In 2006, the National Bank of Poland launched the issue of the "History of Polish Riding" series, the aim of which was to present Polish military formations and types of armaments over the centuries. So far, five coins have been issued in the "History of Polish Riding" series: in 2006: The Piast Rider in 2007: Heavy-armed knight of the XV century in 2009: Hussar of the 17th century in 2010: Chevalier of the Emperor Napoleon I Guard in 2011: Ulan of the Second Republic of Poland The obverse presents the image of the eagle established as the emblem of the Republic of Poland, against the background of a stylized hussar wing. Below there is a stylized image of elements of the hussar gutter: a pennant, a conchik and a mace. On the reverse side there is a stylized image of a 17th century hussar, on a horse, in armour, with hussar wings and leather leopard on his back, holding a copy with a pennant.  The beginnings of Polish hussars date back to the turn of the fifteenth and sixteenth centuries. The first hussars were Serbs and Hungarians who came to Poland to fight the Turks. They served for money as a heavy ride; their first successes were already in 1506 near Kleck, breaking up considerable Tatar forces. The Hussars were distinguished from any ride by their wings, which at the turn of the 16th and 17th centuries became their hallmark. The Hussars were an exceptional phenomenon - this is how they were perceived both at the time of their magnificence and later, when their legend served to strengthen their hearts, reminding them of the glory of Polish armour.
