Sōma Yoshitane (daimyo, born 1548)

Sōma Yoshitane (相馬義胤) (1548–1635) was the 16th hereditary chieftain of the Sōma clan and a Sengoku period daimyō with territories covering the three districts forming the northern Hamadōri region of southern Mutsu Province.

Yoshitane was wed to Tanemune's younger daughter, Kosugō Gozen the following year.

Both Sōma Yoshitane and Date Masamune submitted to Toyotomi Hideyoshi at the Siege of Odawara.

[2] At the time of the Battle of Sekigahara, the Sōma attempted to remain neutral for fear of the powerful Satake clan to the south, which was allied with Ishida Mitsunari through marriage ties.

The new Tokugawa shogunate initially decided to seize the Sōma territories, but through the intervention of several senior retainers (including their former arch-enemy Date Masamune), the shogunate relented and appointed Yoshitanes son, Sōma Toshitane as a tozama daimyō over a 60,000 koku Sōma Nakamura Domain which encompassed their traditional holdings.
