Japanese Emperor Go-Kameyama abdicates in favor of rival claimant Go-Komatsu.
Emperor Go-Kameyama abdicated in 1392, concluding the Nanboku-chō period and uniting the Northern and Southern Courts under Go-Komatsu. This abdication ended decades of imperial rivalry in Japan.
During the Nanboku-chō period of Japanese history (1336–1392), rival Southern and Northern Courts each claimed legitimate rule. Southern Court Emperor Go-Kameyama, based in Yoshino, faced persistent pressure from the Ashikaga shogunate to reconcile. On October 21, 1392, Go-Kameyama formally abdicated in favor of Northern Court claimant Emperor Go-Komatsu in Kyoto. This agreement, brokered by Shogun Ashikaga Yoshimitsu, ended decades of dynastic struggle. Go-Kameyama was granted estates and an honorable retirement. Go-Komatsu’s accession reunited the imperial lineage under a single sovereign for the first time in over half a century. The compromise reinforced the shogunate’s authority while restoring nominal harmony to the emperor’s role. However, southern loyalists would continue to remember Go-Kameyama’s legacy for generations.

Tokugawa Ieyasu defeats the leaders of rival Japanese clans in the Battle of Sekigahara and becomes shōgun of Japan.
Tokugawa Ieyasu’s decisive victory at the Battle of Sekigahara in 1600 paved the way for his rule as shōgun, initiating over 250 years of Tokugawa shogunate. The battle ended decades of civil strife and unified Japan under a central military government.
The Battle of Sekigahara, fought on October 21, 1600, is often called the most important clash in Japanese history. Forces loyal to Tokugawa Ieyasu (Eastern Army) faced those allied with Toyotomi Hideyori under Ishida Mitsunari (Western Army) on the plains of Gifu. Strategic defections and superior tactics allowed Ieyasu to encircle and rout his opponents within hours. This decisive victory ended the Warring States period and removed the last major obstacle to Tokugawa dominance. In 1603, Ieyasu was appointed shōgun by Emperor Go-Yōzei, establishing the Tokugawa shogunate. Under his bakuhan system, Japan enjoyed over two centuries of relative peace and stability. The battle’s legacy endures as a symbol of military acumen and the birth of modern Japan.

A secret society in the Imperial Japanese Army launches an abortive coup d'état attempt.
A radical faction within the Imperial Japanese Army attempts a dramatic coup d'état in Tokyo.
On this day in 1931, a clandestine group of young officers in the Imperial Japanese Army made a bold but ill-fated bid to overthrow the civilian government. Motivated by ultra-nationalist aims and dissatisfaction with political leaders, they sought to establish a military dictatorship. The coup plotters seized key locations in Tokyo but failed to secure wider support from senior commanders. Government forces swiftly suppressed the uprising and arrested the conspirators. The episode exposed deep tensions between military and political elites in pre-war Japan. It also foreshadowed the growing influence of militarism leading up to World War II.

World War II: The Provisional Government of Free India is formally established in Japanese-occupied Singapore.
Subhas Chandra Bose proclaims the establishment of the Provisional Government of Free India in Singapore.
On this day in 1943, nationalist leader Subhas Chandra Bose declared the formation of the Provisional Government of Free India (Azad Hind) in Japanese-occupied Singapore. Supported by the Axis powers, the government aimed to rally Indian troops and expatriates against British colonial rule. Bose served as its head, emphasizing military efforts alongside diplomatic outreach. Although lacking international recognition beyond Axis states, the Provisional Government inspired Indian independence activists. It organized the Indian National Army, which engaged Allied forces in Southeast Asia. The experiment ended with Japan’s defeat in 1945, but it left a legacy of committed anti-colonial activism.
