Date

The Date clan (伊達氏, Date uji), or the Idate clan according to seventeenth century Roman and Edo period records, is one of the few samurai families from ancient times to remain active in Japan today. They originated from the Fujiwara Hokke, founded by Fujiwara no Fusasaki and one of the families four main branches. According to the Azuma Kagami, the clan's origin began by a servant of Minamoto no Yoritomo originally named Hitatchi Ninyoudosai. Settling for a time in Isa Province, a branch of his descendants named themselves Date. The family broke off into several places of the land by the Kamakura period. The clan's seventh head destroyed the Nagai family and took their territory. He eventually surrendered to the Ashikaga shogunate.

However, the first Masamune opposed his family's lands being cut and made a quiet rebellion during his later years. He allied with the Ōsaki clan and fought Yuuko Mitsutomo and Uesugi Zenshū. Though the battle's results remain unclear, his family's reputation was given a significant boost and praised. A mere feudal lord with little land became a great lord of Mutsu Province (later known as Oshu) when he subjugated Kamakura and other parts of the land for the shogunate. By the late 1400's, the Date was recognized as a powerful clan.

During the Warring States Period, Masamune heavily pushed for an expansion of his land's borders. Skilled with warfare and politics, he took advantage of the weakened Ashikaga shogunate and chose to subjugate several of the shogunate's retainer families. By 1589, Oshu was largely expanded to its maximum potential. After Hideyoshi subdued the Hojo, he set his sights on the Date. Due to Ieyasu's negotiations, an all out war was avoided and the Date submitted. Hideyoshi relieved them 72,000 koku. Allying with Ieyasu for the rest of his campaigns, the Date received rewards for the majority of the time era as a tozama daimyo. Eventually, Masamune established Sendai and the clan kept a relatively high reputation ever since. Today, current leaders of the Date clan continue to be influential figures in Sendai.

Yasumune was born in Tokyo and succeeded his family estate in Sendai after his father's passing.
