fought in its name.
