Hvem daterede Tokugawa Ieyasu?

Tokugawa Ieyasu (born Matsudaira Takechiyo; 31 January 1543 – 1 June 1616) was the founder and first shōgun of the Tokugawa shogunate of Japan, which ruled from 1603 until the Meiji Restoration in 1868. He was the third of the three "Great Unifiers" of Japan, along with his former lord Oda Nobunaga and fellow Oda subordinate Toyotomi Hideyoshi. The son of a minor daimyo, Ieyasu once lived as a hostage under daimyo Imagawa Yoshimoto on behalf of his father. He later succeeded as daimyo after his father's death, serving as ally, vassal, and general of the Oda clan, and building up his strength under Oda Nobunaga.

After Oda Nobunaga's death, Ieyasu was briefly a rival of Toyotomi Hideyoshi, before declaring his allegiance to Toyotomi and fighting on his behalf. Under Toyotomi, Ieyasu was relocated to the Kanto plains in eastern Japan, away from the Toyotomi power base in Osaka. He built his castle in the fishing village of Edo (now Tokyo). He became the most powerful daimyo and the most senior officer under the Toyotomi regime. Ieyasu preserved his strength during Toyotomi's failed attempts to conquer Korea. After Hideyoshi's death and the Battle of Sekigahara, Ieyasu seized power in 1600.

He received appointment as shōgun in 1603, and voluntarily resigned from his position in 1605, although he still held the de facto control of government until his death in 1616. He implemented a set of careful rules known as the bakuhan system. This system used precisely graded rewards and punishments to encourage (or compel) the daimyo and samurai to live in peace with each other under the Tokugawa Shogunate.

Lady Saigō (西郷局 or 西郷の局 Saigō no Tsubone; 1552 – 1 July 1589), also known as Oai, was one of the concubines of Tokugawa Ieyasu, the samurai lord who unified Japan at the end of the sixteenth century and then ruled as shōgun. She was also the mother of the second Tokugawa shōgun, Tokugawa Hidetada. Her contributions were considered so significant that she was posthumously inducted to the Senior First Rank of the Imperial Court, the highest honor that could be conferred by the Emperor of Japan.

During their relationship, Lady Saigō influenced Ieyasu's philosophies, choice of allies, and policies as he rose to power during the late Sengoku period, and she thus had an indirect effect on the organization and composition of the Tokugawa shogunate. Although less is known of her than some other figures of the era, she is generally regarded as the "power behind the throne", and her life has been compared to a "Cinderella story" of feudal Japan.

Once she was in a respected and secure position as the official concubine and mother to Ieyasu's heir, Lady Saigō used her influence and wealth for charitable purposes. A devout Buddhist, she donated money to temples in Suruga Province, where she resided as the consort of Ieyasu, first in Hamamatsu Castle and later in Sunpu Castle. As she was quite near-sighted, she also established a charitable organization that assisted visually impaired women with no other means of support. Lady Saigō died at a fairly young age, under somewhat mysterious circumstances. Although murder was suspected, no culprit was identified.

Lady Saigō bore four children: she had a son and a daughter (Saigō Katsutada and Tokuhime) while married, and she later bore two sons as the consort of Tokugawa Ieyasu: Tokugawa Hidetada and Matsudaira Tadayoshi. Among the descendants of Lady Saigō was the Empress Meishō (1624–1696), one of very few women to accede to the Chrysanthemum Throne as empress regnant.
