Daimyo in AP World History: Modern
Daimyo were the regional lords of feudal Japan who held hereditary land domains, taxed the peasants who farmed them, and commanded their own samurai. They owed loyalty to the shogun, Japan's top military ruler, and the Meiji government abolished their domains in 1871 and replaced them with centrally run prefectures.
This definition is part of Fiveable's AP World History: Modern review, which also has guided practice questions.
Lords between the shogun and the samurai
Japan's feudal order ran emperor, shogun, daimyo, samurai, peasants. The emperor reigned as a mostly symbolic figure. Real power sat with the shogun's military government, called the bakufu (or shogunate).
A daimyo ran his domain much like a small state. He collected rice taxes, kept order, and supported samurai who owed him personal loyalty under the warrior code later called bushido. In return, the daimyo owed loyalty and military service to the shogun.
That loyalty was often shaky. Under the Tokugawa shogunate (1603-1868), the shogun kept more than 250 daimyo in line through alternate attendance (sankin-kotai). Daimyo had to spend alternate years in the capital, Edo, and leave their families there when they went home. It was an expensive system and worked partly as a hostage system.
Daimyo and the warrior society Buddhism entered, 1200-1450
Daimyo connect to two places in the course. The first is Unit 2 (Networks of Exchange), Topic 2.5: Cultural Consequences of Connectivity, which asks how Afro-Eurasian contact spread ideas and culture. The second is Unit 5 (Revolutions), Topic 5.6: Government & Industrialization, 1750 to 1900, which asks why some states built their own industrial programs and what came of them.
In the Unit 2 period, Japan was ruled by warriors. The Kamakura shogunate appointed military governors to the provinces. Under the later Ashikaga shogunate, many of those governors grew into the powerful regional lords who became the daimyo.
Topic 2.5 lists Buddhism's impact on East Asia as an example of cultural diffusion, and Japan's warrior elite is part of that story. Zen Buddhism, carried from China, found strong patrons among the warrior class. Daimyo themselves aren't what Topic 2.5 asks about. They're the political setting for a diffusion example the topic does ask about.
Why Meiji reformers had to get rid of the domains
Topic 5.6 says growing U.S. and European influence in Asia pushed Japan into internal reforms, and those reforms supported industrialization and turned Japan into a regional power during the Meiji Era. The daimyo system was one of the biggest obstacles those reforms had to remove.
The pressure began when Matthew Perry's U.S. warships arrived in 1853. The 1854 Convention of Kanagawa opened two ports to U.S. ships for supplies, and later treaties expanded trade on terms that favored the Western powers. The shogunate looked too weak to resist. In 1868, rebels from powerful domains overthrew the Tokugawa and restored power in the name of the Meiji emperor.
It was hard to build railroads, factories, and a national army while hundreds of lords each controlled their own land, taxes, and soldiers. In 1869 the daimyo returned their domains to the emperor. In 1871 the domains were abolished and replaced with prefectures governed from Tokyo. Former daimyo received payments and noble titles, but they lost their land and armies. National taxes and a conscript army replaced private samurai forces.
Abolishing the domains strengthened the central government's authority and helped it mobilize resources for industrialization. With land taxes flowing to the center, the state could put more money into factories, railways, and shipyards. Japan's win in the Sino-Japanese War (1894-1895) showed how far it had come.
Using the end of the daimyo as evidence
A Meiji government document announcing the 1871 abolition of the domains could easily show up as a multiple-choice stimulus for Topic 5.6, and so could a map or a historian's passage. It might ask about causes or effects. If a question asks what Japan's reforms involved or who lost power, the answer involves centralization at the expense of the daimyo and samurai.
In Short-answer question 1 (Secondary source) or Short-answer question 2 (Primary source), the abolition of the domains in 1871 is the kind of specific detail that turns a vague claim into a scored one. Writing "Japan modernized" is too general. Writing "the Meiji state abolished the daimyo domains and replaced them with prefectures, strengthening the central government's control over taxes it could use for industry" is specific enough.
For Question 2 (Long essay) on state-led industrialization, pair Japan with Muhammad Ali's push to build cotton-based textile manufacturing in Egypt, the course's illustrative example. Both governments centralized power to support state-led economic programs. The particular reforms differed. Muhammad Ali focused on state-run textile factories built around Egyptian cotton, while Meiji Japan abolished the domains, created a conscript army, and invested in railways and shipyards. The outcomes differed too. Egypt's industrial effort didn't last, and Britain occupied Egypt in 1882, while Japan defeated China in 1894-1895 and became a regional power. Comparing those specific reforms and results gives you a stronger thesis than a general claim that one country tried harder.
Shogun, daimyo, samurai: keeping the ranks straight
One easy slip is treating "shogun" and "daimyo" as the same thing. There was one shogun at a time, ruling the whole country through the bakufu, and there were many daimyo, each ruling one domain. If a stimulus describes a regional lord serving a higher military ruler, that's a daimyo.
Samurai get mixed in too. Samurai were the warriors who served daimyo, and daimyo were lords who employed samurai. The Meiji reforms ended the privileges of both groups, which helps explain why some former samurai rebelled in the 1870s.
Another mistake is overlooking the Meiji state's role in early industrialization, even though private businesses also contributed. Topic 5.6 emphasizes state sponsorship, and abolishing the domains strengthened the central government's authority and helped it mobilize resources for that effort.
