Date Hidemune was a Japanese daimyō during the early Edo period, born in 1591 as the eldest son of Date Masamune, one of Japan’s most prominent feudal lords. His mother was Shinzo no Kata, a concubine, which affected his future prospects. As a young man, Hidemune lived under the care of Toyotomi Hideyoshi and was given the adult name "Hidemune," adopting one character from Hideyoshi's own name. Hideyoshi granted Hidemune the court rank of junior 5th, lower grade, along with the title of ji-jū, and appointed him as a page to his son, Toyotomi Hideyori.
After Hideyoshi's death in 1600, Hidemune was held as a hostage in the residence of Ukita Hideie. Although he was Masamune's eldest son, Hidemune’s birth by a concubine made him ineligible to inherit the Sendai Domain. Instead, Masamune arranged for Hidemune to establish a branch of the Date family. This opportunity came in 1614 when they both participated in the Osaka Campaign. As a reward, Tokugawa Ieyasu granted Masamune the 100,000 koku Uwajima Domain, which was passed to Hidemune, making him the daimyō of Uwajima. Hidemune ruled the domain until his retirement in 1657.
