Ikeda-Tsuneoki.jpg

Ikeda Tsuneoki (1536 – May 18, 1584), also known as Ikeda Nobuteru, was a prominent daimyo of the Ikeda clan and a distinguished military commander during Japan's Sengoku and Azuchi-Momoyama periods. He served under the influential warlords Oda Nobunaga and Toyotomi Hideyoshi. Tsuneoki’s connection to Nobunaga began early, as his mother, Yotokuin, was Nobunaga’s wet nurse and later became a concubine to Oda Nobuhide, Nobunaga's father.

Early Life and Background

Tsuneoki’s childhood name is unknown, but he was commonly called Katsuzaburo. His father, Ikeda Tsunetoshi, served Oda Nobuhide. Born in one of several debated provinces (Owari, Mino, Settsu, or Omi), Tsuneoki rose to prominence as one of the four karo (senior retainers) at Kiyosu Castle. He held the title of Kii-no-kami ("Governor of Kii Province") and adopted the courtesy name Shozaburo. Later in life, after becoming a priest, he referred to himself as Shonyū.

Military Achievements

1556–1570: Early Campaigns

  • In 1556, Tsuneoki played a key role in suppressing the treasonous Oda Nobuyuki, Nobunaga’s younger brother.
  • In 1560, he led forces in the historic Battle of Okehazama against Imagawa Yoshimoto.
  • By 1570, he commanded troops at the Battle of Anegawa, contributing to Nobunaga’s victory over the Azai-Asakura alliance.

1571–1577: Consolidation of Power

  • Tsuneoki participated in the Siege of Mount Hiei, a campaign to neutralize the militant Buddhist monks of Ishiyama Honganji, and the attacks on Nagashima Ikko-ikki.
  • He fought at the Siege of Makishima Castle in 1573, securing the surrender of Ashikaga Yoshiaki, the last Ashikaga shogun.
  • Tsuneoki’s victories continued at the Battles of Nagashino (1575) and Tedorigawa (1577), where he fought the Takeda and Uesugi clans, respectively.

1580–1582: Rising Influence

  • In 1580, Tsuneoki captured Hanakuma Castle, defeating Araki Murashige, and was rewarded with domains in Settsu Province.
  • Following the Incident at Honnō-ji in 1582, Tsuneoki led 4,000 troops under Hashiba Hideyoshi’s command at the Battle of Yamazaki, defeating Akechi Mitsuhide. He also participated in the Kiyosu Castle conference, which determined Nobunaga’s successor.

1583–1584: Final Campaigns

Legacy

Despite his tragic death, Tsuneoki’s legacy endured through his children. His daughter Ikeda Sen survived the battle, and his second son, Ikeda Terumasa, succeeded him as head of the Ikeda clan. Terumasa later became a prominent daimyo under the Tokugawa shogunate. Tsuneoki is remembered as a loyal and skilled commander who played a crucial role in shaping the political and military landscape of his era.
