The Polish Hussars (/həˈzɑːr/, /həˈsɑːr/, or /hʊˈzɑːr/; Polish: Husaria [xuˈsarja]), or Winged Hussars, were one of the main types of Polish cavalry in the Crown of the Kingdom of Poland and in the Polish–Lithuanian Commonwealth between the 16th and 18th centuries. Modeled on the Hungarian Hussars, the early hussars were light cavalry of exiled Serbian warriors; by the second half of the 16th century and after king Stephen Báthory's reforms, hussars transformed into a heavily armored shock cavalry. Until the reforms of the 1770s, the husaria banners were considered the elite of the Polish cavalry.
