Honda Tadakatsu
A number of other clans which were not retainers of the Tokugawa before the Azuchi–Momoyama period also came to be counted as "fudai", such as the Ogasawara and the Doi. Honda Tadakatsu, Sakakibara Yasumasa, Sakai Tadatsugu, and Ii Naomasa — Tokugawa Ieyasu's "Four Great Generals" — were all pre-Edo period "fudai" who went on to become "fudai daimyōs". In addition, some branches of the Matsudaira clan, from which the Tokugawa clan originated, were classed as "fudai" while allowed to retain the Matsudaira name.
