Emperor Go-Daigo returns to Kyōto and attempts to reassert direct imperial government after the fall of the Kamakura shogunate, setting the stage for conflict with powerful warrior leaders.
Ashikaga Takauji turns against Go-Daigo, captures Kyōto, and supports a rival imperial line—triggering the Northern and Southern Courts split and accelerating the rise of Ashikaga-led military government.
Ashikaga Takauji formally establishes the Ashikaga (Muromachi) shogunate, inaugurating a military regime that would govern Japan amid growing provincial autonomy.
Ashikaga Yoshimitsu establishes a major shogunal residence in Kyōto (later associated with the ‘Flower Palace’/Hana no Gosho), strengthening the shogunate’s presence in the capital and giving the period its common name.
Ashikaga Yoshimitsu brokers settlement between the rival courts, ending the Nanboku-chō division; imperial succession thereafter follows the Northern Court line, while regional military power continues to expand.
Ashikaga Yoshimitsu builds the Golden Pavilion complex (later the Zen temple Rokuon-ji/Kinkaku-ji), emblematic of elite Muromachi culture and shogunal patronage of the arts.
To reopen profitable official relations with Ming China, Yoshimitsu engages in tributary-style diplomacy and receives recognition as “King of Japan,” linking foreign trade to shogunal authority.
A succession dispute within the Ashikaga establishment ignites the Ōnin War, fought largely in Kyōto; the destruction accelerates the breakdown of central control and opens a long era of regional warfare.
In Yamashiro Province, local samurai and peasants organize an ikki league, force the withdrawal of rival warlord forces, and run a confederated provincial government—an example of bottom-up rule amid shogunal weakness.
A large-scale uprising in Kaga Province overthrows the shugo Togashi Masachika and helps establish sustained Ikkō-ikki influence, illustrating how religious and local leagues could displace hereditary governors.
Hosokawa Masamoto removes the sitting shogun and installs a replacement, demonstrating how powerful deputies and regional magnates could control—or fracture—the shogunate’s legitimacy and succession.
Rival Japanese delegations (Ōuchi and Hosokawa) clash in Ningbo, prompting a breakdown in official trade relations with Ming China and contributing to increased coastal piracy (wokou), further weakening shogunal control of foreign commerce.
Portuguese traders land at Tanegashima and introduce matchlock firearms, which spread quickly through Japan and intensify Sengoku-era conflict dynamics and castle warfare.
Oda Nobunaga defeats and kills Imagawa Yoshimoto in a surprise victory, dramatically shifting the balance among Sengoku warlords and setting Nobunaga on a path toward dominating central politics.
With military backing from Oda Nobunaga, Ashikaga Yoshiaki enters Kyōto and takes the shogunate, illustrating the shogun’s increasing dependence on regional warlords for power.
Oda Nobunaga deposes and banishes Ashikaga Yoshiaki from Kyōto, conventionally marking the end of Ashikaga (Muromachi) rule and the transition toward unification under warlord regimes.
