Similar to the feudal system in Europe, they held dynastic control over territories that had varying degrees of autonomy; lesser territorial lords were pledged to support greater ones.

At the beginning of the Edo period, their clans and territories were reorganized into the han, based on their production of rice. Daimyo headed hans assessed at 10 000 koku (50 000 bushels) or more.

The shimpan were collaterals of Ieyasu, such as the Matsudaira, or descendants of Ieyasu other than in the main line of succession. Several shimpan, including the Tokugawa of Owari ( Nagoya), Kii ( Wakayama) and Mito, as well as the Matsudaira of Fukui and Aizu, held large han.
A few fudai daimyo, such as the Ii of Hikone, held large han, but many were small. The shogunate placed many fudai at strategic locations to guard the trade routes and the approaches to Edo. Also, many fudai daimyo took positions in the Edo shogunate, some rising to the position of roju.
The term daimyo is also sometimes used to refer to the leading figures of such clans, also called "warlords". It was usually, though not exclusively, from these warlords that a shogun arose or a regent was chosen.
