REVIVING HUNGARIAN HUSSAR TRADITIONS
In Hungary there are thousands of citizens, who keep the world-famous Hussar traditions alive, which is in fact part of the country’s history since the Hungarian Renaissance of the 16th century. Hussar tradition, thus, is a real “hungaricum”, that Hungary gave the world with great pride. National Gallop organizers believe, that this is a slice of Hungary well-worth to show the world, and it is time to re-think Hungarian traditions in a way that the rest of world would be keen to understand, get to know, and be part of this experience.
