Oda Nobukatsu, a Daimyo and esteemed warrior, was born as the second son of Oda Nobunaga in Ko’ori Castle, situated in Niwa-Gun, presently known as Konan City of Aichi Prefecture, in the year 1558.
In 1570, following a brief conflict between the Oda and the Kitabatake clan of Ise Province (Mie Prefecture), Nobukatsu was adopted as the heir of the Kitabatake clan to restore peace. He married the daughter of Kitabatake Tomonori, but soon after the wedding, he orchestrated a series of ruthless actions. This included the murder of his father-in-law, the elimination of several key Kitabatake supporters, the imprisonment of the former Lord of Ise, and the complete usurpation of control for himself. Subsequently, Nobukatsu launched an unsuccessful invasion of neighboring Iga Province (also in Mie Prefecture). In response to his failure, Nobukatsu faced the wrath of his father, Nobunaga, and to preserve his authority, he was compelled to annihilate the entire region, including Iga and the remaining Kitabatake clan, along with their prestigious residences and Kiriyama Castle.
The 1582 coup known as the Honno-ji Incident resulted in the deaths of Nobukatsu's father and elder brother, Nobutada, sparking a dispute over succession between the two surviving brothers. Despite being born 20 days prior to Nobukatsu, Nobutaka, whose mother was a concubine, was considered younger due to Nobukatsu's noble-born mother. The brothers contended for their father’s legacy until the Kiyosu Kaigi, a meeting held at Kiyosu Castle, where Toyotomi Hideyoshi and other chief retainers of Nobunaga decided to nominate Nobutada’s infant son, Samboshi (later Oda Hidenobu), as the rightful heir.
Subsequently, Nobukatsu reclaimed his Oda lineage, relinquishing the Kitabatake name, and was appointed Lord of Mino (Gifu), Owari (Aichi), and Ise (Mie) provinces. Fearing his brother Nobutaka's growing influence, Nobukatsu allied with Toyotomi Hideyoshi to eliminate him, leading to Nobutaka's forced seppuku in mid-late June 1583. However, Nobukatsu later clashed with Hideyoshi over authority, prompting him to seek support from Tokugawa Ieyasu to overthrow Hideyoshi, culminating in the Battle of Komaki Nagakute in 1584. Despite initial hostilities, Nobukatsu eventually accepted Hideyoshi's peace offering, aligning himself with Hideyoshi and relinquishing his allegiance to Ieyasu.
Nobukatsu remained loyal to Hideyoshi, serving at the Siege of Odawara in 1590. However, he refused to surrender his domains when Hideyoshi redistributed his retainers' holdings, resulting in his forced retirement as a monk. Despite this, he was later pardoned and granted lands. Following Hideyoshi's death, Nobukatsu was entrusted with the guardianship of Hideyoshi’s infant son and heir, Hideyori, at Osaka Castle. However, in 1614, he betrayed the Toyotomi clan, surrendering to Tokugawa Ieyasu during the Winter Siege of Osaka. As a reward for his betrayal, he was granted the Uda-Matsuyama Domain in Yamato Province (Nara Prefecture), where he resided until his demise in 1630.
