The () were the most powerful feudal rulers from the 10th century to the 19th century in Japan. The term "daimyo" literally means "great name." From the ''shugo'' of the Muromachi period through the ''sengoku'' to the daimyo of the Edo period, the rank had a long and varied history. The term "daimyo" is also sometimes used to refer to the leading figures of such clans, also called "lord". It was usually, though not exclusively, from these warlords that a shogun arose or a regent was chosen.
The daimyo usually wore purples, ranging from dark to light depending on how high ranked they were. Dark and light purple preceded dark and light green, dark and light red, and finally black. The very highest daimyo were considered to be nobles.

Daimyo in the Edo period

After the Battle of Sekigahara in the year 1603 that marked the beginning of the Edo period, shogun Tokugawa Ieyasu reorganized roughly 200 daimyo and their territories, formerly provinces (''kuni''), into the ''han,'' and rated them based on their production of rice. Daimyo were those who headed ''han'' assessed at 10,000 koku (50,000 bushels) or more. Ieyasu also categorized the daimyo according to how close they were to the ruling Tokugawa family, who were known for their bravery: ''shinpan'', who were related to the Tokugawa, the ''fudai'', who had been vassals of the Tokugawa or allies in the battle, and the ''tozama'', who opposed the Tokugawa but were defeated.
Around 1800, there were approximately 170 daimyo in Japan.
The ''shinpan'' were collaterals of Ieyasu, such as the Matsudaira, or descendants of Ieyasu other than in the main line of succession. Several ''shinpan,'' 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 ''rōjū.'' The fact that ''fudai'' daimyo could hold government positions while ''tozama,'' in general, could not was a main difference between the two.
''Tozama'' daimyo held large fiefs, with the Kaga ''han'' of Ishikawa Prefecture, headed by the Maeda clan, assessed at 1,000,000 koku. Other famous ''tozama'' clans included the Mori of Chōshū, the Shimazu of Satsuma, the Date of Sendai, the Uesugi of Yonezawa, and the Hachisuka of Awa. Initially, the Tokugawa regarded them as potentially rebellious, but for most of the Edo period, marriages between the Tokugawa and the ''tozama,'' as well as control policies such as ''sankin kotai,'' resulted in peaceful relations.

Sankin kōtai

Sankin kōtai ("alternate attendance") was the system whereby the Tokugawa forced all daimyo to spend every other year at the Tokugawa court in Edo, and maintain their family members in Edo when they returned to their ''han''. This increased political and fiscal control over the daimyo by Edo. As time went on in the Tokugawa period, many other systems of controlling the daimyo were put into place, such as mandatory contributions to public works such as road building. In addition, daimyo were forbidden to build ships and castles, and other shows of military power were often tightly controlled.
Upset by these controls, and often in bad economic situations because of things like ''sankin kotai,'' forced support of public works, and extravagant spending, several daimyo sided against the Tokugawa Shogunate during the Meiji Restoration.

After the Meiji Restoration

In 1869, the year after the Meiji Restoration, the daimyo, together with the ''kuge,'' formed a new aristocracy, the ''kazoku.'' In 1871, the han were abolished and prefectures were established, thus effectively ending the daimyo era in Japan. However, many daimyo remained in control of all or part of their ancestral lands, being appointed by the Emperor as governors of the newly created prefectures.
