Kagetora Uesugi

Kagetora Uesugi is Ujiyasu's seventh biological son. He entered the Uesugi for a political marriage, and he was allegedly the most favored of Kenshin's adopted sons. After Kenshin's death, he is best known for dying in a civil conflict with his brother, Kagekatsu, in the fight to decide a proper successor.

Samurai Warriors
In Samurai Warriors, he appears in Masamune's version of Odawara to try to punish the boy commander for his interference.

Kagetora appears at Tetorigawa in the third title, where he and Kanetsugu head towards the northwest fortress. His only use in the battle is to gain a tactical bonus of cutting Toshiie's health in half. He joins forces with Katsuyori for the civil war against his brother in Aya's Xtreme Legends Story Mode. During the stage, Kagetora is portrayed as a stern commander who is easily panicked by his brother's supporters. He is grateful for his mother-in-law's aid, yet he is unaware that she sides with him primarily to test her disciple's convictions not due to her faith in him.

Nobunaga's Ambition
Throughout the series, Kagetora has below average stats across the board. He has no outstanding troop proficiencies and is lower than his brother in everything. Kagetora's saving grace is often his high Morality stat, which guarantees his unfailing loyalty to any lord who recruits him. His adoption to Kenshin and his death to Kagekatsu's forces are often included into the series as historical events.

Historical Information
Uesugi Kagetora was Hōjō Ujiyasu's seventh or eighth son. His mother was Tooyama Yasumitsu's daughter whose father originally served the Hōjō and accompanied his grandson to Echigo. His first wife was Hōjō Genan's daughter. His other wives include Seien-In (Nagao Masakage's eldest daughter) and Myōtoku-In (Yasumitsu's younger adoptive sister). Kagetora sired two sons and two daughters, his eldest son being known under the name Dōmanmaru.

Early life
During his childhood, Kagetora was raised at the honorary temple of his great-grandfather, Sōun. Living the distant life of a priest, he was known as Shūsaidō during this time. His other argued childhood names include Shūsaimaru or Sannomaru. According to the Kanhashū Kosenroku, he briefly left his temple dwellings once to serve as a hostage to the Takeda. Other records and common opinion instead note that he was adopted by one of his great-grandfather's brothers, Genan, in 1569. He was married to his adopted father's daughter and gained a closer connection with the Tooyama clan.

Research for Kagetora is muddled at this point with Hōjō Ujihide. Both figures shared a vague background history, resided in Edo, and were both adopted into the Uesugi. During the early Edo period, it was commonly assumed that Ujihide was Kagetora's adult name with the Hōjō. Recent research has drawn doubt on the claim, however, due to no historical records associating Kagetora with the name and the number of conflicting records which distinguishes them as separate individuals. In reality, there are no records which actually calls Kagetora "Hōjō Saburō" either. This name was created by later generations to distinguish Kagetora from Ujihide. While stories claim that it is a homage to his biological father, a definitive origin of the Saburō nickname is also unclear.

What is known for certain was the collapse of relations between the Hōjō and Imagawa in mid-1569. Seeking to expand their territory in the east and oppose their ties with the Takeda, the Hōjō sought a non-aggression pact with the Uesugi called the Etsuso Armistice. The present head of the clan, Hōjō Ujimasa, was ordered to send his son, Kunimasumaru, for adoption to the Uesugi. For one reason or another, Ujimasa had his doubts about sending one of his children and sought to compensate by asking for a hostage. Despite not being a part of the main Hōjō branch, Kagetora was chosen to ease the tension over the alliance. He was promptly designated to be Kenshin's adopted child and sent to the Uesugi in early 1570.

By April the same year, Kagetora was given an audience with Kenshin. He was transferred to Katsugayama Castle within the same year. The Hōjō son was known as Kagetora by this point. His biological ties were disfavored when the Hōjō sought to restore their broken ties with the Takeda soon after. When Ujiyasu perished, Kenshin decided to keep Kagetora as his adopted son rather than send him back to the Hōjō.

