The 1573 was the last stand of the Azai clan, one of Oda Nobunaga's chief opponents. Nobunaga took Odani Castle from Azai Nagamasa, who, left with no other option, committed suicide along with his son. His wife and three daughters were entrusted to Nobunaga, considering they were his sister and nieces. Two of Nagamasa's daughters would later marry into powerful families. Their escape from the besieged castle became a fairly common sentimental scene in traditional Japanese art.
