Uesugi Kenshin stands out as one of the most formidable daimyo of the Sengoku period, presenting the sole substantial challenge to Oda Nobunaga's quest for dominance.
Born Nagao Kagetora, the fourth son of Nagao Tamekage, Kenshin's ascent to power began after his father's demise, amidst a struggle among his brothers. Placed in a temple at age seven, Kenshin's emergence as a leader was urged by his father's loyal retainers at age 14, due to dissatisfaction with his brother's governance. Reluctantly taking up the mantle, Kenshin swiftly established himself as a capable ruler, consolidating the territories inherited from his father.
Dubbed the "Dragon of Echigo" (now Niigata Prefecture), Kenshin is renowned for his enduring rivalry with the neighboring Daimyo, Takeda Shingen. Their clashes at Kawanakajima, spanning five engagements, culminated in the intense Battle of Kawanakajima, where Kenshin personally confronted Shingen in a legendary exchange of blows.
Despite Kenshin's military prowess and honorable conduct, characterized by his respectful treatment of adversaries, he was also known for his heavy drinking. In 1577, having claimed victory over Oda forces at the Battle of Tedorigawa, Kenshin was poised to continue his campaign against Nobunaga when he suffered a sudden seizure and passed away four days later.
While some accounts suggest assassination by a ninja, evidenced by Kenshin's composed death poem, most historians attribute his demise at age 49 to excessive drinking and potential stomach or esophageal cancer. His poignant death poem reflects on life's fleeting nature: "Forty-nine years have passed like a dream in the night. The Glories of Life disappear like a cup of sake."

After his father's death in 1481, Norikage entered the service of his brother, Asakura Ujikage.
