Rise to Power

Battle of Yamazaki and conflict with Katsuie

After the assassinations at Honnō-ji of Oda Nobunaga and his eldest son Nobutada in 1582 at the hands of Akechi Mitsuhide, Hideyoshi, seeking vengeance for the death of his beloved lord, made peace with the Mōri clan and defeated Akechi at the Battle of Yamazaki.

At a meeting at Kiyosu to decide on a successor to Nobunaga, Hideyoshi cast aside the apparent candidate, Oda Nobutaka and his advocate, Oda clan's chief general, Shibata Katsuie, by supporting Nobutada's young son, Oda Hidenobu. Having won the support of the other two Oda elders, Niwa Nagahide and Ikeda Tsuneoki, Hideyoshi established Hidenobu's position, as well as his own influence in the Oda clan. Tension quickly escalated between Hideyoshi and Katsuie, and at the Battle of Shizugatake in the following year, Hideyoshi destroyed Katsuie's forces and thus consolidated his own power, absorbing most of the Oda clan into his control.

Constructing of Osaka Castle

In 1583, Hideyoshi began construction of Osaka Castle. Built on the site of the temple Ishiyama Hongan-ji destroyed by Nobunaga, the castle would become the last stronghold of the Toyotomi clan after Hideyoshi's death.

Battle of Komaki and Nagakute

Nobunaga's other son, Oda Nobukatsu, remained hostile to Hideyoshi. He allied himself with Tokugawa Ieyasu, and the two sides fought at the inconclusive Battle of Komaki and Nagakute. It ultimately resulted in a stalemate, although Hideyoshi's forces were delivered a heavy blow. Finally, Hideyoshi made peace with Nobukatsu, ending the pretext for war between the Tokugawa and Hashiba clans. Hideyoshi sent Tokugawa Ieyasu his younger sister Asahi no kata and mother Ōmandokoro as hostages. Ieyasu eventually agreed to become a vassal of Hideyoshi.

  Early Life: Very little is known for certain about Hideyoshi before 1570, when he begins to appear in surviving documents and letters. His autobiography starts in 1577 but in it Hideyoshi spoke very little about his past.

  Service under Nobunaga: In 1558, he joined the Oda clan, now headed by Oda Nobunaga, as an ashigaru. He became one of Nobunaga's sandal-bearers and was present at the Battle of Okehazama in 1560 when Nobunaga defeated Imagawa Yoshimoto to become one of the most powerful warlords in the Sengoku period.

  Rise to Power: After the assassinations at Honnō-ji of Oda Nobunaga and his eldest son Nobutada in 1582 at the hands of Akechi Mitsuhide, Hideyoshi, seeking vengeance for the death of his beloved lord, made peace with the Mōri clan and defeated Akechi at the Battle of Yamazaki.

  Pinnacle of Power: The 1590 Siege of Odawara against the Hōjō clan in the Kantō region eliminated the last resistance to Hideyoshi's authority. His victory signified the end of the Sengoku period.

  Decline of Power: The stability of the Toyotomi dynasty after Hideyoshi's death was put in doubt with the death of his son Tsurumatsu in September 1591.

  Death: His death was kept secret by the Council of Five Elders to preserve morale, and the Japanese forces in Korea were ordered to withdraw back to Japan by the Council of Five Elders.

  Cultural Legacy: Toyotomi Hideyoshi changed Japanese society in many ways. These include imposition of a rigid class structure, restriction on travel, and surveys of land and production.