Kagetora is popularly romanticized as the only son who Kenshin personally accepted and loved the most. Similar to Kenshin in his youth, Kagetora was known for his physical beauty and was said to have born with his mother's charming features. The lord was said to have related with the youth and his childhood history with the monks pleased him. It is fabled that Kenshin specifically granted his son his own name from his youth (Kagetora) as a show of his favoritism. He was also the first of Kenshin's adopted sons to be accepted as an Uesugi after his adoption, beating his later brother by five years. Kenshin's true thoughts for Kagetora, however, remains unrecorded and unknown.

Family Conflict
Kenshin's health suddenly failed and he died in 1578. His desired successor is an unsolved mystery for modern historians. Since Kagetora conducted the religious rituals for Kenshin's death and the new year ceremonies, many people believe that he was originally designated as heir. Modern documentations of the family even note that Kagetora was the only son at the time who was formally listed under the Uesugi name. Letters and documents of the time period, however, questions the validity of this belief as none of the known writings specifically address Kagetora as clan head. Kagetora's notable absence of military experience also lessens the possibility of his title.

Regardless of whether he was the legitimate heir or not, aggressions between Kagetora and his brother arose mere weeks after their father's passing. Family accomplices who were close to Kenshin in the battlefield mainly sided with Kagekatsu; Kagetora's supporters were external neighbors who came from the south and east, including individuals from the Hōjō, the Daibōji, and Date Terumune. Military conflicts between the brothers are not formally from recorded, but it is believed that the brothers fought several miniature wars throughout Echigo. According to a retainer of the Ashina clan, the brothers were locked in an unmoving stalemate in April.

By May 1578, Kagekatsu assembled approximately 6,000 soldiers to surrounded the outer rim of Katsugayama Castle, seeking to claim Kenshin's family possessions and proof of his inheritance. Kagetora's allies soon surrounded Kagekatsu with an army of 20,000. With various allies keeping Kagekatsu at bay, Kagetora then held himself within Katsugayama Castle with his wife and children and requested the aid of the government offices for the Head of Kantō, Uesugi Norimasa. As such, the noblemen dispute is often dubbed the Otate Revolt by later generations, its namesake being the offices which were constructed for Norimasa and used by Kenshin. The war was largely in Kagetora's favor.

Using the family alliance to his advantage, Kagetora called upon Takeda Katsuyori for aid and his army neared the edges of Echigo in June. To counter Kagetora's movements, Kagekatsu simultaneously repelled Katsuyori's forces at his headquarters, Sakato Castle, while increasing the pressure on Katsugayama Castle. With each passing day, Kagetora's numbers waned and his allies fell to Kagekatsu. Failing to overtake Kagekatsu's defenses, Katsuyori and his retainers called for peace talks between the two brothers. Both sides were in an uneasy stalemate.

Tokugawa Ieyasu's August invasion of Suruga eventually called away Takeda support, and relations between the siblings once again suffered. Kagetora was saved from his brother by the Hōjō reinforcements in September. As it neared winter, however, the unfamiliar snowy conditions and the Kagekatsu's staunch defenses ended the Hōjō's aggressions. Katsugayama Castle's supplies and defenses were becoming barren. During February 1579, his brother's forces then laid siege to the head offices of Kantō to corner Norimasa. Kagekatsu's army drew ever closer to breaking Kagetora's encampment.

Wanting to end the conflict, Norimasa advised the siblings to agree on a treaty. Kagetora was asked to send his eldest son, Dōmanmaru, as a hostage to Kagekatsu. Obliging to the order, Dōmanmaru was sent. According to fables and legends, either Kagekatsu refused the offer or his retainers disagreed with the "pandering". The nine year old boy was either ordered to be executed or was assassinated. When Kagekatsu's troops set fire to the head office, Kagetora, his family, and his few remaining vassals retreated in either February or March 1579.

Planning to flee to Odawara Castle, they rested during their plight at Sameoka Castle and were sheltered by the castle lord, Horie Munechika. Munechika had previously saved his lord with an army of 10,000. After the fire at Kantō, however, his faith in Kagetora dispersed and he soon defected to Kagekatsu. During the violent rebellion within the castle, Kagetora committed suicide with his father-in-law, Tooyama Yasumitsu. He was 26 years old at the time of his death.

Although Kagekatsu emerged as the victor of the family conflict, Kagetora's resistance and his affairs within the east took a sizable chunk of resources from the families who were involved. The Uesugi were particularly drained by the civil dispute.
