真田氏
By 1582, the Oda-Tokugawa forces had destroyed the Takeda clan. The Sanada initially surrendered to Oda Nobunaga, but, after the incident at Honnō-ji, it became independent again, drifting between stronger "daimyōs" such as the Uesugi clan, the Later Hōjō clan, and the Tokugawa clan. Eventually, the Sanada clan became a vassal of Toyotomi Hideyoshi.
