About Date Hidemune
- Date Hidemune (?? ??, November 11, 1591 – July 8, 1658) was a Japanese daimyo of the early Edo period.
- He was the eldest son of Date Masamune, born in 1591 by Shinzo no Kata (a concubine).
- Coming of age while living with Toyotomi Hideyoshi, he received a character from Hideyoshi's name and took the adult name of Hidemune.
- Hideyoshi also granted him the court rank of junior 5th, lower grade (????, ju go-i no ge) and the title of ji-ju, appointing the young Hidemune as a page to his own son Toyotomi Hideyori.
- After Hideyoshi's death in 1600, he was made a hostage at the residence of Ukita Hideie. Though he was Masamune's eldest son, Hidemune was born by a concubine, and therefore could not be the successor to the Sendai Domain, which his father ruled.
- Masamune therefore considered the possibility of having Hidemune start a branch family.
- This was made possible in 1614, when father and son took part in the Osaka Campaign: Hidemune received the 100,000 koku Uwajima Domain which Tokugawa Ieyasu granted to Masamune.
- Hidemune immediately entered his new fief as daimyo, and ruled until his retirement in Meireki 3 (1657).
