Tokugawa Hidetada in the context of "Oeyo"

The Edo period, also known as the Tokugawa period, is the period between 1600 or 1603 and 1868 in the history of Japan, when the country was under the rule of the Tokugawa shogunate and some 300 regional daimyo, or feudal lords. Emerging from the chaos of the Sengoku period, the Edo period was characterized by prolonged peace and stability, urbanization and economic growth, strict social order, isolationist foreign policies, and popular enjoyment of arts and culture.

In 1600, Tokugawa Ieyasu prevailed at the Battle of Sekigahara and established hegemony over most of Japan, and in 1603 was given the title shogun by Emperor Go-Yōzei. Ieyasu resigned two years later in favor of his son Hidetada, but maintained power, and defeated the primary rival to his authority, Toyotomi Hideyori, at the Siege of Osaka in 1615 before his death the next year. Peace generally prevailed from this point on, making samurai largely redundant. Tokugawa shoguns continued Ieyasu's policies of conformity, including a formalization of social classes in a strict hierarchy. By 1639, all foreigners were expelled under the policy of sakoku, with the exception of Dutch traders on the island of Dejima in Nagasaki, beginning a period of isolation. From 1635, daimyō had to spend alternating years in the capital Edo, where their family was required to reside permanently, in a system of "alternate attendance" in order to keep them in check.

Tokugawa Iemitsu (徳川 家光; 12 August 1604 – 8 June 1651) was the third shōgun of the Tokugawa dynasty. He was the eldest son of Tokugawa Hidetada with Oeyo, and the grandson of Tokugawa Ieyasu. Lady Kasuga was his wet nurse, who acted as his political adviser and was at the forefront of shogunate negotiations with the Imperial court. Iemitsu ruled from 1623 to 1651; during this period he crucified Christians, expelled all Europeans from Japan and closed the borders of the country, a foreign policy that continued for over 200 years after its institution.

Tokugawa Tsunayoshi (徳川 綱吉; 23 February 1646 – 19 February 1709) was a Japanese samurai, daimyo and the fifth shōgun of the Tokugawa dynasty of Japan. He was the younger brother of Tokugawa Ietsuna, the son of Tokugawa Iemitsu, the grandson of Tokugawa Hidetada, and the great-grandson of Tokugawa Ieyasu.

Tsunayoshi is known for instituting animal welfare laws, particularly for dogs. This earned him the nickname of "the dog Shogun" (Inu-Kubō 犬公方: Inu=Dog, Kubō=formal title of Shogun).

Yodo-dono (淀殿) or Yodo-gimi (淀君; [jo.do(ꜜ).ɡʲi.mʲi, -ŋʲi.mʲi], 1569 – June 4, 1615), also known as Lady Chacha (茶々; [tɕaꜜ.tɕa]), was a Japanese historical figure in the late Sengoku period. She was the concubine and the second wife of Japanese ruler Toyotomi Hideyoshi. As the mother of his son and successor Hideyori, she acted as Hideyori's guardian in the restoration of the Toyotomi clan after the fall of the Council of Five Elders, and alongside her son, led the last anti-Tokugawa shogunate resistance in the siege of Osaka.

She was the daughter of Oichi and sister of Ohatsu and Oeyo. When her two younger sisters became prominent members linked to the Tokugawa clan, she and her sisters became vital to maintaining the diplomatic relations between the two most powerful clans of the time, Toyotomi and Tokugawa. Her sister, Oeyo, was the wife of the second shogun, Tokugawa Hidetada, and matriarch of the successive shoguns' lineage, thus receiving the political title Omidaidokoro.

Tokugawa Masako (徳川 和子; November 23, 1607 – August 2, 1678), also known as Kazu-ko, was empress consort of Japan as the wife of Emperor Go-Mizunoo. Through collaboration with her parents, Oeyo and Shogun Tokugawa Hidetada, she was a prominent and influential figure within the politics and culture of the Edo Period.

Kujō Yukiie (九条 幸家; April 7, 1586 – September 29, 1665), son of regent Kanetaka, was a kugyō or Japanese court noble of the Edo period (1603–1868). His given name was initially忠栄 (Tadahide). He held a regent position kampaku from 1608 to 1612 and from 1619 to 1623. He married Toyotomi Sadako (1592–1658), a daughter of Toyotomi Hidekatsu and Oeyo and adopted daughter of shōgun Tokugawa Hidetada. The couple had, among other children, sons Nijō Yasumichi, Kujō Michifusa, Matsudono Michimoto (1615-1646).
