Chivalry games were the most popular fun among the nobility. The tracks were built in front of the castles or on the vast, low fields surrounding the settlements. The tournaments would last for several days, and could attract up to 2,000 spectators. The weaponry used in the duels was produced and forged in Serbia during the entire this period, and especially known was the famed Serbian sword or "schiavonesca". The prizes were mostly monetary and were handed over to the winners by the highest lords in the state or the queen consorts themselves. Empress Helena often participated in gatherings and conferences, presiding councils made solely of knights. Princess Milica and her daughter Olivera often headed knightly entourages on their diplomatic missions. Milica's other daughter, princess consort and regent of Zeta Jelena Lazarević, fought against the Venetians and the Ragusans after the death of her husband Đurađ II Balšić in 1403 to 1409, when she handed over the throne to her son Balša III. Apart from waging war, she also provoked the opponents by smuggling salt, a commodity sold only by the Venetians and the Ragusans. In her testament, she left her full knightly armor, expensive vestures and a male, dragon shaped signet ring.
