Японский клан Датэ: История и влияние

Japanese noble family

The Date clan (伊達氏) is a Japanese samurai kin group.

The Date family was founded in the early Kamakura period (1185–1333) by Isa Tomomune who originally came from the Isa district of Hitachi Province (now Ibaraki Prefecture), and was a descendant of Fujiwara no Uona (721–783) in the sixteenth generation. The family took its name from the Date district (now Date City in Fukushima Prefecture) of Mutsu Province which had been awarded in 1189 to Isa Tomomune by Minamoto no Yoritomo, the first Kamakura shōgun, for his assistance in the Genpei War and in Minamoto no Yoritomo's struggle for power with his brother, Minamoto no Yoshitsune. During the Nanboku chō Wars in the 1330s, the Date supported the Imperial Southern Court of Emperor Go Daigo through Kitabatake Akiie, who had been appointed Commander in Chief (or Chinjufu Shōgun) of the Defense of the North, by the emperor. As warlords gained and lost power in the Sengoku period, trying to unite the country, the Date, along with a handful of other powerful families, did all they could to retain independence and dominance over their section of the land (in the case of the Date, the far north). Though not gaining the fame or power of the likes of Oda Nobunaga, Uesugi Kenshin, or Toyotomi Hideyoshi, they resisted the invasions of these warlords into the north. Date Masamune (1567–1636) contributed in particular to this effort, consolidating the families of the north into alliances against the major warlords. In 1589, Masamune with the help of former Ashina's samurai, Inawashiro Morikuni, seized the Aizu Domain of the Ashina at the Battle of Suriagehara; and he installed himself at Kurokawa Castle in Wakamatsu Province. However, the following year, Hideyoshi triumphed over the Hōjo of Odawara; and Hideyoshi then obliged Masamune to be content with the fief of Yonezawa (300,000 koku). in contrast with the fudai or insider daimyō clans which were hereditary vassals or allies of the Tokugawa clan. In 1600, Ieyasu charged the Date to fight against Uesugi Kagekatsu; and, with the assistance of Mogami Yoshiteru, Masamune's forces defeated Naoe Kanetsugu. In recognition of this success in battle, Masamune was granted the fiefs in twelve districts which had been held until that time by the Uesugi clan. The Date established themselves at Sendai (620,000 koku). By 1658, Masamune changed the name of the Uesugi's castle at Iwatezawa to Sendai Castle. Succession disputes erupted; there were a number of direct descendants of Masamune, and many kinsmen and hereditary vassals of the Date who resided nearby held estates of at least 10,000 koku, and thus had some influence. In 1660, Date Tsunamune was arrested in Edo, for drunkenness and debauchery; the charges were generally believed to have been true. Tsunamune was condemned to excavate the moats which encircled the shōgun's Edo Castle. In 1660, he was ordered to supervise and pay for enhancing the north east moat running from Megane bashi to the Ushigome gate. The initial charges of licentious living are now believed to have been encouraged heavily by certain vassals and kinsmen in the north. These vassals and kinsmen appealed to the Council of Elders in Edo that Tsunamune should not be considered fit to rule, and that his son Date Tsunamura, great grandson of Masamune, should become the daimyō (lord) of the Date han (fief). Thus, Tsunamura became daimyō, under the guardianship of his uncles, Date Munekatsu and Muneyoshi. Ten years of violence and conflict followed in the north, reaching a climax in 1671 when Aki Muneshige, a powerful relative of the Date, complained to the shogunate of the mismanagement of the fief under Tsunamura and his uncles. The episode that followed is so complex and dramatic as to warrant becoming a well known story known as the Date Sōdō (Date Disturbance) and a theatrical play as well. Aki was summoned to Edo to argue his case before various councils and officials, and was involved in a number of interrogations, examinations and meetings, as were several other retainers of the Date. One retainer in particular, Harada Munesuke, was a supporter of Tsunamura and his uncles and, it is said, made a poor impression at Edo. At one point, Aki came upon Harada waiting to meet with some of the officials, and Aki began shouting insults. Swords were then drawn, and Aki was killed. Harada was killed moments after, by the officials or their guards. The official verdict was that Harada drew first; the Harada family was disbanded and though Tsunamura was affirmed as the proper daimyō, his uncles were punished. Though the Date are most well known for their power in the north, Date Hidemune, the second son of Masamune, enjoyed a fief of 100,000 koku on Shikoku.

The tozama Date clan originated during the 12th century in Shimōsa Province. or Tamura Muneyoshi (1637–1678) settled himself at Ichinoseki domain (30,000 koku) in Mutsu Province (now in Iwate Prefecture), where his descendants resided up through 1868. The head of this clan line was ennobled as an hereditary "Viscount" in the Meiji period.

The Date clan's tutelary shrine, Kameoka Hachimangū, survives as a local shrine in Sendai.

These families were vassals of the Date clan. Notable members are listed by their date of birth.

The Date Clan is heavily featured in the anime series Masamune Datenicle. The Date are a playable faction in Shogun 2. Date is a playable nation in Europa Universalis IV.
