Shibata Katsuie, also called Gonroku, was born in Kamiyashiro village, Owari, now located in Meito-Ku, Nagoya City. Initially, he pledged allegiance to Oda Nobunaga's younger brother, Oda Nobukatsu, and participated in Nobukatsu's scheme to usurp his elder brother's power. Katsuie led the charge against Nobunaga in the Battle of Ino in 1556 but was defeated. While Nobunaga had his younger brother executed, Katsuie was spared. Despite their past conflict, Katsuie became one of Nobunaga's commanders, earning a reputation for bravery and loyalty.
Katsuie's military career was marked by notable victories, such as his escape from the besieged Chokoji Castle during the Battle of Anegawa in 1570, where he demonstrated exceptional leadership by destroying the remaining water urns to prevent retreat. After this, he was tasked with establishing himself in Echizen Province (modern-day Fukui Prefecture) and constructed Kitanosho Castle, boasting a nine-story keep, the largest in Japan at the time.
Following Nobunaga's assassination at Honnoji in Kyoto, Katsuie engaged in battles with Uesugi Kenshin's forces and participated in the siege of Matsukura. His involvement prevented him from joining the pursuit of Akechi Mitsuhide, Nobunaga's killer.
During the Battle of Shizugatake, Katsuie supported Oda Nobutaka, Nobunaga's third son, as heir against Hideyoshi's preferred successor, Samboshi. Snowed in and facing Hideyoshi's advancing armies, Katsuie retreated to Kitanosho Castle. In the face of imminent defeat and encircled by Hideyoshi's troops, Katsuie commanded his daughters and wife, Oichi (interestingly, Nobunaga's sister), to seek refuge under Hideyoshi's protection.However, Oichi refused, and in a tragic end, Katsuie and Oichi committed seppuku together, with Katsuie initiating a fire that consumed Kitanosho Castle along with their bodies.
