Hōjō Ujitsuna was a prominent Japanese samurai and the 14th head of the Hōjō clan. He lived during the late 16th century and played a significant role in the Sengoku period, a time of intense military conflict in Japan. Ujitsuna was known for his strategic skills and leadership, which helped maintain the clan's power in the Kanto region. Under Ujitsuna's leadership, the Hōjō clan expanded its influence and territory. He was also involved in various military campaigns against rival clans, including the Takeda clan. Ujitsuna's reign marked a period of relative stability for the clan until the eventual decline of the Hōjō during the rise of the Tokugawa shogunate.
