MEDIEVAL POLISH ANTHEM "GAUDE MATER POLONIA" (LYRICS)
Gaude Mater Polonia "Rejoice, Mother Poland" was the most popular medieval Polish anthem, written in the 13th–14th century in memory of Saint Stanisław Szczepanowski, Bishop of Kraków. Polish knights used to sing it after victory in battle.
The anthem came to existence in 1253, along with the canonisation of Stanisław Szczepanowski on 8 September in Assisi and was officially used until the partitions of Poland-Lithuania in 1795. The flag represents the Commonwealth of Poland and Lithuania (1569 - 1795).
